With the Delay of Apple M1/M2 Pro Macs, What to Do Now?

re: Apple Readies new Crop of Pro Mac using Apple M1/M2 Chip Technology


The recent Apple WWDC event failed to produce any new Macs, and the latest thinking is that some models will be delayed as late as next year. It’s guesswork, since Apple famously declines to pre-announce.

Waiting a few more months may prove fruitful for those looking for a new iMac 5K replacement and/or Mac Pro replacements.

For those who need something with some 'grunt' in the immediate term, my #1 recommendation would be the 2020 iMac 5K with the following key specifications. A Mac Pro of similar configuation is also an excellent choice.

The Thunderbolt peripherals will work with Macs and PCs, Intel or Apple M1 processors.

Apple Readies new Crop of Pro Mac using Apple M1/M2 Chip Technology

UPDATE June 16: looks like we’ll have to wait quite a bit longer, perhaps even 2022, at least for laptops.


Bloomberg is reporting that Apple is readying a new crop of improved and higher-end Macs based on the Apple M1 CPU technology. Highlights, according to Bloomberg:

  • Mac Pro M1 with 16 or 32 high performance cores (and 4 or 8 energy-saver cores), and 64 or 128 GPU cores.
  • For the MacBook Pro lineup, 8 performance cores (double the current number) and 2 energy efficient cores.
  • Up to 64GB memory in the pro laptops.
  • Improved Neural Engine.
  • 4 Thunderbolt/USB-C ports on the pro models and a rumored new Mac mini.

If this pans out as claimed, it looks like even the fastest souped-up PC will be left in the dust. And my my 2019 Mac Pro 28-core looks to be a dinosaur this year in terms of performance.

OWC has outstanding peripherals for current Macs and these new ones. See my various OWC wishlists for storage, SSD, etc.

Apple Readies MacBook Pro, MacBook Air Revamps:

...The overhaul encompasses a broad range of Macs, including Apple’s higher-end laptop, the MacBook Pro; the laptop aimed at the mass market, the MacBook Air; and its desktop computers, the Mac Pro, iMac and Mac mini, according to people familiar with the matter.

Redesigned MacBook Pros are expected to debut as soon as early this summer, said the people, who requested anonymity to discuss an internal matter, followed by a revamped MacBook Air, a new low-end MacBook Pro and an all-new Mac Pro workstation. The company is also working on a higher-end Mac mini desktop and larger iMac. The machines will feature processors designed in-house that will greatly outpace the performance and capabilities of the current M1 chips, the people said.

...Codenamed Jade 2C-Die and Jade 4C-Die, a redesigned Mac Pro is planned to come in 20 or 40 computing core variations, made up of 16 high-performance or 32 high-performance cores and four or eight high-efficiency cores. The chips would also include either 64 core or 128 core options for graphics. The computing core counts top the 28 core maximum offered by today’s Intel Mac Pro chips, while the higher-end graphics chips would replace parts now made by Advanced Micro Devices Inc.


MPG: the only thing that concerns me is the 64GB memory thing, but maybe an iMac or Mac Pro will offer 128GB or more.

Reader Comment: sticking with Mac vs transitioning to a PC

Reader Albert L writes:

I understand that this may be contrary to your current commercial/economic interests, but I’d like your take on the tradeoffs of switching from a Mac to a PC, and/or if you know where I can find information on the subject. There likely are other readers of your MacPerformanceGuide who, like me, would appreciate learning your thoughts on this.

With the introduction of the new iMac, it’s obvious that Apple is shifting from producing useful creative tools to producing cute, mass-market, media-consuming toys:


I currently am using a 2010 Mac Pro with dual 3.46 Ghz 6-core Intel Xeon processors running High Sierra (Version 10.13.6). To upgrade to Mojave, I’d have to replace the current graphics card (ATI Radeon HD 5770 1024 MB) with one that is Metal-capable. Apple no longer supports High Sierra and will stop supporting Mojave on November 30, 2021. It thus doesn’t seem to make sense to spend $300+ on replacing the graphics card.

My 2010 Mac Pro has 22 TB of internal hard drives (8 TB, 8 TB, 3 TB, 3TB), two 240 GB SSD’s on an internal PCIe card, and 96 GB of RAM with another 32 GB waiting in the wings. An additional 36+ TB of external hard drives are on a variety of FireWire 800 and USB 3 enclosures and docks.

“Upgrading” to the 2019 Mac Pro and Big Sur (or later) would kill a lot of my costly (and very useful) peripherals and software (much of which is 32-Bit) and I’d have to replace them.

