2016 MacBook Pro: Cannot Sustain Performance Under Load

Mac wish list •  all 2016 MacBook pro models at B&H Photo • all 15" Apple MacBook Pro 2016 models •  all 13" Apple MacBook Pro 2016 models. MPG gets credit if you buy through those links.

While testing the 2016 MacBook Pro, a consistent pattern of declining performance was observed. For example, with 10 iterations of of the Photoshop sharpening test, the 2016 MacBook Pro declined in performance by 23%. No such decline was seen on the iMac 5K or 2013 Mac Pro.

This differential helps explain why the 2016 MacBook Pro is slower than the 2013 MacBook Pro on the Lightroom import test*.

2016 MacBook Pro: Cannot Sustain Performance

This finding may be of keen interest to anyone processing video or importing into Lightroom or any task that incurs a sustained load.

* Which is not a statement about performance in any other area, particularly GPU-intensive tasks or video processing. Performance is always task specific, not some hard rule. I expect the 2016 MacBook Pro to outperform earlier models for some tasks, including GPU-intensive taskes.

This is a sad sad day of recognition for me. I really wanted to keep on loving Apple, have their phones (7 and 7+) laptops (2011 15” MacBook Pro and a 13” 2015 MacBook Pro), 2013 Mac Pro, their Airport Express (use it with my DAC and HiFi) and Airport Extreme router, and 24” Cinema display plus several iPods. Most of all I used to really loved their software. All since 2003 when I first starting buying their equipment and stock I looked forward to their next innovation and improvement eagerly. Not anymore. Seems like everything need several updates to repair problems newly created.

Now, no more display or router, high priced crappy performance for new machines, everything is soldered and or requires a series of connectors and a dock to use all for the sake of small and light. What happened to useful and reliable??? They may have had a vision of where we should be going (at least with Jobs), but I think their vision has turned to greed and is verymuch shortsighted (cannot see the tree before the forest with each amputation of their product lines).

My 2013 machines may be the last Mac products I ever buy at least for quite a while. Hopefully they will last 10 years (I have a 2006 iMac that still works well; gave it to my daughter with an upgraded SSD). Most of the software I use for my visual and musical entertainment and work should be good enough for my needs for the next 5 years maybe more. Even the iPhone will soon be no different than the rest.

Eventually the only thing they will be selling is the phone at over $1,000 (my current 7+ cost over $800 with the 128GB up from $600+ for the iPhone 6+) and service subscriptions for things that used to be free (TV and music); don’t forget the fee for storing your stuff in the Cloud. Microsoft and Adobe are not too far behind and getting all of us hook on a perpetual fee service.

Perhaps that is where the world is going, everything is rented or leased with a few owning all the capital assets.

Hopefully no Soylent Green in my lifetime, please…

What software/process do you use to wipe all personal data off a Mac that is being returned, if any?

MPG: if booting off another drive and completely destroying everything on the drive is the goal, Disk Utility can do that.

Most of the time, I use my own software (DiglloydTools), specifically the wipeFree command (twice for SSDs assuming 80% or more of the SSD is free) and wipe command in diglloydTools 'dgl'.

See my Nov 22 post 2016 MacBook Pro: Return It and Stick With 2013 Model? for my reasoning.

I’ve made my decision. The 2016 MacBook Pro is very nice for anyone who does not own a reasonably recent MacBook Pro Retina, but for me (Lloyd) the value proposition is just not there—it is a travel machine only (6 weeks or so a year), and it’s no faster than my 2013 MacBook Pro for what I do. The value proposition is just not there. I’d rather wait a year for a model that has more features, or at least 32GB of memory and/or a faster CPU and GPU.

This is the first and only Mac I’ve purchased with the intent to keep and use and then returned. Which speaks volumes about Apple’s priorities in hardware development. The 2016 MacBook Pro is an excellent machine, superior to the 2013/2014/2015 models in most all way, and were I buying a laptop for the first time or replacing a far older one, I would be delighted. But it just does not offer meaningful value for me vs the 2013 MacBook Pro I already own.

I’ll finish up various tests before it goes away in the FedEx truck on Monday.

Richard H writes:

Especially since the 2016 MBP does not allow RAM or HD upgrade. They are becoming more like iPhones, where a user needs a new model every 1-2 years. I'm sure the Apple business lease program and Apple iPhone Upgrade Program will filter down to non-business MBP lease consumers in 1-2 years.

MPG: seems like a good possibility.

Frank K writes:

Just to let you know that I've returned my full blown MacBookPro 15" 2016 as well. Got random but frequent issues with the track pad (right click commands even when touched the trackpad in the middle or upper left corner, no palm contact involved BTW.)

And graphics issues while using Capture One Pro 10. Every adjustment with the arrow keys result in a short greenish noise pattern on the left quarter of the screen.

Battery live with an external 27" NEC display and Capture One / PS use is down to 4 hours.

