16" MBP GPU Panics

[iMi]

Just wanted to chime in to say that the MBP16 has been the least reliable machine I've owned to date, except for a MacBook I owned a decade ago, which was a lemon and Apple replaced. I get wake from sleep crashes, beach balling and issues related to external display. It seems to be all software related, but not sure. Something is off about this unit.

 

[PBG4 Dude]

All,

I too am experiencing kernel panics on my MPB 16", 5500M on 10.15.5 when waking from sleep.

One further layer of annoyance is my touchbar has stopped working altogether. It is blank and does not respond to touch at all.

Resetted SMC, VRAM, safe mode and reformatting does not help.

Obviously very annoying. Should I wait for this fabled software update or shall I take the machine back to the Apple Store...?

If your touchbar isn’t working you should definitely bring it back to the store. If it isn’t coming back after a reboot, something bad has probably happened.

 

[simonmet]

For the record, my Mac hasn't panicked in about two months. Whatever it was seems to have resolved, thankfully. It's very reliable now.

 

[iMi]

I have a theory (or maybe wishful thinking).

The MBP16 is a brand new machine, right? Could it be that Apple is still working out software issues related to the new hardware?

I mean, I have problems with Apple's own stuff, including products made for Apple -- such as the 5K UltraFine. I have issues with third party products, like the keyboard and mouse becoming unresponsive, as if bluetooth just cuts out momentarily (MX Keys and MX Master 3). Last night I ordered Apple's keyboard and trackpad to see if that makes a difference. Another problem is that if the machine is in clamshell mode and I restart the computer, for whatever reason, the keyboard and mouse will not connect. I have to open the Mac and use the internal keyboard to log in. Doesn't make sense.

In addition, I have random screen hue/color changes. It flickers between a warmer and cooler display as if the TrueTone was malfunctioning. Outlook beachballs every time I write an email. Same happens with Apple's Mail, but less frequently. Weirdly the fans don't kick in particularly hard when I stress the machine. It just seems like software/hardware synergy that made me such a long-term fan of Apple seems to be disintegrating.

I've been bugging Apple support for over a month and upping the pressure each time. It's now gotten so bad that each time I boot the machine, it crashes first, reboots, then succeeds. It crashes when starting a Skype for Business call. It crashes when sleeping and when shutting down (so no reliable way to turn off the machine)...

So when I explained the impact in great detail to my most recent contact at Apple support, he asked me for some time to consider it. When he came back to me, he had arranged a swap for a brand new, identical machine. Which is a pretty strong effort from his side, because internally the issue is marked as software and "tell the customer to wait for a software fix".

Not holding my breath, but hoping that this new machine will be more stable...

interesting. I have the same issues and also spent an hour on with apple support this morning (case has been open for 10 days) and they are insistent that machine replacement is not an option unless it can be proven to be a hardware issue. The on board hardware diagnostics on my machine gives no errors so the only option offered to me was to take it to a Genius Bar.
Good luck with your new machine. I hope it fixes it for you. I know well how frustrating this is!!!

[UPDATE] I took in my MBP 16" to a local Apple Store. They ran a few diagnostic tests, wiped my HDD to see if it would still reset and throw up a kernel panic, and it did. So they shipped it to their service center in Houston, TX.

Got it back a few days ago (pretty fast turnaround) and it's no longer randomly resetting. Looking at the work order they included with my MBP, they replaced the logic board (processor, memory, graphic) and touch ID board. It looks like they replaced the GPU with the same one unless they're using an updated version of it.

I had mine sent in and they had replaced my logic board and touch ID - did not fix the issue.

 

[idch]

My MBP 16" with Radeon 4GB auto-restarts every night if I leave it in sleep mode connected to external monitor in clamshell mode.

I don't know at what time it happens but I see windows login screen (bootcamp)

It's a pity since I replaced my old MBP 15" 2015 which worked in clamshell mode flawlessly.

I have this error:

panic(cpu 0 caller 0xffffff8015e9167c): Sleep transition timed out after 180 seconds while calling power state change callbacks.

and something about IOGraphics

I don't really think that I have the same problem with GPU which needs to be replaced, but who knows.

It does not freezes or something, daily usage is fine. But clamshell mode auto-restarts are basically from my day 1 of usage

 

[PeterJP]

So I got my new machine in on Friday. Interesting, actually, that they replaced my refurb by a brand new one. It's stable after a few days of use, but the previous one started crashing only after a month... Fingers firmly crossed and sleep/PowerNap firmly disabled...

In the meantime, any updates on 10.15.6 or BigSur? Or the 5600M machine?

I bought my 16” MBP in November last year. I’ve been using it with an LG 5K display since I received it, but I started having issues with it in June. It started with total hangs and garbage on both of the displays. I also had reboot cycles. The computer seemed to be fine when disconnected from the display, and I could boot into safe mode. I tried all the usual things, reset SMC, reset PRAM, boot into diagnostic mode (which reported no problems).

I opened a support case with Apple and ended up sending my computer to them. After a week, they sent it back wiped with a fresh OS install stating they could not reproduce the problem.

The computer worked fine for a couple weeks until one day, the system hung and rebooted. I wiped the disk this morning and did a reinstall from the internet. On the first reboot after the reinstall, it panics and reboots. The only way to get it out of that cycle is to boot into safe mode. Only then can I complete the setup process. And this is without an external monitor attached. With 10.15.6.

I guess I’ll try opening another support case with Apple. Maybe I can get lucky and find an Apple store that’s open with available Genius slots.

I had almost exactly the same scenario as in your last two paragraphs, assuming that when you boot into safe mode you get a "PowerPlay failed to Initialize" panic report (I updated my blog this morning with the gory details). Eventually I did manage to get Apple Support to take it for repair and they are currently replacing the logic board.....