Before I go through the hassle and expense of doing that, I want to learn as much as I can about what I’d gain and lose if I spent the same amount of money on switching from a Mac to a PC.

In view of your refreshingly honest practice of pointing out the worms in Apple products, I'd appreciate learning your thoughts on the subject.

MPG: if all you do is sit inside Photoshop or similar programs, it could make sense. And it could make sense for certain specialized situations. But in general, soon the next generation of Apple M1 CPUs should blow away the fastest PC performance. So if the argument is about price/performance, I’m not buying it for any general usage case.

Yes, the current M1 Macs are shiny consumer objects that won’t please us pro users, but the performance and glitter will delight the target customer base, just like iPhones.

But when an iMac 5K/6K with double the performance cores and at least 64GB memory support arrives, I’ll be a buyer. Even though I’d prefer not to buy anything at all from Apple. In life, one has to choose among least offensive solutions.

What would switching involve?

The hardware cost is all but irrelevenat: for most users, the biggest expenses is the one of having to relearn things. For the single-application user, that’s seemingly not an issue. Now go figure out what anti-virus to use, how to backup, how to configure mail, and 50 other things you’ll have to relearn, new apps and tools you have to discover and learn. Then you’ll find 20 things you miss. What was gained, exactly? Except a lot of unnecessary work.

For me recoding scripts and tools would mean months of headaches and a shit-ton of work and aggravation. All the dozens of little time savers I do would need reinventing.

I would never recoup 1% of the time and aggravation of switching to PC.

Taking one of the smallest things: just having to deal with a "\" instead of a "/" and drive letters instead of paths is a cloud of mosquitoes for someone used to Unix like me—even keyboard habits have to be relearned. Unix shells don’t solve everything. The irritation of a half-assed 1980's system would never go away; it would be a permanent hair shirt.

There are so many headaches with PCs you'll just be trading one set of aggravations for a larger and more troublesome set. Those who claim it’s better invariably have lower expectations and selective attention along with a dash of cognitive dissonance and confirmation bias. Oh, and then there is the virus scene.

MacOS has lots of issues, and I bitch about it because it impairs my work. But Windows is no garden of eden.

Garden paths can lead to swamps. And greener grass might be astroturf.

Reader Comment: MacBook Pro running OSX 10.12 has finally had the discrete GPU die... used this machine almost continuously for 10 years

Reader Paul W writes:

My 17" MacBook Pro running OSX 10.12 has finally had the discrete GPU die for the final time. I used this laptop to drive 3 external monitors (1 x 27" imac as thunderbolt display, 1 x hdmi via owc thunderbolt 2 doc, 1 x usb->htmi connector). As well, it had 2 2TB SSD drives installed.

I used this machine almost continuously for 10 years and the death of the GPU is like having both my arms cut off.

Short term, I was able to disable the GPU via these instructions: (http://dosdude1.com/gpudisable/), so I can boot up and use the computer with the laptop display with the integrated graphics, but plugging in the Thunderbolt Dock causes the machine to reboot. Not unexpected as it is trying to use the dedicated GPU.

I'd say that getting 10 years out of that laptop with a known hardware design fault is still quite impressive, but going forward, it's going to be a little tough to choose.

I think I'm now down to two possible choices:

1/ upgrade the 2013 27" imac that I previously used as a display only to be an actual work machine (ram, ssd and possibly cpu). I'm even considering moving the main ssd from the 2011 mbp into the 2013 imac. I think I'll clone the drive and test to see whether it will boot properly.

2/ purchase a refurbished 2015 mbp from OWC. I currently have a refurbed 2015 mbp from OWC, but I've got it comfortably set up at home, and I don't want it to travel and risk damaging it anymore.

Buying a new MacBook Pro is out of the question. I am not thrilled with their unrepairable/un-upgradeable design approach, nor will I want OS newer than 10.14, 10.15 installed. Heck, 10.12 ran perfectly for me and allowed me to use my older creative suite software.

Anyway, just weighing my options at the moment.

Thanks again for all the info you share at macperformanceguide.com. The pain you share is the pain that we can choose to avoid.

MPG: when a macOS “upgrade” becomes a disincentive to the point of dissuading purchase of a new laptop, isn’t something really wrong with the evolution of macOS?