My 2011 17" MBP will have to do the job until the next iteration of the current models in fall 2017. Yes, screen is great, graphics performance is more snappy, the fan hardly kicks in but it's just not a big enough upgrade for me - even with a 5 year old model. I do my critical editing work on an external monitor anyway and have upgraded the internal HDDs to SSDs in the last 2 years so as long as the thermal meltdown isn't on the horizon I'll have to stick with what I have.

MPG: I have no hesitation in recommending the 2016 MacBook Pro for a new buyer, assuming it is free of graphics glitches.

Photoshop + Lightroom for a Year for $88

I see $10 a month for Photoshop and Lightroom as a bargain for any professional.

Today only, Photoshop and Lightroom CC 12 month subscription is only $88.95, which is $7.41 a month. Compared to my cell phone bill, it is less than the tax.

Deal ends at midnight tonight, EST.

...

It neatly solves another nuisance for me: one purchase, vs the monthly $9.99 charge, each of which I have to enter in my accounting program to balance the books. As I have two subscriptions, that’s 24 annoying entries per year. I called Adobe and they refused to allow billing on a year basis.

So now I can pay once, save $31 X 2 = $62 and make only two accounting entries. per year.

Update: gah! There is a limitof one (1) purchase only (I tried!):

Please note: You have exceeded the limit for ADCCPP12MS-Creative Cloud Photography Plan (12 Month Subscription, Download). You currently cannot purchase additional quantity. The item has been removed from you cart

Here’s how it works:

Apple Mail Calendar Spam

There is a new type of spam making the rounds: spam email containing calendar appointments, which Apple’s software picks up on to annoy me every day.

In effect, Apple provides a spammer’s wet dream toolkit. A spammer counts on some very low response rate, but if spam is never seen it fails the spammer’s goal.

So Apple does the job for the spammer by forcing you to see it: not only is there an in-your-face notification, but it also has to be clicked to gotten rid of—and clicking the wrong button (fairly easy to do) puts spam into Calendar!

Of course if your preferences include auto-adding Calendar appointments from mail, then you've got a serious accumulating mess on your hands—see possible workaround below.

Spam email with calendar appointment, disruption courtesy of Apple
Apple Mail Preferences => General

This macOS behavior above is particularly irksome because I have my mail configured with Add invitations to Calendar = Never. So why is Apple forcing me to respond to junk mail spam to go into my Calendar?

There is also a risk that a mail message with a payload of calendar appointment could be a vector for a virus or trojan if a weakness is found in Mail or Calendar code. Auto-this and auto-that can be very bad for security. If such a weakness is found, tens of millions of users could be compromised in a few hours.

I’ve changed my settings to New message notifications = VIPs, but since the VIP feature has been non-functional for 2 OS releases, in effect I cannot get any notifications at all.

MPG hopes that Apple will issue an OS update that properly respects user preferences.

Unchecking Show invitation messages in Notification Center in Calendar might help (not sure until some time passes):

Apple Calendar app settings => Alerts

Evan A writes about iCloud calendar settings:

Thanks for all your insights over the years, they are extremely helpful in my day-to-day Mac use.

I too have been suffering from the calendar spam issue for the past week, and according to MacWorld today the only way to shut it down is via iCloud calendar online (just another reason to love iCloud).

MPG: Evan A refers to How to disable calendar invite spam on your iPhone, iPad, and Mac. I have not tested or confirmed this solution as I avoid the bug ridden iCloud offerings entirely.

It is not clear that iCloud online is the only solution (or if it works) and since I never use iCloud on the web, it was distasteful to have to go there. Still, I did so and here is the suggested setting:

2016 MacBook Pro TESTED: 10-Bit Color With External Display

Mac wish list •  all 2016 MacBook pro models at B&H Photo • all 15" Apple MacBook Pro 2016 models •  all 13" Apple MacBook Pro 2016 models. MPG gets credit if you buy through those links.

2016 MacBook Pro: 10-Bit Color With External Display

See my reviews of NEC wide gamut displays and other displays.

The built-in MacBook Pro display supports only 8-bit color**.

Attaching the NEC PA244UHD 4K display to the 2016 MacBook Pro confirms that the MacBook Pro drives the display at 60 Hz and 10-bit color*.

Portrait orientation (tall mode) works properly also, as do all the scaled resolution settings, although the default “Best for Display” is the wrong choice (too enlarged).

  • The OWC Thunderbolt 2 Dock worked flawlessly with the display being detected immediately. It is on sale now for about $200.
  • The Apple Thunderbolt 3 to Thunderbolt adapter did NOT work to drive the display. Unplugging and replugging and rebooting several times failed to ever detect the display. This is odd, because the same adapter was used to connect the OWC Thunderbolt 2 Dock.

So here we see one more hassle with the 2016 MacBook Pro: the Apple adapter does not function! However, since the OWC Thunderbolt 2 Dock (and future OWC Thunderbolt 3 Dock) offers many ports of several kinds, the smart move is to get both and use the Thunderbolt/MiniDisplayPort port on the Dock for the display, and the Apple adapter for any kind of external device other than a display.

