Caution on Upgraded Apple Remote Desktop

Apple recently issued a minor bug fix upgrade for Apple Remote Desktop (client and server portions). MPG recommends caution in upgrading ARD for this update.

With the usual Apple Core Rot software incompetence, the “upgrade” destroyed my ability to get to one server, made getting to a 2nd server flaky, and the 3rd server has lucked out somehow—but I suspect problems will crop up just when I need to use ARD, a scary thought. But there seems to be a fix, see further below.

For the problem server on 10.8, I rebooted twice and reinstalled the latest applicable client—no go, that server is now unreachable. The built-in firewall is disabled. Searching the web, I see that Apple has been breaking things like this for some years now—pure incompetence.

This is stuff that until the update has worked for 7 years. The nitwits at Apple seem to think everyone runs only the latest OS; my servers run 10.8, 10.10, and 10.11. Apple does not respect its users enough to actually test its “upgrades”, a pattern worsening year by year.

Update: my iMac with Apple Remote Desktop 3.8 works fine with the problem server. But as soon as I updated to Apple Remote Desktop 3.9, the iMac also fails to be able to connect. Clearly Apple has BROKEN Apple Remote Desktop 3.9.

Update 2: the user comments on the App Store confirm these problems in spades.

The fix — check a box

Found by scanning the numerous complaints. Why does Apple Remote Desktop make no effort to warn of older clients and inform the user of this change, rather than mysteriously hanging on any/all attempts to connect? ARD darn well knows the OS version from the configuration and/or prior connection. Two hours of my time wasted due to Apple’s contemptible contempt for its users.

The weird thing is that this fix was not needed for one of the servers also running 10.8. It suggests yet more bugs.

Check the box to connect to older versions of macOS clients such as 10.8

Will the next Apple Mac Pro (if any) be the Final Straw that Puts the Nail in the 'Pro' Coffin?

Pro users need pro machines:

  • An option for at least 128GB memory.
  • Ability to use the latest and greatest PCIe video cards.
  • Thunderbolt 3 and USB 3.
  • Rock solid reliability.

Of the above, the PCIe slot issue is the #1 issue that makes the 2013 Apple Mac Pro an overpriced laughingstock for video professionals. This has been building as an issue for years now.

Quotes below from Marco Solorio of OneRiver Media in NVIDIA’s GTX 1080: The Tip Of The Iceberg?. The NVIDIA announcement referred to was May 2016; video cards are only going to become more powerful, already vastly outpacing the CPU for many tasks, at least when the GPU works properly (Apple’s GPU choice of AMD is hugely unpopular among pros). Emphasis added.

The announcement of the GTX 1080 is so big, that this card alone will most likely cause a shift in computer workstation ownership. Last year I wrote an article about how I upgraded our Mac Pro Tower with new CPUs, RAM, flash-based boot drives, and of course, the Titan X. The system still churns through heavy tasks, including working with 4.6K RAW footage, edited in real-time in DaVinci Resolve in 4K UHD timelines (even basic node structures play in real-time without the need for rendering).

But as good as that juiced up Mac Pro Tower is today, I know at some point, the time will have to come to an end, simply because Apple hasn’t built a PCIe-based system in many years now. As my article described, the alternative Mac Pro trashcan is simply not a solution for our needs, imposing too many limitations combined with a very high price tag.

The NVidia GTX 1080 might be the final nail in the coffin. I can guarantee at this point, we will have to move to a Windows-based workstation for our main edit suite and one that supports multiple PCIe slots specifically for the GTX 1080 (I’ll most likely get two 1080s that that new price-point).

I’m no stranger to working on Windows systems (I’ve built my own Windows boxes since Windows 3/NT) and have Windows systems running now in our facility. But with that said, I do prefer Apple OS X when possible. But with no support of a modern PCIe-based workstation from Apple, our hands are tied to move to Windows (we may get an HP Z840 system, something similar, or a custom build we’ll do in-house). Even if the GTX 1080 could be flashed for OSX, we wouldn’t be able to take full advantage of what the 1080 has to offer, due to The Mac Pro Tower’s older PCIe bus technology.

... With all that said, I see (and have already seen) a huge migration of longtime Apple users (such as me) going to Windows systems for their main workstation needs. The sheer power and lower cost is just too huge at this point. The NVidia GTX 1080 just compounded that point exponentially stronger.

...

The “juiced up Mac Pro” referred to is not a 2013 Mac Pro, but its predecessor. That is why used 2010/2012 Mac Pros are still strong sellers at OWC / MacSales.com.

The choice to embed non-upgradeable video cards in the 2013 Mac Pro and to omit PCIe slots spells the death knell for pro users looking to work with 4K/6K/8K video, 3D modeling and rendering, etc. A future Mac Pro (if any) that takes that same approach means that Apple has abandoned any pretense of offering pro machines.

Does Apple (Tim Cook) even “get” that the entire high-end pro market is going to abandon Apple over the next year because of a failure to meet the fundamental needs of professionals? His public statement that “great desktops” are coming must be seen as coming from the CEO of a phone and gadget company. MPG doubts that there is any 'pro' left in Apple, but hopes to be proven wrong.

OWC Thunderbolt 3 cable

OWC Thunderbolt 3 cables are now available, and shipping within a day or two.

OWC Premium Thunderbolt 3 USB-C cables are the perfect choice for your Thunderbolt 3 workflow. These premium quality cables are manufactured to the highest standard to deliver the incredible power of Thunderbolt technology, with models supporting data transfer speeds up to 40Gb/s and power delivery up to 60W and long cable runs.

That's enough throughput to drive two 4K displays simultaneously, or one 5K display. Experience the full high-performance capabilities of your Thunderbolt 3 and USB-C devices.

The cables come in two speeds, with the 40 Gb/sec cables substantially more expensive thn the 20 Gb/sec ones.

Thus it makes sense to use the 0.5 meter 40 Gb/sec cable if the devices is very close to the Mac. If the devices are to be daisy-chained and lack the need for more than 20 Gb/sec (few devices can even approach that speed), then place these last in a daisy-chain, and use the 20 Gb/sec cables.

SoftRAID Updated to Version 5.5.6

SoftRAID, which is what makes RAID work for the OWC Thunderbay 4 RAID-5 edition, has been updated to version 5.5.6.

Known Bugs:

  • In the first release of Mac OS 10.12, the First Aid function in Apple’s Disk Utility application has a bug which prevents it from working on SoftRAID volumes. You can use a command in a Terminal window to perform this same function (Disk Utility calls this same command). For more information, see our compatibility page: https:// softraid.com/pages/support/compatibility_notes.html
  • There is a bug reported in Parallels Desktop 10 software which can cause data corruption in your Windows virtual machines whether running on SoftRAID or AppleRAID volumes. You must install Parallels Desktop 11 or later if you are running on a SoftRAID or AppleRAID volume.