Maximilien Z writes:

You can do gpu reballing, it worked on my 17”, it is about “cooking” at a certain temperature the GPU. https://www.youtube.com/watch?v=Gmny86gll-c

MPG: I have no way of evaluating whether the repair works most of the time, some of the time or rarely, and no time to look into competing claims—readers on on their own here. But maybe a repair shop willing to guarantee its results in writing could be worth a try.

There are other videos on the topic and how to try it yourself. Complete disassembly required in all cases and the idea is the same: get the solder “balls” off the GPU and mount, then use fresh solder.

Wolfgan O writes:

I just read your reader's email about his blown GPU in the 2011 (I assume) 17" MBP.
I have the same MBP and had the same problem twice. Reballing is not a long-term solution as the GPU has often been damaged.

I don't know where your reader is located. But there are companiess like Louis Rossman in NYC. https://www.rossmanngroup.com/

Louis also has a great Youtube channel where he teaches his technique:

These guys have the knowledge, the equipment and the parts to replace the GPU. And the price is reasonable if you want to keep using your Mac. I had the GPU replaced twice in my computer. First time was in 2015 and the 2nd time was in 2020.

So mine lasted for five years and when it blew for the 2nd time i had it repaired just because I had such a productive time with the it in the past years.

As a replacement, I would not only recommend the 15" MBP from 2015, but also the late 2013 and 2014 models.

If you are planning to install Mojave for example, then you are out of luck with the 2011 models with discrete GPU, as the afore mentioned “dosdude1” explains:

Just wanted to share these infos in hope they help others.

DIGLLOYD: good advice above, I’d think: lots of work in volved, might as well put in a brand-new GPU chip.

However and without disagreeing, I don’t understand how a damaged GPU can work correctly and then fail other than the idea of it being weak and subject to failure.

Reader Comment: Avoid “Upgrades”, Stick with What is Proven

Reader Jose S writes:

Just to add my two cents to your endless list of issues with MacOS and Macs in general. I've been using Mac computers since the very appearance of MacOS X. OS upgrades were not frequent and they costed money. Upgrading was a no-brainer: it just worked. I did that until Lion appeared. It looked very nice and it promised a lot of UX functionalities that seemed useful. And the upgrade was not expensive. I bought it. It was a mistake. My first MacOS system crash screen appeared with Lion. It was the dreaded MacBook Pro Graphic card issue that was never recognized as such by Apple. They always did the same: logic board switch (charging for it, of course) and never recognized it was a software issue. "Downgrading" to Leopard did the trick for a while until software stopped being compatible. Bought a new MacBook Pro.

Found this site. Understood I was not alone. Since then I have several rules that I've either learned from this site or this site has reinforced:

1- Backup often. Do not trust backups. Verify them as often as you make them. I use Integrity Checker. It was worth every penny. Thanks for that.

2- Never upgrade your MacOS unless you really need it. There is no "6-month delay". There is no "1-Year delay". Just don't unless you can afford to lose your workstation stability and eventually spend days trying to go "back to normal"

3- If you MUST upgrade because your software does not support your current version anymore, do so trying to stay at least one version behind. There is a corollary to these two rules put together. DO NOT use Apple software unless absolutely needed because they force you to "upgrade". If you need Apple software you should seriously think about putting it on a separate machine. Believe me, it's worth every dollar you spend in that double setup.

4- Do NOT buy AppleCare for your everyday machine (assuming you don't "upgrade" unless you absolutely need it) AppleCare used to be a must for me before Lion. Now it's a waste of money (lots of money) and you have absolutely no guarantee it will solve your issues when you eventually have them.

5- Do NOT buy the latest Apple hardware for your everyday toaster. Go for the second-hand market. Go OWC for used Macs. They have better deals and you will save a lot of money to follow the last part of number 3.

My current setup consists of a 2015 MacBook Pro (for work) running Sierra ("low Sierra") and my personal 2011 MacBook Pro (which I call "the last real laptop Apple made") running Mavericks and using Data Doubler and VMWare Fusion to run several Windows and Linux VMs for software development. First-generation Mac Mini for media server running Leopard. Never upgraded. I don't plan to buy anything new from Apple until my current machines die, and in that case, I will definitely try to replace them with something similar. I don't plan to go Apple Silicon. I don't plan to use any Apple development tools unless I need them. Some teammates use XCode for software development (they develop for iOS) so I have some new machines with just XCode, no 3PS, no mail, no nothing there. If those machines die, we can always buy a new one, install XCode and get going again without having to worry about anything else.

Thank you very much for this site and for your software tools. I use IntegrityChecker every day and it's an invaluable tool to keep trust in my backups.

