Question: Q: MacBook Pro 16 keeps restarting in sleep

This has also been happening to me for the past week. My computer goes to sleep at night and in the morning I find that it restarted and I have to open all my applications.

I tried reinstalling the most recent version of MacOS last night but my computer still restarted afterwards.

This is part of my error log from this morning:

panic(cpu 2 caller 0xffffff800f016487): "AppleIntelFramebuffer::setPowerState(0xffffff81be07d000 : 0xffffff7f925c0d88, 1 -> 0) timed out after 46006 ms"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6153.101.6/iokit/Kernel/IOServicePM.cpp:5296

Having exactly the same issue. MBP 16 with i7, crashes in the morning when I wake it up, and the error message also says AppleIntelFramebuffer. I've tried restarting the computer before I go to bed, but in the morning it still crashes.

I have the same problem. Just got my new Macbook pro in two days ago switching from a PC and every time I return to my computer I get this message. Starting to regret the switch...

I have exactly the same problem with a Macbook for 16 ... I'm incredibly angry!!!!

What to do about it? I'm a professional and this is starting to make me angry !!!!

I have narrowed my problem down to the power cord. It does not restart when the power cord is not plugged in. Working with Apple support on this now.

I have exactly the same problem and the same conclusion. my computer used to restart every morning. After I started unplugging the cord, I've gone through three days without restarting

Has Apple support been able to address this issue?

my computer finally just stopped restarting. Not sure what changed. I did figure out for myself that the restart was mainly happening when I have an external hub plugged in that has a usb and hdmi connection attached. That’s still attached but not having the problem now so haven’t reached back out to Apple support. I also fiddled with some of the energy saver settings but not sure if that is what helped.

I've noticed this happening within the past few weeks or so on my MBP16, while asleep and connected to power, and I'm using the 96W USB-C Power Adapter and USB-C Charge Cable that it came with. Similar error log, too. Perhaps it's related to a recent software update?

I have the same problem since the last OS update. I have a brand new MBP16 Core i9 with 32GB RAM that worked well for about a month until the latest OS update.

I wrote to Apple and I am sending them the crash reports every morning, but I haven't heard back from them yet. Reminds me of the nasty PC/Microsoft days...not good!

It is a Catalina issue for sure. I managed to isolate it to the use case of this crash occurring when the MBP16 is connected to my external QGeeM USB-C hub, through which I charge my MBP16 and connect to my desktop monitor via HDMI (I disconnected all other USB peripherals from the hub to eliminate any other possible root causes). The MBP16 works flawlessly when it is not connected to external power or the USB-C hub and it goes to sleep and wakes up without a hitch. It will consistently crash and reboot in the AM if it is connected to the USB-C hub overnight.

Apple - we need a new Catalina patch ASAP and your silence is confidence-quenching...please address ASAP! We are losing faith here...

Try another hub, one that is self powered.

I have had the same problem with my 15 inch MBP 2018

I realised, that there are many repeated errors in Console, coming from Safari and Mail. In the night, the connection to the internet is turned off. I suppose these errors made a buffer overrun?

Then I closed Safari and Mail. No restarts in the night anymore.

And one day after an update these errors of Safari and Mail were gone.

Unfortunately I did not save these errors. Could somebody look into Console, click on "Errors and Faults" and report back

Can you recommend one that you are using and not having issues with? Thanks
