My wife’s MacBook Air was doing that. Took a NVRAM/PRAM reset to make it stop

@hjalm Thanks. I'll give that a try. Hardware diagnostics found 'No Issues". // @rom

Also? Oddly, reporting the restart to Apple seemed to guarantee the reboot more quickly

@hjalm Interested to learn that both resets are not possible on an M1 Mac. discussions.apple.com/thread/25... :

You can’t reset the SMC, because the M1 Mac doesn’t have a System Management Controller. You can’t manually reset the NVRAM / PRAM because your Mac does this automatically, if needed, during every startup.

hmm - now have you tried isolating your suspect (Mail) by not running it for one full day (assuming that you have another device you can use, of course).

@rom This crash was totally unrelated to Mail… I have an older Mac I can use too, so things are open to testing, but for now I'll sit tight and see if today's update has made a difference. I bought this Mac in February so it's still under warranty for a while.

good luck! Hope that you get to isolate it. I know it isn't fun when you are getting random reboots, but make it fun by doing detective and finding out what's wrong. :)

That's a new one for me. I know the M1 begins a new era and I have high hopes. Thanks for this.

@rom Thanks. We'll see… My days of being bothered to do extensive troubleshooting may be over. If it gets worse though…

@hjalm Thank you for taking the time to suggest a possibility. 😀