MPG: pretty much on the nose. Developer machines can sometimes get by with older/slower Macs, but 16GB can get really tight. It all depends on what the tasks are. So you might have to upgrade and take the hits.

As for macOS versioning I agree: once a workflow is established, stick with it and never again do a major OS upgrade. Keep it as a “toaster” as long as it runs. That’s the only way professionals should operate: new OS only with a new machine. Exceptions abound, but don’t break that rule without strong reasons.


Good advice, but repair costs are scary expensive if it gets into a display or logic board. And laptops have a fairly high failure rate. So I strongly advise AppleCare for all but the cheapest laptops. And definitely for any machine $2500 on up.

It’s a question of risk assessment vs cost: as the cost of the Mac hit $2000 on up, AppleCare is an increasingly good deal for the risks, because the cost of AppleCare relative to the price of the Mac keeps decreasing. For lower end machines it’s a rip-off, as it forms a too-high percentage of the cost, but by the time you get to $2500, it’s down to 15% and keeps dropping from there.

Shame on Apple for charging premium prices with a pathetic 1-year standard warranty. Pro gear should carry a 3-5 year warranty, as it does with the better brands (OWC, NEC, and some others).

Fast and cost effective way to backup!

macOS Big Sur: how to List Active Kernel Extensions

Sometimes when diagnosing problems it is best to see what’s under the hood in terms of kernel extensions.

Kernel extensions should be strictly minimized to only those actually needed. Avoid software that requires a kernel extension without a very strong reason.

Listing active kernel extensions3

Open a Terminal window (/Applications/Utilities), and enter:

kextstat -l

The list from the command above will contain all Apple extensions, and usually the concern is only the non-Apple ones. The following will remove all the Apple kernel extensions from the list:

kextstat -l | grep -v com.apple

macOS Big Sur 11.3 Reader Comment: Multiple Issues including Kernel Panics

Reader Joe M writes:

I thought I had waited long enough so it was safe, also it appeared some of the recent security updates were delivered first to Big Sur.

I upgraded my iMac Pro video editing workstation from macOS Catalina to Big Sur 11.3.1. Here are some issues I've already encountered:

- CMD+F in Finder periodically doesn't put focus in search field. Workaround: resize Finder window, try again, eventually it will start working. Or just give up and manually click on the search field.

- Finder sidebar does not show SD cards if SD card is "Untitled". Workaround: just use desktop icon, or rename SD card in Finder, eject then re-insert.

- Kernel panic upon shutdown if multiple OWC Thunderbolt drives are connected (with or without SoftRAID). This isn't new to Big Sur but also happened on Catalina. Apparently MacOS is issuing synchronous (not asynchronous) dismounts. Depending on response time of various RAID arrays, the cumulative response time exceeds some MacOS shutdown timeout and it panics. If MacOS issued async dismounts it might not happen.

On Catalina, SoftRAID 6.x did a workaround to dismount all drives during shutdown, but this apparently quit working on Big Sur. They reported it to Apple back in Catalina; still not fixed on Big Sur 11.3.1. Example of kernel panic attached.

- On Catalina and continuing to Big Sur I had a problem whereby attempting to enter recovery mode with CMD+R would enter a boot loop, culminating in a kernel panic. Re-installing Big Sur didn't fix it, removing all kexts didn't fix it. Finally I erased the machine and reloaded my files using migration assistant from a Time Machine backup, that fixed it.

Several of my co-workers have Apple Silicon machines which must run Big Sur and they reported no major problems. However those are not running 3rd-party kexts.

However Big Sur has a kext detection feature and under some conditions it disables them all and you must individually enable each one in Security & Privacy. I previously tried leaving them all disabled and it still had the boot loop problem on CMD+R boot. OWC tech support said there was a Big Sur bug so even when disabled some 3rd-party kexts may still load.

Currently the only kext that shows as loaded is SoftRAID when I do: "kextstat | grep -v com.apple".

MPG: there are many more problems, but maybe macOS Big Sur is not worse than macOS Catalina. For example, I use Image Capture.app a fair amount, and it has 7 new bugs. Tip of the iceberg.

