M1 MacBook Air with external monitor crashes when sleeping

Just happened now, one time.

MacBook Air M1, with a 4K Dell 27" UP2720Q connected by thunderbolt. Not ultrawide. Maybe thunderbolt is the common cause?

Macbook lid closed, using external display + keybpard + mouse. Have worked great few days, but setup is very recent. Will keep posted of findings or settings that can help.

Anyone else installed 11.2 beta 2? I did one quick test this morning with no crash BUT I had to open the lid and login before getting the external monitor back to life. My laptop was also clunky/slow for a bit after. Anyway... pretty disapointed by the situation.

@philgeorge nothing yet! Still not sure if it’s the never sleep setting or if it’s the let google be your email handler setting. I have some critical meetings today but after, I’ll mess around and test further.

I am having the similar issue.

Both M1 MacBook Pro and M1 MacBook Air suddenly crash and reboot itself during normal use (not from Sleeping mode) with an external Acer monitor connected through a hub. The M1 MBP crashes more often than the M1 MBA. So, I returned MBP.

In addition, after wakening from Sleeping mode, the mouse cursor on the display of MBP or MBA often points to very different location than the mouse cursor on the external monitor. It is very confusing.

Very disappointed with the defects of M1 MacBook!

I have the MBP M1 connected to an external monitor and most of the time when I wake from sleep mode and attempt to log in, I get the pink screen briefly, and then it restarts. Brand new machine. I have not tried to replicate without the external monitor but it seems others are having the same issue and reporting it with the monitor connected. Any insight?

More and more users are having this same issue with new M1 MBA. This community has not found out a viable solution to resolve the issue.

Hope that Apple engineers will pay immediate attention to this problem and get this defect fixed ASAP.

therighttread - you describe my issue exactly. I posted to this earlier with the issue, as well as others, and ended up wiping the M1 MBP and starting over. I brought over files from a backup but started fresh with settings and applications. I am using a dock to connect various devices, including an external monitor, and still have it rebooting at night, a few days a week. It is not every day like you mentioned.

I have a 2017 MBP that was used before this running 11.1 and essentially all of the same applications. If I plug that into the dock and monitor it will never reboot unless I do it myself. The issue is with the M1 machine and I cannot believe it is an application that is causing this. I updated the M1 to 11.2 and am still experiencing the issue. It is hard for me to believe that Apple has yet to reproduce this or acknowledge the issue given the many threads here and elsewhere online.

I have also updated as well. I saw a post where someone said that if you have it sleep at night with the old-fashioned charger, it may stop the issue. I'm trying it this evening. Because it is sporadic (it's been three days since the last crash) and happens at the same time-- consistently, I'm perplexed.. I'm not happy about having to wipe my mac clean and start over with slow merging onto my computer, which I need for work 7 day/week.

BTW, I also have tried going through a CalDigit SoHo, CalDigit Mini, CalDigit USB-C Gen2, and Anker HDMI "dock". I have had power delivery via the monitor AND via the Apple wall charger.

Every. single. time. Night terrors.

Yep... sorry, this was a cross post (details in my other post). I used many different docks as well as straight to the wall charger + TB3. I also set the system preferences to never put the display to sleep when plugged in... which did absolutely nothing except give me heartburn towards the longevity of my $1600 display.

I'm guessing that the panic caller id is going to have a different specific address, but it's the same... see my message post from 1/19 (this is the same panic I keep getting, but different cpu caller address).

RTKit, Mailbox, Inbox, Outbox, all remain consistent in the panic, although not really sure what those are in reference to...

panic(cpu 1 caller 0xfffffe002014fe28): ACIO1 Recoverable Panic - assert_id=1437 - ACIO main workloop(3)

assert_id=1437

For some reason, the post won't allow for me to copy-and-paste parts of the report. However, there must be a solution other than dumping my 2500.00 brand new computer. I had a 2016 that worked perfectly with two dell monitors, a caldigit, etc. Not one problem--

Oh, for what it's worth, when I first received the M1, I was connected via KVM to an LG 34 inch monitor over HDMI (via an Anker usb-c dock). I did NOT get a panic crash overnight with this configuration.

This started happening when I got my LG 38WN95C-W and I connected via TB3 to the monitor. I also tried via a ConnectPro KVM <=> DVI <=> (various CalDigit docks).

Just to add my experience to the thread, my MacBook Air purchased in October 2020 crashes often when plugged into a Dell external monitor. The monitor's HDMI cord is plugged into an adapter, which is plugged into the lightning port on the computer. Super frustrating issue and really limits what I can do working from home with one little laptop screen. Not sure if it would fix the issue if I purchased a newer monitor or one that connects directly to the computer, but it seems like an expensive fix for a new computer.

The error I get is "Intel CrashLog recorded due to unexpected reset" when I turn my computer back on. Wasted hours on the phone with Apple and after taking it into them for 5 days to get fixed (and working off a 7 year old PC in the meantime with no issues). They told me it was a corrupt application on my computer so they wiped and reinstalled everything. Within 20 minutes of using it again, the system crashed again.

Does Apple normally respond to these threads? Never used them before...and this seems like a pretty broadly hit issue. I understand it takes companies time to reproduce, fix, and validate the fix before pushing it out. It would be nice to at least get an Ack from Apple.