New features in version 5.5.6:

  • Sometimes, when email notifications are sent through a yahoo.com mail account, the subject line gets garbled. This is the result of some, but not all, yahoo email servers being able to handle Q-encoded UTF-8 text. The work around in version 5.5.6 is to detect when the outgoing email account is on yahoo.com and then convert the subject to straight ascii text.
  • SoftRAID Lite and SoftRAID Lite for ThunderBay now allow you to delete all volumes created by SoftRAID and SoftRAID for ThunderBay including volumes with RAID levels 4, 5 and 1+0.

Bugs fixed in version 5.5.6:

  • Fixed a bug in the SoftRAID Monitor which prevented it from reliably sending email notifications.
  • Fixed a bug in SoftRAID driver which could cause mirror volumes to rebuild instantly, leaving secondary disks with invalid data. This would only happen if more than one secondary disk was missing or out of sync. (SR-305).
  • Fix a bug in the SoftRAID driver which causes disk errors in mirror and RAID 1+0 volumes (SR-416).
  • Fixed a bug in the SoftRAID driver which could cause some RAID 1+0 volumes to fail early in the rebuild process with a disk error (SR-381).
  • Fixed problem which caused certifying 4 Kn disks (disks with 4 KB sectors).
  • The SoftRAID application no longer crashes when you attempt to create a volume with more than 16 disks (SR-399).
  • The volume tile now updates immediately when the user enables or disables the volume’s safeguard (SR-320).
  • Fixed a bug in the SoftRAID Monitor which could cause log entries to be corrupted or incomplete. This primarily affected the SoftRAID_Email.log file when SMTP logging was enabled.
  • Fixed a bug in the SoftRAID application which caused big pipes connected to the volume tiles to be missing 2 pixels on their left side when displayed on Macs with Retina displays (SR-374).
  • Fixed a problem with the filename of the Japanese QuickStart Guide. The filename was causing DiskWarrior to say that the file was incorrectly encoded (SR-415).
  • Fixed a bug in the SoftRAID Monitor which caused it to display the “Disk is missing from a mirror volume” dialog even when this preference was disabled (SR-413).
  • Fixed a bug in the SoftRAID driver which caused the SoftRAID Monitor status indicator in the menu bar to go yellow whenever a mirror read-only secondary volume was attached.
  • Fixed several broken links in the SoftRAID On-line help (SR-386).
  • Fixed a bug in the SoftRAID Monitor which caused it to sometimes skip the SMART test on startup. This would happen if you configured email notification to send an email on reboot. (SR-303 & SR-299).
  • Fixed a bug which caused Tech Support Reports to sometimes be missing volume headers (SR-238).
  • Fixed a bug in the SoftRAID driver which prevented it from warning users if a volume was missing a disk. Older versions of SoftRAID would only warn a user once. This version warns a user every time the startup or restart (SR-68).
  • Fixed a bug in the SoftRAID Monitor which caused some log entries to be truncated. This especially affected the log entries for disks which are predicted to fail (SR-407).
  • Fixed a bug which caused mirror read-only secondary volumes to be identified as mirror volumes in the SoftRAID log (SR-262).
  • Fixed a bug which allowed users to attempt to convert AppleRAID RAID 1+0 volumes (SR-406).
  • Fixed several bugs which caused incorrect error messages to be displayed when sending test emails in the Email Notification window.
  • Fixed a bug in the SoftRAID application which made the error count text in disk and volume tiles display incorrectly if there are 1 or more errors (SR-360).
  • Fixed a bug in the SoftRAID Monitor which caused the incorrect IPv4 address to be listed in email notifications (SR-392).
  • Fixed a bug in the SoftRAID applications which causes clipping of the text for the “Log SMT commands” preference button in the Servers tab of the Email Notification window. This clipping only occurs when the user is running with German as the chosen language.
  • Fixed two bugs in the SoftRAID application where the incorrect text was being displayed when the chosen language was Japanese. The incorrect text was displayed in the Preference and Quit menu items.
  • Fixed problem with the title of the Certify Disks dialog (SR-378).
  • Fixed a problem with the warning dialog which gets displayed if the user starts certifying an SSD with only 1 pass. The buttons were not translated (SR-379).
  • Fixed a typos in mirror dialogs (SR-362 and SR-349).
  • Fixed a bug in SoftRAID application which caused disconnected mirror secondary disks to become new volumes when reconnected. This occurred if an additional secondary disks was added to the volume while the first secondary disk was disconnected. (SES-348).
  • Fixed a bug which indicated that TRIM was enabled on an SSD when it was actually disabled in the SoftRAID preferences (SR-290).
  • Fixed a bug which caused the SoftRAID Monitor indicator to not appear in the menu bar if no SoftRAID formatted disks were attached (SR-386).
  • Fixed a bug which caused the SoftRAID Monitor to use a lot of CPU time when it first started up. This was accompanied by warning messages in the system.log file which said that SoftRAID Monitor was “inherently inefficient” (SR-318).
  • Improved the capture of volume headers in Tech Support Reports (SR-238).

Macular Degeneration Linked to Blue Light (sunlight and most forms of LED lights)

Love that iPhone or iPad or other phone or tablet or computer display? Long term, the blue light from cell phones and tablets and computer displays might have serious implications, and that’s no laughing matter, even if it takes 50 years for it to happen. It is particularly concerning since children from a very young age stare at cell phone or tablet screens for many hours. Excessive blue light is also linked to eyestrain and various health problems.

Observation: the iMac 5K display can be run extremely bright, and looks to contain a lot of blue light.

Macular degeneration (retinal cell death) has been linked to blue light (380nm to 500nm). The term HEV (high energy visible) might also be heard. A sampler:

To be clear, there is no scientific evidence yet that blue LED light will cause macular degeneration (leading to loss of vision) the same way sunlight does. It is a matter of intensity, duration of exposure, and almost certainly a complex interplay of personal factors (overall health, diet, genetics, etc).

From White Light–Emitting Diodes (LEDs) at Domestic Lighting Levels and Retinal Injury in a Rat Model (emphasis added):

LED (or solid-state) lighting sources are designed to emit all energy within the wavelength range of human vision, making LEDs the most energy-efficient commercially manufactured light. However, many current “white-light” LED designs emit much more blue light than conventional lamps, which has a number of health implications, including disruption of circadian rhythms (Holzman 2010).

The most popular LED lighting product, a phosphor-conversion (PC) LED, is an LED chip that emits blue light, which passes through a yellow phosphor-coating layer to generate the ultimate white light (Spivey 2011). Although the white light generated from LEDs appears normal to human vision, a strong peak of blue light ranging from 460 to 500 nm is also emitted within the white light spectrum; this blue light corresponds to a known spectrum for retinal hazards (Behar-Cohen et al. 2011). Some epidemiological studies have suggested that short-wavelength light exposure is a predisposing cause for age-related macular degeneration (AMD) (Wu et al. 2006). Animal models have also been used to determine that excessive exposure to blue light is a critical factor in photochemical retinal injury targeting photoreceptors and the retinal pigment epithelium (RPE) (Hafezi et al. 1997).