The real workflow destroyers are what concern me most:

  • Kernel panics every day or two using Photoshop. This has been going on for months. Adobe is working with Apple; I’m told these are Apple bugs. I have supplied complete system info and kernel panic logs to Adobe which has passed them onto Apple. No fix yet, no workaround. When it happens I lose a minimum of 10 minutes and up to 30 minutes due to flaky display syncing problems after reboot (voodoo to make it work)—which is itself another bug.
  • As of the latest macOS update, Photoshop now runs at half the speed of my iMac 5K when scripted. Apparently this is an issue with my 28-core Mac Pro and does not affect lower core-count machines.
  • As of the latest macOS update,  have a 2-3 second delay after opening an image. Again, seems to be peculiar to the 28-core Mac Pro.

macOS Big Sur 11.3: Upgrade ASAP for fix to 0-Day Gatekeeper Security Exploit (Apple CVE-2021-30657)

If you are running macOS Big Sur, update to 11.3 ASAP to get an urgent security fix.

In essence, you could do little more than double-click to open a document faking-it as an app, and compromise your entire machine.


It’s hard to operate in today’s internet environment without risk. But when Apple has bugs like this one, hardly anyone is safe, not even highly-knowledgeable people (including me). Break these rules at your own risk, since this latest Apple bug is an existence proof of that nothing is safe.

  • Unless you are CERTAIN that a file comes from a trusted party, do not download or open files received in email. Even then there is a risk since a friend or acquaintance could have been tricked, or infected.
  • Prefer plain-text emails.
  • Do not open attachments from unknown parties, particularly those forwarded by others.
  • Do not click on links in emails. Yeah it’s convenient—don’t.
  • Disable auto-loading of images in Apple Mail (Preferences => Viewing => Load Remote content in messages = unchecked/off).
  • Communicate by phone (voice) with persons sending you attachments/links to verify validity. And only those you already know.

Years of risk from sloppy practices at Apple?

Apple’s zealous security lockdowns have resulted in numerous impacts on those who use their computers for real work. Bars on the windows, rear doors locked, concrete bunker inside—but here we have the front door left wide open.

It took nearly TWO YEARS to find and fix this outrageous bug. Which is one more reason why waiting at least 6 months for a major macOS update is the smart move. But even that wouldn’t have worked in this case.

Ever wonder why Apple’s operating system releases require numerous updates in just 6 months? Check your premises on quality control—Apple ships by schedule, not by software quality.

About the bug

See also: Apple Security Bounty

 CVE-2021-30657 was discovered and reported to Apple by security engineer Cedric Owens on March 25, 2021.

An unsigned, unnotarized, script-based proof of concept application [...] could trivially and reliably sidestep all of macOS's relevant security mechanisms (File Quarantine, Gatekeeper, and Notarization Requirements), even on a fully patched M1 macOS system," security researcher Patrick Wardle explained in a write-up. "Armed with such a capability macOS malware authors could (and are) returning to their proven methods of targeting and infecting macOS users.

Ironic that macOS Catalina introduced the bug, what with all its extra security hassles. Of course, Catalina was a dismal failure in terms of so many other security bugs.

AnandTech: Actively exploited Mac 0-day neutered core OS security defenses

When Apple released the latest version, 11.3, for macOS on Monday, it didn't just introduce support for new features and optimizations. More importantly, the company fixed a zero-day vulnerability that hackers were actively exploiting to install malware without triggering core Mac security mechanisms, some that were in place for more than a decade.

..the flaw appears to have existed since the introduction of macOS 10.15 in June 2019, which is when notarization was introduced.

MPG: if the bug was being “actively exploited”, how can Apple be so out-of-the-loop to not know that after nearly two years? Why isn’t there a team at Apple that infiltrates the hacker community and/or actively buys exploits, so as to fix them?

Why doesn’t Apple owe compensation to the victims of this bug? A constant barrage of buggy macOS releases has a long track record of sloppy work—Apple should be liable given that track record.

iOS 14.5 and macOS: Removing/Breaking Useful Functionality One Small Piece at a Times

I often (daily) listen to a web podcast of sorts. Not a formal podcast as such*, just playing audio on a web page.

In all previous iOS versions, I could start listening, then switch to another web page. I like letting the podcast play while I read the news so I can use my time efficiently.

But in iOS 14.5, as soon as I switch to another web page, the audio is instantly cut off.

Is this just one more arbitrary design change by intention? Sloppy work? A bug?

No matter the cause, it has a major impact on the #1 time use of my phone. It’s so frustrating and disappointing that Apple keep destroying useful features on macOS, and now iOS.

* Apple’s formal podcast support sucks: downloading stuff I might not listen to, notifications irritating me, etc.

MacOS Big Sur 11.3 Update: woe to professionals daring to use dual displays on a Mac

Woe to professionals like me daring to use dual displays on a Mac.