* “30-Bit Color” means the 3 RGB channels at 10 bits each.
** “32-Bit Color” means 3 RGB channels plus alpha channel at 8 bits each.

2016 MacBook Pro: Strange Rainbow Beachball Behaviors

Never observed with the 2013 MacBook Pro, and both wired with gigabit ethernet—

The 2016 MacBook Pro regularly does a rainbow beachball for a second or two, then all is well. It seems to happen if the machine has been idle for a bit, but not gone to sleep. In three years I (Lloyd) have not observed anything like this behavior with the 2013 MacBook Pro.

The cause is unclear: could it be related to some kind of new power management algorithms? It’s minor but annoying, along with the chimeless black screen guessing game at system boot. These two behaviors constitute annoyance only, but they are surprisingly irritating compared to the rock solid predictable behavior of the 2013 MacBook Pro.

I am thinking about buying the Mid 2015 15inch MBP, 1TB, 16gb. I’ll get the ports, display and not give away too much performance. Am I missing something or does this seem like a reasonable move for my photography?

MPG: if one already has a 2013 or 2014 MacBook Pro, then the 2016 model runs the gamut from compelling to a headache; it all depends on how one uses it: desktop or travel, type of work done with it, size of jobs (e.g., memory limits), etc. Even something as simple as external power could be a compelling feature for some users.

The internal SSD of the 2013/2014/2015 MacBook Pro SSD can be upgraded to 1TB.

In general, the MPG recommendation is that anyone with a 2013/2014/2015 MacBook Pro should skip the 2016 offering unless there is some compelling feature (such as external battery power). For example, that a video crew or pro photographer shooting offsite (or even onsite) would find external battery power via USB-C a compelling feature both for runtime and for avoiding trip-over risk of wall cords.

The other reason to upgrade is that the expense matters not, but that is not my situation. The top-end model whose price with AppleCare and tax approaches $5K would be much more palatable, for, say $3200 (Apple has not added any value with the 2016 model in terms of core specs vs price). I’d still be slightly grumpy about the performance sidegrade, but accept the price and make use of the new features like the external battery power—I travel a lot in the mountains and runtime is a hassle on the 2013 model.

TESTED: OWC 40TB Thunderbay 4 Mini SSD with RAID-0 Stripe and RAID-4 Fault Tolerance

GetOWC Thunderbay 4 Mini SSD RAID Edition at MacSales.com.

Following up on yesterday’s overview of OWC 40TB Thunderbay 4 Mini SSD, below are performance results with both RAID-0 striping and RAID-5 fault tolerance.

RAID-0 striping

This is the best performance MPG has ever seen with Thunderbolt 2 (or from any external SSD). It sets the new benchmark.

  • Read performance flatlines at 1425 MB/sec
  • Write performance flatlines at 1192 MB/sec
 
30TB RAID-5 SSD: OWC Thunderbay 4 Mini

Those are average figures across across a gigantic 39.37TB volume! Context: those figures beat the internal 1TB SSD in the MPG 2013 Mac Pro. It looks like Thunderbolt 2 has throttled the read performance. MPG expects OWC to offer a similar solution with Thunderbolt 3 in 2017, in which case the read speeds should rise to even higher levels.

RAID-4 (fault tolerance)

This is the best performance MPG has ever seen with Thunderbolt 2 (or from any external SSD). It sets the new benchmark.

  • RAID-4 Read performance flatlines at 1224 MB/sec
  • RAID-4 Write performance flatlines at 853 MB/sec

The RAID-4 performance is outstanding in two ways:

  • Flat line consistency across the entire 29.8TB volume.
  • Data rates within a few percent of the theoretical speed, that is, 75% of the speed of RAID-0.

It’s a superlative performance from four SSDs in the Thunderbay 4 Mini witih SoftRAID.

Tested using disktester fill-volume --xfer 128M with diglloydTools disktester

Graph shows writes read filling the volume to 99% capacity with 1000 test files.

40TB SSD: OWC Thunderbay 4 Mini

Following up on yesterday’s overview of OWC 40TB Thunderbay 4 Mini SSD, here is performance.

This is the best performance MPG has ever seen with Thunderbolt 2 (or from any external SSD). It sets the new benchmark.

  • Read performance flatlines at 1425 MB/sec
  • Write performance flatlines at 1192 MB/sec

Those are average figures across across a gigantic 39.37TB volume! Context: those figures beat the internal 1TB SSD in the MPG 2013 Mac Pro.

There looks to be cruising room here for 4K raw video capture. Or any hyper demanding task for writes and even better for reads.

It looks like Thunderbolt 2 has throttled the read performance. MPG expects OWC to offer a similar solution with Thunderbolt 3 in 2017, in which case the read speeds should rise to even higher levels.

Tested using disktester fill-volume --xfer 128M with diglloydTools disktester

Write @ 1137 MiB/sec = 1192 MB/sec, Read @ 1359 MiB/sec = 1425 MB/sec