Things are often more complicated; tangled up in all this is the age factor: too little blue light can also be a problem, and age can be a mitigating factor of sorts because the lens of the eye yellows with age (yellow filters out blue). But if the damage accrues from youth to middle age, the yellowing lens is not of much help:

With age, the lens becomes more yellowish, and thus, the spectrum of blue light transmission dramatically decreases through the years. It is suspected that one reason older individuals experience sleep problems is the lack of blue light during the daytime.

Spectral transmission graphs

The closer the light wavelength is to ultraviolet (UV), the more damaging it becomes in general. This is true in general for skin cancer or killing viruses in water or degradation of plastics or paint or anything over time (just find any can or bottle that has been sitting in the sun for a long time). That’s because shorter wavelengths contain much higher energy levels (go beyond UV to X-Rays and killer gamma rays).

To assess UV/violet/blue exposure with a sunglass or contact lens, one would need a spectral transmission chart. Yet when I request spectral transmission charts no vendor has them, even first-class sunglass vendors like REVO. Statements like “blocks blue light” are presumably true, but ought to be backed up by hard 3rd-party evidence, that is, a spectral transmission chart showing just what is blocked—and this varies by the tint and coating of the lens used. Accordingly, I hope to actually measure the spectral transmission of sunglasses that I actually wear sometime soon.

Spectral transmission graph

The link between blue light and macular degeneration

In Macular Degeneration Linked to Sunlight and Low Antioxidants:

Some cases of age-related macular degeneration may arise from a combination of low plasma levels of antioxidants and exposure to blue light from the sun, a multinational European study suggested.

The combination more than tripled the risk of the eye disease among individuals with the lowest combined levels of antioxidants, Astrid E. Fletcher, Ph.D., of the London School of Hygiene and Tropical Medicine, and colleagues reported in the October issue of Archives of Ophthalmology.

...

I’ve also spoken to an optometrist who regularly snapshots the retinas as part of eye exams, and he states (for my eyes and in general) that he has not observed any change in retina health in recent years. Thus theoretical lab tests are no subsitute for real-world scientific evidence as per retinal cells in human eyes, particularly given outdoor light exposure. That said, many of us spend many hours staring at bluish LED displays (cell phones, tablets, computer displays) and/or under LED or CFL lighting in the home or office.

The blue light from LEDs is now associated with retinal cell death. How much is too much is as yet unknown, but the evidence leaves little doubt that blue light kills retinal cells:

The relation between macular degeneration-retinal damage and exposure to light has been known since the middle of the 20th century. Nevertheless, in the last 5 years, the advent of new technology LED along with its massive use in screens of electronic devices (smartphones, tablets, laptops…) has made phototoxicity the main field of our research.

The studies conducted by the Complutense University of Madrid have shown that LED devices emit 5 times more toxic light than light reflected by paper or emitted by the older-style CRT monitors.

In-vitro experiments in which human donated retinal pigmentary epithelium cells were exposed to 36-hour circadian cycles of direct LED light of different intensities have been forceful: without protection, cell death amounted to 93%. However, when a protective element was placed between the cells and LED light, the survival rate of cells increased by 90%... Dr Sánchez-Ramos acknowledges that it may take another 10-15 years for research to demonstrate conclusively that LED light causes macular degeneration in the same way that sunlight does.

See also The Lowdown on Blue Light: Good vs. Bad, and Its Connection to AMD.

Nowadays, there's an increase in the use of digital devices and modern lighting—such as LED lights and compact fluorescent lamps (CFLs)—most of which emit a high level of blue light. CFLs contain about 25% of harmful blue light and LEDs contain about 35% of harmful blue light. Interestingly, the cooler the white LED, the higher the blue proportion. And by 2020, 90% of all of our light sources are estimated to be LED lighting. So, our exposure to blue light is everywhere and only increasing... Who's going to need the most protection? Those who have high exposure to white LED or fluorescent light bulbs in offices and homes, frequent users of LED computer monitors, tablets, or smart phones, and those at risk for AMD, particularly those at high risk, (those with family history, smokers, etc.).

UV-blocking contact lens

Assessing the risks, protection

Given the lack of nailed-down scientific evidence, one has to make a personal assessment weighing the factors. But there are reasonable precautions to take, even ignoring the macular degeneration theory—sunglasses and blue-light-cut eyeglasses in particular.

Many companies are pushing solutions such as eyeglasses with blue-light-cut coatings, so the vested interests involved need to be considered. That said, blue light filtering eyeglasses might reduce eyestrain and this is easy enough to assess for anyone working at a computer for hours every day. Such solutions are thus appropriate to try, particularly if there is any evaluation period offered.

In my personal case, 10-12 hours daily computer usage seems to put me at high risk, which concerns me greatly. However, I don’t know how much blue light my LED computer displays emit, and I have no basis for knowing whether the risk is zero or something very significant.

Nor do I understand if configuring my NEC professional displays to run slightly warm (yellow) would reduce the risk (I would expect it would).

While I wear UV-blocking contact lenses* as well as sunglasses when outdoors, it’s not clear to me that my contact lenses block blue/violet light at all as when using a computer display. If they did so effectively, it would interfere with my assessment of color balance for photographs. So I suspect that I have no protection for computer work using just contact lenses.

* The Accuvue web site states that “UV-absorbing contact lenses are NOT substitutes for protective UV-absorbing eyewear such as UV-absorbing goggles or sunglasses because they do not completely cover the eye and surrounding area”.

I do a lot of cycling, and high quality sunglasses are very important to me. Hiking at extreme altitude is also considerations. At the least, high quality sunglasses are no-brainer for both comfort and eye protection. See my experience report with the Revo Guide S sunglasses at WindInMyFace.com.

Revo Guide S polarized sunglasses, Open Road lens

Change the display

Professional displays offer the option of custom calibration, so that a display can be set to, say, 5000°K instead of the typical 6500°K. This is one solution that should greatly reduce the amount of blue light.

Security: Phishing Email Purporting to be a Password Reset Notification

Playing off the now-common practice of companies sending emails for logins from new IP addresses and so on, this latest type of phishing email is very dangerous.

Do NOT click on links in emails (in general), particularly ones like this.

See also other security topics.

Evil phishing email purporting to be a password reset request notification

NEVER (well, almost never) click on links in emails. Well, almost never; if it arrived right after you yourself requested a password reset—that’s a reasonable case. Otherwise, if you were born yesterday and actually think it is legit, go to the claimed site by entering the web address manually, e.g., apple.com or whatever.