The macOS BigSur update is itself bad enough in taking a very long time, many minutes of which are blank (black) screens. And when it’s done, it doesn’t beep or notify, it’s just an interminable black screen. I only figured out when it was done by checking every few minutes—it had booted up and gone into sleep mode.

That dog-poop user experience aside, the real nightmare is the 45 minutes I spent trying to get my dual display setup working again, a witchraft and voodoo affair involving:

  • 4 reboots
  • black main screen and black 2nd screen
  • black 2nd screen and lit-up main screen
  • lit-up main screen and black 2nd screen
  • flashing out of sync flickering problems.
  • warnings of outrageous syncing settings by the display—looks like a video card that can't do things right.

Do things work better if all displays are Thunderbolt? Not realistic for professional use.

By comparison, my 2nd display on my iMac running macOS Mojave works flawlessly for 10 years (various Macs). And it and its predecessors works flawlessly for a decade or more in total.

But the 2019 Mac Pro and either macOS Big Sur or macOS Catalina have been a daily headache because the problems above are a daily one, albeit usually only taking a minute or less to resolve.

I have no way to separate whether the issues are pure software or hardware only, or both. I just know that the same display works flawlessly on my 2019 iMac 5K with macOS Mojave.

I have a mac pro 7.1 with a Vega two card. I am using OS 10.15.7. I have two Eizo 2740 displays both running at scaled 2560 x 1440. They work perfectly—lighting up after sleep and reboot -- all open windows returning to the correct places. My experience is that the connection type seems to make a difference. My main monitor is connected to the video card Thunderbolt and the display port on the monitor. The second display is connected using Thunderbolt connection on the top board (one that USBC and Thunderbolt connections) and Thunderbolt on the monitor. [diglloyd: it's USB-C on the display, not Thunderbolt]

Some time ago, I tried using a Thunderbolt hub and had all sorts of disasters, similar to what you are describing. You might try connecting your monitors to the computer differently. In my case, that was the trick. Hope a different set of connections solves your problem.

MPG: the Eizo 2740 display supports USB-C and USB power delivery. It is also a 4K display. As such, it is not comparable to an NEC PA302W, which is about 5-year-old tech (but still the best panel available IMO).

The ColorEdge CS2740 features USB Type-C connectivity with 60W of power delivery. With a single USB Type-C cable, you can display video, transmit USB signals, and supply power to a connected device such as a smartphone or notebook PC. Simply plug in and get creative without worrying about additional cable clutter.

Basically, we are comparing apples and oranges here vs the NEC PA302W, which supports a wide variety of inputs (except Thunderbolt/USB-C) and a very wide range of input resolutions and sync rates.

Even if I had the funds for expensive new displays (I don’t), thing is, no panel on the market today has as neutral a backlight as the NEC PA302W with its truly neutral GB-R LED backlighting*. And nothing that ppi at 2560 X 1600 resolution. I don’t want inferior color and higher ppi and inferior “looks like” resolution (eg 1920 X 1080) on the Eizo 2740.

Some time ago I discusssed those USB-C to DisplayPort cables—total fail when I tried it. I’ve tried all viable options for the PA302W, meaning dual DisplayPort adapter, Thunderbolt Dock, USB-C to DisplayPort. The first two work with voodooo, the USB-C to DisplayPort cable fails outright. HDMI is not viable for optimal calibration. There are no other options.

It is also possible that NEC displays are troubled by newer Macs, and that other brands are not. But without comparing comparable technology, that’s a dubious premise. But the most damning evidence is that this all started around November 2019, prior to which operation had always been flawless.

* All other displays I’ve tried have a slight magenta tint which measures neutral, but is definitely not neutral as any side-by-side proves including other NEC displays. I have exceptional color discrimination, so most people cannot see the tint I can see. However, I have not seen the latest crop of displays and I don't know how the Eizo 2740 behaves. It uses some kind of “Wide-Gamut LED” and maybe that addresses the neutrality issue.

Automatic Image Downsizing in Apple Mail Wrecks Image Readability

As an ongoing headache, I regularly get emails from people with severely downsampled images so small that no text or details are readable. Screen shots, spreadsheets, etc. Which wastes everyone’s time.

The culprit is Apple Mail defaulting to a low-res size, typically “Small”.

Fortunately the fix is simple: make sure Image Size = Actual Size.

Of course if you really do want a downsized image, you can use the feature. But sending friends and family postage-stamp quality images is a bummer.
