Macbook pro 16 2019 freezes randomly and restarts

Replying to my previous post (my mac reboots as soon as I reach the Catalina login screen).

I installed Windows 10 via bootcamp. No problems starting. No crashes when sleeping (closing the lid and re-opening).

All my thunderbolt3 ports work (at least as USB-c ports, I don't own any thunderbolt3 accessories).

I'm pretty sure this is a software issue. Rumor is it may be fixed in 10.15.5 https://mrmacintosh.com/10-15-4-update-wake-from-sleep-kernel-panic-in-16-mbpro-2019/

How do you spell "Class Action"? 2019 16" MacBook Pro. So very disappointed to see so very many people impacted, especially during this time when we so need our computers. Apple should really make this right for anyone who bought one.

Hi, this morning 21/05/20 i got the latest beta, and fingers crossed its fixed my issue the reboot powerplay.

i have done 10 restarted and several power up and power downs, with no issues.

Will see how the week progresses.

I also had confirmation that apple are aware, and it should be fixed.

looks like the latest beta build which installed this morning has resolved it for me.

its still obviously very early, so ill update this thread next week ether way.

so looks like not hardware as some people have mentioned.

many thanks

Mark

Update here, just upgraded to 10.15.5 Beta (19F94a) - panic PowerPlay Failed Resume IS NOT SOLVED. My plan is to wait for the final 10.15.5 release and go for a refund in case it'll still be there.

p.s. Shame on Apple. I've been using Macs (iMac, Mini, Air) for the 10 year and this is the first time I've switched to PRO model just to find out that it is an overpriced, untested piece of ... hardware.

Hi yes your correct :( it seems ok all day yesterday but this morning its back to normal with reboot loops.

i am going to do the same as you and wait for final release.

Then pursue apple for a replacement or refund.

I get my fixed Mac 16 yesterday, so far it works well for more than 12 hours, no more abnormal shutdown when awaking from sleep.

So my suggestion is if you are experiencing the same error:

1) GPU Panic .... PowerPlay Failed Resum

2) kernel: (AppleSMC) Previous shutdown cause: -20

don't waste your time to call Apple Support, they will tell you do a lots of test, such as Reset SMC, PRVM, reinstall, bilabial... It's no use at all. Just to Apple Genius Bar and they will change you the Logic Board. Then this problem has high possibility to be fixed.

I still can't 100% confirm the change of Logic Board will fix the problem. Because someone report replacing Logic Board didn't fix this problem. But it seems like it fixed my laptop. And when I get back my laptop, the MacOS version is 10.15.1 ! I don't want to upgrade to the latest 10.15.4 now, so I disabled the Auto Upgrade function immediately when I first login into the system. Because both the system version down to 10.15.1 and Logic Board was replaced, I am not sure which one resolved the problem.

I will continue to watch.

Glad to know yours was fixed as well. Mine is working fine for more than 30 hours.

What's your current MacOS version? This may help to diagnose the issue whether it is caused by software or hardware.

Yes, same here. 10.15.5 beta has finally pushed it over the edge for me. Worse than ever.

If Apple doesn’t resolve this, I am never buying another laptop from them - after 35 years of doing so. This has been ongoing for months now and way too many of us are impacted.

What is surprising is now useless Apple Care has been in this context. The rote script some of them follow after being clearly told what has already been tried is sadly reminiscent of a bad workplace movie. Even if you can get escalated to Executive Relations, as I have, they just defers to Apple Care and the cycle begins all over again.

Make sure you submit your data after a problem via the Feedback App, as that is what they look at.

I've been with Apple since the original 1984 Macintosh, and I still have it. Never have I been so disappointed of an Apple purchase. Normally when I spend $3K, $4K, I don't care cause I know the quality product I'm getting. But this garbage and LACK of assistance for something SO expensive- yeah cuz you don't see Apple folks coming in here trying to help, we're like on our own!! I got this Macbook Pro 16 (2.4 GHz 8-Core Intel Core i9, 64 GB 2667 MHz DDR4, MD Radeon Pro 5500M 8 GB, 8TB SSD) to replace my previous 2015 iMac for mobility convenience. Not only it cost me slightly double (almost a car) but it runs slower and has all these hardware issues. Plus some stupid mouse lag that slows everything, even youtube video playback lag... WTH!??!?!? -

I am SO mad with Apple. I had a High Sierra partition on my iMac to run legacy 32bit software I need which replacing would cost me thousands. Now I can't even load that partition onto this stupid thing - it just doesn't let me. I've gone down dozens of rabbit holes just to come out frustrated in search of another one. We complain here but only ones I see giving "options" are the guys looking to bring up their level. Just finding something in this discussion board is difficult!

Yes, there are many defective laptops, but much more stable and correct. Apple has a fairly adequate policy, if 3 repairs do not fix the problem, you will be offered a replacement for a new one or a refund. Yes, unpleasant, it will take some time. But in the end you get your working device.

I think I found the culprit for my random freezing. I used to experience random freezing at least once a day, even when im not doing anything. System is idle. In all of that instances, Viber is open and seems the first one to freeze.

Ever since uninstalled Viber, my machine has been super stable for 2 weeks now. No random freeze anymore.

Im not sure why this has fixed my issue, but this just goes to show that, at least for me, this is not hardware issue.

Random freezing occurs without any third-party software. Because they are random, which can happen often, then they may not happen for several days. Prior to returning my device, I noticed that it could freeze when checking the hash of the huge file (but not every time).

But my stable laptop works properly under any load with any software.

mhil, have you upgraded to 10.15.5 beta 5?

@ksk6794

Im still on 10.15.3.

Maybe im just lucky im not sure. But 2 weeks without any random freezing is really amazing for me.

my machine:

16 Inch i9 2.3

32GB Ram

1GB Rom

4GB Video

MacOS: 10.15.3

Use case:

Parallels and VMware VM (Heavy)

GNS3

some Finalcut

and other light use cases.

Ah, another important detail, this can only happen when working with Intel HD Graphics.

Those who work with graphics software may not notice this defect, because graphic and video editors (as well as games) automatically switch to AMD.