In MPG’s view, Apple Mail is remiss in not adding technology to counter such emails, if only popping up a little display with the URL when the link is moused-over. It’s just insanely discourteous to users that features like that are not there, at least as an option.

Apple’s Time Machine Obliterates my Data When It is Most Needed (Restore)

macOS Sierra 10.12.3.

MPG has long advised NOT relying on Time Machine for a primary backup, and instead using multiple clone backups. It has had bugs before, and I ran into a doozy over the weekend.

I had mangled a bunch of html files as part of a major site overhaul, and I just wanted the top-level folder back as of 12 hours or so prior—that’s the type of thing perfect for Time Machine.

  1. Enter Time Machine.
  2. Restore Folder.
  3. Observe that the restored folder now has ZERO files in it (empty). Time Machine WIPED OUT everything. No error message, no indication of any issue (that folder has had files for many years, and thousands of them).

Given this observed behavior MPG strongly advises not relying on Apple Time Machine. Except perhaps for restoring a file or two due to user mistakes—that at least works well enough.

It doesn’t matter what the explanation is when backup software fails in its most critical purpose (restoring), it must be considered garbage. It doesn’t matter that it has worked for me in other situations (single file restore). That is, it just cannot be relied upon for a primary backup.

Finder Hangs While Copying

macOS Sierra 10.12.3.

Apple’s macOS just keeps getting more and more unreliable, and for basics—Apple Core Rot.

I was just trying to copy about 900 files from one volume to another (both SSDs). The first couple of tries, the Finder hung when most of the way done, as shown. Copying those same files in Terminal (cp src/*.html dest) works instantly with no issues, proving there is no drive problem.

I gave the Finder several chances: first I force-quit it—same problem. Then I rebooted—same problem. In each case, 'cp' at the command line copied all the files in under a second without any issues whatsoever. The rest of the system is totally stable.

This is not the first time I’ve seen Finder file-copy problems—I’ve seen worse issues with silent failures and files not copied—very dangerous stuff. If I had to guess, I’d say some nitwit got his or her threading code wrong and never bothered to write any proper tests.

Isolating/Blocking Hard Drive Vibration, Especially on a Hardwood Desk or Floor

Hard drives (“spinners”) typically rotation at 7200 rpm, and this generates vibration. Placed on surfaces like concrete flooring, this is of little concern. But placed on a hardwood desktop or floor, those vibrations can resonate into the material in a quite annoying way (a low humming vibration typically). Or not, depending on the material. While the enclosure can eliminate much of the vibration, certain frequencies are not attenuated.

MPG has both a hardwood desk and hardwood floors, so these types of vibrations are very unwelcome, hence a search for a solution.

Sorbotthane stick-on bumpers

Even the best drives have some vibration, and if you have 4 or 8 drives in a RAID, it gets worse. If you have a vibration problem, try 1.25 sorbothane bumpers . They work well to detach any vibrating something from a hardwood floor or wooden desk or similar.

Isolation pads

The Auralex MoPAD Monitor Isolation Pads do the job. While designed for audio monitors (speakers) they do a great job of blocking vibrations from spinning hard drives. The pads include wedges that allow the hard drive(s) enclosure to sit perfectly level on desk or floor.

Intel 'Kaby Lake' Processors for MacBook Pro, iMac, MacBook, etc: Already Way Behind the Curve?

Apple released the 2016 MacBook Pro starting in November 2016 utilizing processors that had some limitations, including a 16GB memory limit (or at least that limit given power consumption considerations).

In January 2017, Intel announced many additional new 'Kaby Lake' CPUs. These new CPUs offer more range of power and clock speed options, and some incremental improvements.

B&H Photo already shows a wide range of Intel Kaby Lake PCs.

A product 'bump' might occur in 2017 for the 2016 MacBook Pro, though this seems unlikely until at least June. But it may include a MacBook Pro with a 32GB memory option (!), perhaps as early as June, perhaps as late as Q3. Having 32GB goes a long way towards making the MBP 'pro' again.

MPG advises pro uses to defer purchase of a MacBook Pro if not immediately required. There is not much 'pro' in the current MacBook Pro lineup, the 2016 model being actually slower than the 2015 and 2013 models in some cases.

More likely is a new MacBook relatively soon—hopefully not one crippled again by having only a single USB-C/Thundebolt 3 port.

What’s possible in a laptop?

While Apple dithers and makes a non-pro MacBook Pro, vendors of high-end true professional-grade laptops just shut up and deliver.

It’s just that Apple won’t step up to the plate and do it. Few professional users care about marketing-bozo ideas on reduced battery life or “it’s not pretty enough” rationalizations for pro machines that are really just overpriced dilettante consumer toys. Imagine if a machine of this power were offered by Apple (but with a Retina display and PCIe SSD). It would be snapped up by pros for all sorts of reasons. Which leads us to crux of the issue: Apple does not build computers for professionals any more, hence the odds of getting one are modest at best.

Over at blog.MacSales.com there are some good tips in Tech Tip: Keep Your Electronics Warm During Cold Weather: TEST

Not Sure If It’s Too Cold? Check the Specs

One final word of caution. If you’re not sure whether your device will work outside in cold weather, check the manufacturer specifications. Most specs include minimum and maximum temperatures both for storage and for use, and as long as you keep those limits in mind while either storing or using your device, you should be able to prevent damage.

The new 2016 MacBook Pro with Touch Bar, for example, can be stored in temperatures from -13° to 113°F (-25 to °C), but only used in temperatures between 50° to 95°F (10° to 35°C). An iPhone 7 or 7 Plus can operate in a wider range — 32° to 95°F (0 to 35°C), and can withstand non-operating temperatures between -4° and 113°F (-20° to 45°C).

As I often travel in the mountains where temperatures frequently approach 32°F (and often drop into the teens), the 50°F minimum temperature specification is a bad joke. Basically, most of the year and most of the time I’m in the mountains, the MacBook Pro technically is inoperable, according to Apple. But here’s the thing: once the MBP is warmed up, its internal temperature is much warmer, and it should be fine. So once I heat up the cabin of the SUV, I’m good. Still, it’s hardly instant.

Fortunately most of the time I am working in my SUV when on my laptop, so I can warm it up given a little patience (running the engine and sealing the cabin).

My suspicion is that the operating temperature range is mostly noted for the battery. The polymer batteries that Apple uses in all their devices fail within minutes in the bitter cold.

We routinely use all versions of the MacBook Pro at temps from -10˚ to 30˚ F as long as they are plugged into power source (usually a generator or lead acid car battery). I know, I know… not always available for everyone especially when using a computer designed for portability. Also, when in the cold, I keep a hand warmer rubber banded to my iPhone in the cold and it works as well as on a 72˚F sunny day (hand warmer goes on the backside of the phone against the battery).

MPG: that makes sense. On the other hand my Lupine batteries work fine in extreme cold, and for the Iditarod.