My view (from speaking to Apple Support) is that if you have JUST the issue where you get a "PowerPlay failed resume" panic when waking from sleep, then 10.15.6 is supposed to fix that issue, although they have not included it in the release notes. If you get other issues (I also got "PowerPlay failed to initialize" at boot and "userspace watchdog timeout" at random during normal use) then in my case at least 10.15.6 made no difference, and (eventually) Apple have taken my machine for repair and are currently replacing the logic board.

Which issue did you have, and are you on 10.15.6?

 

[Kohji Matsubayashi]

Big Sur Beta 3 - no difference - strange display like always (since some version of Catalina). No crash, but strange/weird display here and there.

 

[nbuubu]

FWIW Big Sur Beta 3 has almost completely cured my MBP 16's kernel panics. I can successfully have it sleep connected to an external monitor in clamshell mode, which has been an instant-panic for months, and wake without a restart crash.

But, I say almost completely, because it just crashed with a x86 CPU CATERR detected panic, which I'd never seen before, with an external monitor attached and the laptop open.

Still, one crash in three days is an improvement.

Really regretting giving Apple another chance with a laptop.

Well, for what its worth I went through all of this in the last little while. I've had this 2019 i9 MBP 16 for nearly a month and a half with absolute no issues -- then poof! I ran into this issue (MBP boots 75% through login sequence, immediately reboots on its own, repeat ad naseum). Safe mode works just fine, log dumps indicate the power play messaging, etc.

I called AppleCare+ (thank god I always buy this service) and patiently spent nearly 2 hours on the line while they got me to run diagnostics, reset PRAM/SMC, re-install MacOS from scratch, etc. Finally got scheduled to drop off my MBP at the local Apple store 2 days later.

Prior to dropping it off, I read everything I could on this issue and tried whatever I could. Even did full restores from time machine and complete factory resets with no go.

Apple Store genius ran his diagnostics and was able to replicate everything. Long story short, it took them 4 days to do all the testing, replaced the logic board and Touch ID, and more testing to confirm problem went away. I know this would have been covered under normal 1 year warranty, but god help me if I was outside of warranty without AppleCare+. The bill was over $1100 CDN!!!

Anyhow, everything works again -- full restore from Time Machine and then upgraded to 10.15.6. No issues since. Hopefully that's the end of it. I don't know, maybe a bad batch of logic boards?

Only advice for everyone going through this, get it to an Apple store and have them deal with it. There's nothing an end user can do.

Thanks for all the helpful information in this thread, it helped my mindset that I wasn't alone with this weird sudden problem!

Fully concur. Very similar experience. My residual concern is that it was ok for a while then failed, which points to an endurance issue, hence may happen again over time... keeping my fingers crossed...

 

[Reflexiste]

I just received my new MBP 16" with the 5600m card and any iGPU panics issues to report at this time.
I admit that the fear of encountering these issues with the 5500m, I preferred to take the 5600M model.

 

[tolwyn21]

Yeah exactly my thoughts too. For the month and half since I moved from my 2016 MBP 15 to this new 2019 MBP 16, it has primarily been just MS Office work and probably 2-3h a day gaming in Bootcamp which I do know pushed the fans and graphics card. Supposedly the thermal/fan system is much better in this new MBP compared to my old one and I did the same stuff. If that gaming 'overtaxed' the graphics system and somehow caused the logic board failure, this is going to be ugly. Well, I'll just have to see what happens in the next month and half now.

After pushing support hard, they exchanged my machine for a new one. Which is interesting, because the original one was a refurb I asked if I could upgrade to a 5600, but support strongly advised me not to upgrade components if the purpose was to make a malfunctioning machine work better. So I have another 5500/8GB again. No crashes so far after almost two weeks. My new machine was built in July.

 

[Reflexiste]

Good news but at this time we are not sure since Apple does not communicate if there has been a change of motherboards at the factory.

 

[kaans]

9 days for me to decide whether or not to get AppleCare+ - I don't think it's worth the $380, better to sell the device for parts when it fails I speculate, but I might be wrong, it's hard to make a logical decision when hardware are so erratic lately (the conspiracy theorist inside me blames China to be honest, I think the assembly factories must be doing something intentionally wrong as a soft sabotage, may be the reason why Apple is gently trying to move manufacturing out of there)

Anyway, when I first got the device, I had one gpu crash while Chrome was full screen when I was waking the device up, Geekbench 5.1 test doesn't crash the device, so I hoped I was ok

Today got a "x86 CPU CATERR" when I connected my external screen, I connect/disconnect the device 2-3 times a day on average, first time it crashed

I got paranoid again but I'm hoping to squeeze a healthy 18 months out of this device, really hope the caterr won't repeat

My work MacBook Pro 16” with 5500M had been giving me GPU kernel panics randomly while using external monitors. Took it to Apple and they said they’d need to replace the logic board and I’d have to go without my computer for over a week! Luckily our IT department had a couple brand new MacBook 16” of the same mode in stock so they just swapped it out right away. This one seems to be better and haven’t had any kernel panics yet.

 

[Stv Pmr.]

Hello people,

I had the same kind of GPU panics on one of my 16" macbook pro (bought two, the more recent one did not have any of these GPU panics)

Had to bring the failing macbook to a Apple Store (genius bar), they changed the logic board for free (2 days in Paris), I asked questions, they don't really acknowledge this issue...

It has been 2 weeks and no GPU panics so far (macOS 10.15.1)

I havent had a single crash or issue with mine, whats your manufacturing date? I own 4 of them and i cant really complain about anything.

June, Late June, July, Mid July manufacturing dates.
