Looks like something is wrong with GPU (GPU Restarts)

Didn't solve anything... another restart today morning... I will try next to disable powernap - but this shouldn't be a solution, it's not expected to need to disable functions in order to get rid of errors...

I also have the same problem. When the Mac is asleep, and I open the lid, nothing happens. I have to restart, and then get this error. Called Apple support - reset NVRAM and SMC, the usual, and then they are looking to have me do an OS reinstall.

I have exact same issue too. My MBP 16 crashes every time I connect it to external monitor. Sometimes it restarts and give me message "... MBP was restarted because of problem..." or I'm not able to wake it up from sleeping mode.

I have the exact same problem with sleep. Mine just started with the "upgrade" to 10.15.4 though and wasn't an issue before. MBP 16" 16GB, 1TB, i9. Purchased December 2019. I did contact Official Apple Support. The only advice I received was to reinstall MacOS. I'll try the SMB trick first before I go to the last resort. Especially since this just started with 10.15.4, and I doubt reinstalling the same OS will have any effect.

Just to follow up, I removed the Universal Audio software and kexts from my system, but it had no impact on this bug.

So far, I’ve tried everything support has suggested (reboot to safe mode, reinstall macOS), but obviously this had no impact on the bug introduced in 10.15.4.

I also submitted sysdiagnose data 3 days ago, but can’t get my Sr. Advisor (or anybody at Apple) to follow up. They’ve missed 2 callbacks, and I wasted 1.5 hours on the phone trying to get an update. Every rep I’ve talked to (except the first one) has denied this is a known issue, and claimed I’m the first one they’ve talked to about this problem.

I really wish Apple would at least acknowledge this issue so others don’t have to waste so much time eliminating variables. That said, I think it’s still worth calling support to report the problem and ask them to escalate it so they know it’s impacting everybody (or most people). I’m on my 3rd 16” MBP i9 w/ 2TB SSD since December.

Best of luck to everybody...

I have the same kernel panics on pretty much the same configuration. Tried all kinds of resets, fresh install, .. nothing helped.

The latest thing I have tried so far prevented crashes: I turned off Power Nap in the energy settings. Can someone confirm whether they also see crashes without Power Nap? I would still expect Apple to fix that of course.. but at least if that reliably prevents the kernel panic, I could live with that workaround for a while.

Hi everyone, just an update on what I've done, as has so far worked for me. I'll post again if this doesn't work. lepidium post his fix above which is interesting in that I also found help in the Energy Saver Settings. However I do have Power Nap enabled, but I also have Prevent computer from sleeping automatically when display is off under the Power Adapter settings. I typically have my computer plugged in all the time. I have not done the SMB trick above or reinstalled MacOS.

Thinking back to around the upgrade, the setting I did change when things started to go south, was Automatic Graphic Switching. I had the box unchecked to force the use the graphics card. I have since reverted back to the default, Enabled Automatic Graphic Switching and the system has remained stable. Granted it's only been about 2 days, but I have yet to have the kernel panic occur again since changing the setting back to default. I'll report back if things change. Good luck.

Yes.. given that the panic only happens during/while entering sleep mode, deactivating it will definitely help as well. I didn't want to deactivate it completely, though. Now, with power nap off and no crash since, the next step obviously would be to figure out what exactly during power nap causes it (could be anything like checking mail, update photos or syncing iCloud). Then again, even if we did know, none of them can be turned off individually anyway.. so I might just as well keep power nap off in full.

Hi All,

I hope the automatic graphics switching and/or power nap settings help others, but I wanted to mention they didn’t impact the crashes on my particular system (16” MBP w/ 8GB 5500M GPU, 2TB, 32GB).

Disabling automatic graphics switching may have made the crashes slightly less frequent, but nothing dramatic. I’ve tried enabling power nap, but didn’t notice a difference on my system (so I keep it disabled).

FWIW, I usually leave my MBP plugged into power, and I *think* the crashes tend to happen about 1-4 hours after sleep. My MBP has occasionally spuriously woken up from sleep (my Apple Watch notifies me it has authenticated my MBP login, but the laptop screen doesn’t turn on). The last time this happened, I noticed the crash appeared in the system logs About an hour after the Apple Watch notification. My MBP is ~5 feet away from my bed, so I would have noticed the display turning on...

Anyway, hope this helps!

P.S. Apple support was supposed to call back with an update ~3-4 days ago, but as seems to be the norm these days, nobody calls back no matter how many voicemails I leave for my Sr. Advisor.

I tried now a few things. So its not the problem with peripherals. Tried every possible combination...

Now I found out it has to do with powernap when on the power adapter.

If powernap is off I have no issues.

I got a GPU Restart Failure:

Same problem here on a MacBook 16" 2,3 GHz Intel Core i9 | 16 GB | AMD Radeon Pro 5500M 4 GB

panic(cpu 2 caller 0xffffff800d416487): "AppleIntelFramebuffer::setPowerState(0xffffff81bc472000 : 0xffffff7f909a8d88, 1 -> 0) timed out after 45953 ms"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6153.101.6/iokit/Kernel/IOServicePM.cpp:5296

Happening everyday after night - think it started after the last OS X update...

I've got the same issue with my 16" device and solved it, at least temporarily. My MBP is the cheapest model available.

Interestingly there was a problem with the unlock via Apple Watch at the same time. It simply didn't work.

After processing the SMC-and VRAM-Reset the crashes disappeared, even with the Power Nap on and with the power plug in.

But the unlock with the watch still didn't work.

After shot down, not restart, the watch an the computer everything is fine. I repeat at least temporarily. The unlock ist working and since the shot downs no crashes with and with out the power plug.

Yeah. Same here... Every morning the same. its annoying. Especially with a 4000+ $ Notebook.

And the usual standard support procedure does not help:

– SMC Reset

– PRAM Reset

– Different users

– Reinstall Catalina without deleting

– Cleaninstall via Net Recovery (with no use of backup)