Intel “Baby Canyon” NUCs with Kaby Lake and Thunderbolt 3 and Lots More

Next Unit of Computing (NUC) is a small-form-factor personal computer designed by Intel.

Sorry, it’s too nice for Apple to offer. It needs at least 80% of its features ripped out, so that Jony Ive can design something useless to make it look cool in a product shot. For starters, it needs those cooling vents removed to look cool so it can overheat, along with screws that take a tool no one has, to screw you know who. And memory that is not soldered on? Egads!

When I find myself getting excited about a non-Apple computer, it is proof of just how sucky the range of Apple product offerings has gotten.

I’d love to have one of the Intel Core NUCs as an option for a compact little server. Alas, I don’t want to run Windows or Linux.

The latest Intel NUC offerings have everything I’d want for a mini server or a terrific ultra-compact home computer. It makes the Mac Mini look like the cheap shitty overpriced plastic toy it is.

Now imagine super-sizing this NUC into BUC (big unit of computing) and let’s call it the 2017 Mac Pro. Don’t get me started on rhyming in exasperation with either of those.

If Apple made this product, I’d call it insanely great. But Apple doesn’t, because Tim Cook probably thinks the Mac Mini is a great desktop computer because it is a shitty non-upgradeable cheap white semi-sealed plastic toy.

Seriously, if Tim Cook allowed this NUC to be made, fools like me would buy one for $500 more just to run macOS Apple Core Rot™ on it. Read it and weep.

I have a NUC running VMware ESXI at home. I had to break the Apple EULA to run OS X VM's on it, but with 500GB internal and 500GB USB3 SSD and 32GB RAM, I have four VMs running with free backup.

I could have put an old MacPro in at home, but the power usage is silly compared to the NUC. They're great little machines.

MPG: the acronyms alone make this a challenging proposition, let alone violating the EULA and dealing with the complexity and risk of future macOS breakage—but it might be worth it for some.

Checking drives before putting into “production”

diglloydTools

See also Even ”Enterprise Grade” Drives Fail.

According to Tim Standing of SoftRAID, initial verification of a drive can preclude a large percentage of relatively early drive failures.

While SoftRAID has a certify command, it does not graph the performance, and so I would add this point: in my experience, drives that show aberrant behavior are also more likely to fail, even if they pass certification.

The diglloydTools DiskTester fill-volume command can test 99% of the drive and graph the behavior, as shown below, where 5 samples were tested simultaneously, and then graphed together to verify consistent performance—important for RAID setups.

Over the years I have found that aberrant performance behaviors (obvious in a graph) are often an excellent predictor of flaky drives. The test-reliability command is good too, with the major benefit of being able to operate on in-use drives—no need to take a system down for days to certify (which means having to completely wipe) the drives.

Show below is drive performance for five samples of the HGST 8TB Ultrastar He8 hard drive. All samples deliver the same pattern of declining performance as the drive fills up—exactly as expected. Drives with excessive remapped sections tend to show weird spikes in speed in the wrong places. This is bad for RAID performance as well (when drives do not perform the same in the same area).

Lifespan of Uninterruptible Power Supplies (UPS)

Get APC UPS at B&H Photo.

A bad smell developed in the garage, where I keep a couple of servers running on uninterruptible power supplies (UPS). Two batteries, each weighing about 75 pounds, are daisy-chained for extra “juice” off an APC SmartUPS 1000XL. I do so because I’ve had power failures up to 24 hours.

Both of the add-on batteries had leaking battery acid, or rather, signs of it having leaked such as white powder and blackened wood under the units and what looked like fluid on the plastic casing. I disconnected them and set them aside for the next hazardous waste day.

UPDATE 18 Jan: APC tells me that the add-on batteries were from 2005. I’m skeptical since that’s the year I started my business and I don’t think I bought 150 pounds of batteries way back then, but that’s the claim. If true, the batteries were way past their lifespan. But the APC SmartUPS 1000XL gave no warning or indication of a problem.

The main unit with the “smarts” to which these batteries were daisy chained does not appear to be leaking, but its battery is now over 3 years old. The unit is running hot even at an ambient temperature of 40°F, and the charge lights show only about 80%, so it is done-for. These things should never get even warm under such conditions, so that battery is surely toast.

This is not the first stinky leaking battery problem with APC; I had this happen just as I was leaving for a trip last summer. That time, the battery had bulged so much that I had difficulty extracting it. I gave up and it went to hazardous waste disposal.

Maybe this is my fault: after all, lead acid batteries have a limited lifespan. But the fact that the APC unit cannot detect such potentially serious failure situations is disappointing and calls for taking care to assess the health of any UPS on a regular basis (3 months is probably about right).

I’m probably going to pick up a new APC Smart-UPS 1500VA with LCD and Audible Alarm Disabled, which has pure sine wave power when when running on battery power. It can also take additional monster batteries which plug into the rear of the unit, for extended runtime.

Tips:

  • Check your UPS battery every few months for signs of leakage: put an appointment in your calendar to check.
  • If the UPS is running hot, there is a very good chance the battery is bad. It could leak or rupture and cause damage. A fresh UPS does not run hot (once fully charged), since it is just bypassing current to devices.
  • Use a marker to write a date onto the battery itself, as shown.

I have used replacement batteries from this source of several years now. My backup demands are not as demanding as yours, but I have used several replacements from this firm that have served me well.

Below is the link to the APC RBC7 battery mentioned in Don H's reply to your post.

http://www.batteryspec.com/cgi-bin/cart.cgi?action=link&product=182

The listing of replacements for all APC UPS Systems:

http://www.batteryspec.com/html/apc-ups-replacement-batteries.html

This company has been in business for > 30 years so they are not a flash in the pan. Substantially less expensive than APC replacements as well. I’m sure you know more about the technology behind these batteries than I do.

You might take a look. No relationship with the firm: just a satisfied customer.

MPG: I’ve been leery of 3rd party batteries, but the prices above are far lower. But this site has way more brains to their approach: a listing showing UPS models and their batteries. It is WAY better than the APC site. Also, it's about 30 miles from me. I’m going to see if I can just drive down their and get things swapped out.

One thing APC *does* include is free return postage for disposing of the old one. I know little about the issue; I’m just a customer who doesn’t want an exploding or leaking battery. And since 3 (actually 4) APC batteries have leaked or bulged in the past year, I’m open to credible alternatives at a lower price.

Don H writes:

In the 1990s I worked for a growing company and had to spec out a UPS large enough to support five servers for a six-hour outage. At the time APC had the best modular system, so we bought that and it performed well. This was back when Cisco’s product line only had three basic models of routers while Apple had a sprawling product matrix with far too much overlap among machines. (We called that phenomenon ‘Spindlerization’, due to Mike Spindler’s penchant for trying to match the PC world model-for-model.)

Over the years I have bought and used APC UPSs for personal use, but noticed that they too expanded their product line to the point that one can no longer navigate it. (Meanwhile, Apple famously managed to rein in their own product line.) One consequence of this lack of cohesion is that many UPSs became orphaned because the batteries were no longer available, or became so expensive that it was not economically feasible to buy a replacement battery for almost the cost of an entirely new unit. And this is what irritates me about a lot of companies: the changes made to the parts are all just different enough to thwart cross-product or backward compatibility, yet the changes are not significant enough to provide any functional benefit.

Sony did this with their consumer electronics power supplies (it seemed like every new product changed the charging connector and power brick.) Wristwatches (remember those?) have a battery variety that fills fat books. Samsung’s entire business is a pathological example of change for the sake of change. (I have no idea how their service department handles it all, partly because I will never buy a Samsung product.)

I have discarded otherwise functional APC UPSs because it was too frustrating to chase down replacement batteries. The last time I looked, their web site was a mess*. Because of these practices I have written them off - APC is dead to me. Other UPS companies have similar, but not quite as acute disorganization, but I haven’t had the bad experience (yet?) with other brands that I have with APC.

Well, crap. I just looked at Tripp Lite’s product line. That’s 279 different models, each with one insignificant feature different from a dozen others.

I guess it’s better to have an embarrassment of riches rather than nothing at all, but I am personally getting really tired of hacking my way through other companies’ wasteful lack of focus or product cohesion. Your post on APC just happened to trigger this particular rant.

* Ok, I just looked again and the first thing I see at APC is an ad saying “Want to turn APC products into Recurring revenue?". I know the intention is to sell ‘managed services’ but my immediate interpretation is that they have figured out a way to milk their own customers with post-sales water torture costs.

But I stand by my complaint about their ridiculous product line. I would be willing to bet that they now have three or four hundred UPS models just in their Back-UPS and Smart-UPS categories, and that’s not getting into their enterprise ’solutions'.

MPG: indeed, it is a very confusing product line with hundreds of options.

I spent 20 minutes trying to find the right internal replacement battery for the SmartUPS 1000XL (it is not listed in specifications or data sheet!). I am pretty sure that the right replacement for the APC SmartUPS 1000XL is the APC Replacement Battery Cartridge #7, RBC7. I did find the external add-on battery supplement page.

APC sucks in a lot of ways: the web site can be extremely slow, it is very hard to find the right battery (and no distinction between internal and external). Tech support inquiries require serial numbers—well it’s not see easy to get a serial number when a 50 or 75 lb device is in a tight space that does not make it visible. I might look at TRIPP LITE and see how that goes because evey time I have to deal with battery issues it chews up hours.

Bill Atkinson’s “Photo Card” for iPhone/iPad: Tangible Internet-Age Postcards

Bill Atkinson is Mr. Hypercard, of Apple fame. He is a color expert and brilliant photographer. Today I had the pleasure of his company on several topics, including his latest creation.

Bill showed me his latest creation, the iPhone/iPad app “Photo Card”, available on the Apple Store. Other platforms are coming, e.g., Android, and I am trying to persuade him to do a web interface for computer users like me.

It started simply enough—Bill showed me one of his postcards—printed and sent through the mail. The card is very durable and aside from holding it to see sheen to reveal the printed-on postal service processing stuff (or a UV light), it looks like it was just custom made and was never posted.

It’s the kind of thing you could not do half as well at home: I was astounded at the quality of the laminated card with excellent color. They’re way more good enough to frame—and no backing/support is needed in a frame so you can see front and back of the card. backing/support is needed in a frame so you can see front and back of the card.

How it works

First, you need to create an account and buy credits.

You choose your own image, your own stamp, and you can even add a QR reader for a voice recording. Very slick, very well thought out. For example, just entering the zip code alone looks up the city and state, saving time on addressing.

A preview after editing is shown below. The fish picture (mine) will be the front of the postcard. The stamp is a real postage stamp made with my own image, the bike is a graphic just for fun, the smaller fish picture is yet another picture of mine, and the yellow/blue thing will contain a QR code with a recorded voice message up to a minute long.

Two things from my POV: (1) the images have to be on the phone to be used by the app, which for me means copying and syncing to the phone first—a hassle. This is of course NOT an issue for shots made with the iPhone and already on the phone. (2) I would like to make cards on my Mac in an app or web browser because it is far more efficient for me to work on a computer, where all my photos and contacts are stored.

Adobe Memory Usage, with no apps in use

See my Mac wish list.

Earlier today I wrote about macOS BloatWare.

Adobe Memory usage with no Adobe apps running

Now it’s Adobe’s turn to be spanked: I take a dim view of products using substantial memory when absolutely nothing is running.

These Adobe processes are just there running all the time even when no apps are in use, and they take up 132MB of real memory. On 4GB or 8GB machines, this is not a trivial consideration and if every vendor did this, pretty soon a GB or two of memory would be scarfed up to no useful purpose.

Adobe ought to have one bootstrap daemon using at most 10MB, one that can fork off all this overhead cruft when an app is actually in use. As shown, memory usage rises to justa bout doubles for these overhead processes when an Photoshop is in use—a huge amount for what is likely a very basic task.

macOS BloatWare (and what feels like SpyWare)

See my Mac wish list.

Recently I’ve found that Photoshop CC 2017 on macOS 10.12.2 will no longer complete the diglloydMedium benchmark in 16GB of memory without a slowdown—compare 2013 results to 2015 results to 2016 results—the trend is substantially slower at present. What I observe here in 2016/2017 is a lot more memory swapping, which necessarily slows down the test.

So something has bloated in the system to push it beyond the point at which 16GB is adequate, causing that memory swapping: (a) the benchmark runs as fast in 2016/2017 as it did in 2013 when enough memory is availble and (b) Activity Monitor shows lots of swapping going on. See 2013 Mac Pro results, which show that time to execute in 2013 is within 1.1% of the 2016 figure. Ditto for the iMac 5K — but both have 64GB.

I think it likely that the slowdown is mainly due to a bloated macOS memory footprint, though I cannot rule out Adobe getting sloppy witih a lot of memory usage overhead.

We don’t have to look far for seriously bad software design: here is macOS Finder using nearly 5GB of real memory. This is a design obscenity, given that Apple sells a lot of laptops with 8GB total system memory.

5GB memory usage by macOS Finder

Why does all this stuff run that I do not want, some of which I have even turned off?

All of these processes consume memory and at some point, consume CPU time.

I was looking through running processes and wondering how much crapware and bloatware I might find. But off isn’t actually off in some cases, like Siri.

Qué Siri, Sera isn’t an acceptable answer. All of these were running on my 2013 Mac Pro, all take memory and none of these processes offer functionality I want active. Some like “CallHistoryPluginHelper” raise privacy concerns, and that’s not idle speculation.

Use "sudo launchctl list" to list active background processes. Alternatively, one can select all in Activity Monitor and copy/paste as plain text, but the two lists use different names for some processes.

The list below reflects turning off everything that I don’t want that macOS allows to be turned off, so the actual list for most users may be significantly larger/longer. As well, there are more daemon processes running than just these.

MacOS X, I will remain on Yosemite, has always been full of bloat and it is deteriorating fast and steadily.

SIP making it even harder to find the necessary ticks and switches to be halfway back in control of your own machine.

With 16 GB RAM in my MacBook Pro the system eats 25-30% of RAM after a cold boot just idling in Finder.

Deleting or unloading all those services is in my eyes a must. There are daemons active that are meant for features that aren't even supported on my hardware. Airdrop, anything iphoney, like handoff, cloud-nonsense: the lists just keeps growing.

After going through all these launchctl agents and and demons (sic!) – that are sorely lacking in documentation; just to add insult to injury – I am now happy about a system that 'just' eats away 10-15% RAM at idle. That is about half of both RAM-sticks the machine came with.

Of course you have to avoid Mail.app and Safari, Contacts and just about anything that Apple chose to bundle. They are mostly useless or downright dangerous for my data.

Then try to look at what cfprefsd does, writing plist files into your user preferences directory every minute for things like Dock and Finder that only are in use. Not changing anything in there respective preferences. coresymbolicationd's data directory, coreduetd's /var folder (Even when it was never used, never was supported on my machine, it managed to accumulate 5 GB of worthless data when I found out about it.) The always growing out of hand and often self.corrupting cache-files, etc. The only example I know of that actually got better from 10.9 to 10.10 was /private/var/log/asl keeping itself in manageable and sensible proportions in Yosemite. Keeping in mind that there are now even more examples of these crazy writes to disk one keeps wondering if this is equally detrimental for ssd's as the recent Firefox-session-store 'scandal'? Once set up I rarely change prefs in my apps. And yet. Cfprefsd writes 10 GB a day 'for me' and this is untenable _and_ untameable.

So I keep asking myself and now I am asking you: For how long will you remain in this sinking boat and swallow all those salty drinks Apple keeps serving us?

Come WWDC security updates for Yosemite will stop. If they announce a single new feature instead of a very, very large list of grievances fixed along with an apology for all those crazy stupid design decisions of the past years (starting with .DS_Store), then I will jump ship.

MPG: the natives are getting restless.

Constant writes to disk are a source of wear and tear on SSDs; the flash cells on SSDs can be written so many times. Writing 1 byte or ten is the same as writing an entire 512K block (of flash memory). It is perhaps an argument for never booting off an expensive SSD, just to avoid the constant write-harrassment of the SSD by the OS.

The GPU remains a Science Fair Project

See my Mac wish list.

Update 10 Jan: Adobe contacted me (well, I sent a link to this post to Adobe!), and they are going to look into the crash I'm seeing. I have provided an actions file and script to drive it. Now if only they would also agree to do something to address the GPU scaling headache.

Three+ years ago, the 2013 Mac Pro was released by Apple with graphics drivers rife with bugs. It took 6 months to get the drivers to a usable state. Adobe actually added GPU support for sharpening, then had to take that support out. What I never understood is how Adobe could ship those code changes without proper testing, the proof of that being self evident in the undoing.

Graphics driver bugs caused by half-baked Apple code are one thing—and I do pin the lion’s share of the blame on Apple. [It is my understanding that AMD engineers actually developed the drivers for the Mac Pro, but it’s Apple’s responsibility to ensure quality control.]

GPU problems with Adobe Camera Raw in Photoshop CC 2017,
macOS 10.12.2

But graphics driver bugs aside, Adobe could at least address what it can, that is, Adobe fails to fix severe usability bugs that result from enabling the GPU—for over two years now. Adobe was/is well aware of this issue, because I communicated directly, the issue was acknowledged as “hard to fix”. But even though I suggested minimally invasive user interface changes that could at least sidestep the scaling problem, this was not done either. Well, what is the point of a GPU if it results in unreliable operation of any kind?

And now GPU bugs persist to this day and now have taken a turn for the worse.

With the release of macOS 10.12 Sierra and Adobe Photoshop CC 2017, Photoshop has become more unstable than it has been in years. My 2013 Mac Pro, 2013 and 2015 and 2016 MacBook Pro and iMac 5K all have shown this GPU problem, as shown. Not always, but at launch or other times, and often enough to be disturbing.

Just today, something hard-crashed my Mac Pro (hard power off required), an extremely infrequent event (months without such a crash)—I was using Photoshop/ACR. I suspect the crash was a GPU driver crash in kernel space.

I don’t know where the fault lies (Apple or Adobe), but it is pathetic that one of my test suites (Lens Filters) cannot be completed on any Macs reliably, and never can run successfully on 2 of the 5 Macs.

I just upgraded my 2013 Mac Pro to Sierra over the holidays while I had down time.

I’m using an AJA LHI through ThunderboltBox and Final Cut X 10.3.1. I am getting kernel panics now (must be around a dozen).

I’m suspecting a driver issue of some kind – and your GPU thoughts have me leaning to look more in that direction. Maybe the next OS update will help. I should never have updated. So frustrating!!

DIGLLOYD: frustrating indeed for professionals trying to get work done. A kernel panic is of the same bug level as my 'hard freeze' I reported: something nasty happening at a level that kills the operating system.

Martin writes:

I read all your articles, and especially the more nerdy stuff about apple. Normally most of the people writing about Apple have nearly no clue about this more nerdy in deep stuff.
but I have to say something about your GPU disillusionment.

I’m into this GPU stuff since the late 90 doing 3D visualization and animation with extremely special and expensive cards, GPU acceleration before it was on the mass market.

And people like me know all these weird problems you experience.

It may sound bold and offensive but the 2013 MacPro with AMD GPUs and Adobe is the worst possible scenario. AMD drivers are known from the beginning as not suitable for professional work, besides they always had this FireGL pro line.

When you’re lucky that the drivers are stable, you will somehow experience display or rendering (calculation errors), especially working with fine graining values or extremes.
This is the reason nearly every pro in the 3D business or doing extreme compositing / video stuff is equipped with NVidia cards. The bad thing, the quality of their drivers is declining. In most of the pro software products is CUDA better integrated, integrated at all, more stable and a lot faster.

AMD looks always sweet on the spec sheet but they never deliver these speeds or stability. And the last 20 years there was never a stable and bug-free OpenGL driver from ATI/AMD, they are known for bad OpenGL.

The bad stuff, a lot of Adobes GPU implementations are also founded on OpenGL, like Lightroom's develop module - ADOBE confirmed this official that LR uses OpenGL. So every Mac now with a DGPU has an AMD GPU. Adobes Mercury Engine also relies on a lot of NVIDIA stuff - Premiere renders x times faster on a GeForce — is there is now other problem - ADOBE’s GPU implementations are really bad - MEDIAENCODER loves to show it uses CUDA but renders on your slow CPU.

But there are other software companies who have working GPU code - like Phase One. Run Capture One Pro on an 5 year old Intel i5 PC with a cheap GTX 970 — this is so much faster than Lightroom on the most badass Mac or PC money can buy. But Phase One also suffers from bad AMD drivers on Mac Mac and PC—just take a look and their user forums, a lot of people mourn that the software is so slow on their newest hardware.

At the end it relies on the software and Apple is constantly kicking us pros into our balls with their decision not to use NVIDIA.

MPG: the survey at BareFeats.com shows that 80% want NVIDIA cards, not AMD.

Crapware in macOS

See my Mac wish list.

I just thought that screen shot below captures the hubris run amok at Apple: the disregard for users that manifests itself at every level of the software and hardware product stack.

Crapware that I cannot remove is a dissatisfier (applies to iOS also), whether it is Chess.app or Garbage Band (oops, did I mis-spell it?) or the other Apple apps I never use and never will use.

Chess.app is a required application in macOS Sierra

On a related note, I have turned Siri OFF. The arrogance of Apple running the Siri process anyway is part and parcel of the attitudinal problem.

macOS: Siri runs even when off

When Siri is off, it’s still running. Any attempt to disable it in the plist is rejected by special security privileges that cannot be bypassed.

Can a 2016 MacBook Pro support an 8K display?

See my Mac wish list.

The Dell UltraSharp 32 Ultra HD 8K Display will hit the market in early spring, raising the question of whether any Macs can drive that glorious 33.2 megapixels.

The GPU power along with the bandwidth required to drive four 4K displays is just emerging, but the 2016 MacBook Pro looks like it might be capable enough.

Apple specifications for the 2016 MacBook Pro state:

Up to two displays with 5120-by-2880 resolution at 60Hz at over a billion colors
Up to four displays with 4096-by-2304 resolution at 60Hz at over a billion colors

A 4K display is 3840 X 2160; thus four displays at 4096 X 2304 offer 13.7% more bandwith than required to drive an 8K display. Of course, an 8K display would have to be the only display, unless a 2017 Mac Pro arrives that can drive six or eight 4K displays. But with a MacBook Pro, presumably the internal display remains usable, so a dual display system looks possible.

Using two Thunderbolt 3 cables, it should be possible to drive an 8K display on the 2016 MacBook Pro in 10 bit color*, at least in terms of the required bandwidth, using a trick similar to how a 5K display was possible in previous Macs: drive each half of the display with one of the Thunderbolt cables, that is, Multi Stream Transport. The same trick might work for 8K. Perhaps Apple or Dell will weigh in on this possibility soon.

* The Apple specifications indicate “billions” which means 10-bit color.

Potential for an iMac 8K

Since a 32-inch 8K panel now exists, and the 2016 MacBook Pro already has the bandwidth to drive an 8K display, an iMac 8K is technically possible with today’s technology.

An iMac 8K could use a custom graphics solution to push those 32 megapixels, just as the iMac 5K does. There is no need for wait for standards to evolve to support external 8K support; it can be done internally with a proprietary solution. The main issue is cooling, but Apple should be able to engineer an appropriate GPU cooling system. And since the 2016 MacBook Pro is an even greater cooling challenge, and it can drive four 4K displays, it hardly seems like an iMac 8K should have any barriers to supporting an 8K built-in display.

The Dell UltraSharp 32 Ultra HD 8K Display will apparently sell for $4999. Even assuming that Apple could use its considerable volume to get that price down to $2000 or so, it would make an iMac 8K with the necessary GPU power something hitting the $6K to $8K range in price. So even though it appears to be ideal for an 32" iMac 8K, cost is likely to push off such an iMac. Then again, Apple has surprised us in the past, and could do so again, particularly with its failure to innovate for several years now.

Dell UltraSharp 32 Ultra HD 8K Display Suggests that an iMac 8K is Technically Feasible

See my Mac wish list.

See also Too-High Pixel Density on 5K and 8K Displays Impedes Image Assessment.

While I saw firsthand the LG 5K display for the 2016 MacBook Pro, unfortunately I did not chance upon the Dell 8K 32-inch display which was announced at CES.

7680 X 4320 pixels = 33.2 megapixes in 32" form factor, aspect ratio 1.77:1

A 4K display is like tiling together four HD displays and thus requires 4X the bandwidth of a conventional 1920 X 1080 display. An 8K display is like tiling together four 4K displays for a whopping 33.2 megapixels (7680 X 4320).

A a full resolution Nikon D810 image is 7360 X 4912, so its entire width fits with room to spare on an 8K display, although the aspect ratio is too tall to fit vertically. The pixel density of an 8K display has to be an awesome viewing experience, but high pixel density is problematic for assessing image sharpnesss.

The $4,999 UP3218K is slated to go on sale on March 23rd. It has a refresh rate of 60 Hz and will work with zero Macs and only a few select PCs with specialized video hardware, and even then GPU performance will need some time to catch up. The display supports 100 percent Adobe RGB, sRGB, and Rec709 color gamuts.

HDMI 2.1 (announced at CES) supports 8K, but Apple doesn’t even support HDMI 1.3 yet, so external 8K displays are likely to take a few years to become more than a special rarity.

However, at least in bandwith terms, 8K might already be possible; see: Can a 2016 MacBook Pro support an 8K display?

Potential for an iMac 8K

Since a 32-inch panel now exists, it seems ideal for an iMac 8K which could use a custom graphics solution to push those 32 megapixels—no need for wait for standards to evolve to support external 8K support; it can be done internally just as with the iMac 5K.

The Dell display will apparently sell for $4999. Even assuming that Apple could use its considerable volume to get that price down to $2000 or so, it would make an iMac 5K with the necessary GPU power something hitting the $6K to $8K range in price. So even though it appears to be ideal for an iMac design, pricing is an obstacle that could put off an iMac 8K for a year or more.

Yes, you want one. It looks fantastic in person, shot below from CES. But at present it works only on the 2016 MacBook Pro, via a Thunderbolt 3 cable, as shown below. OTOH, for about $1700 you can get a 5K display from Apple with a free computer.

I am NOT recommending it for work where evaluating image sharpness or very fine tweaks is needed—that’s why I still use the NEC PA302W for my image evaluation—the pixel density is way too high for that type of detail work. But like the iMac 5K viewing experience, the LG 5K is aweseome for viewing images, with its 14.7 megapixel display.

I did not chance upon the Dell 8K 32-inch display which was announced at CES, but a 32-inch panel now exists, it seems ideal for an iMac 8K which could use a custom graphics solution to push those 32 megapixels. An 8K display requires the bandwidth of four 4K displays and isn’t going to fly with any Mac (yet).
