Big Sur 11.3 multiple crashes and restarts a day

I see none of the usual suspects in the report. A good clean report.

Try the following:

#1

Boot into Safe Mode according to Start up your Mac in safe mode - Apple Support and see if the problem persists. Reboot normally and check again.

NOTE: Safe Mode boot can take up to 10 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

If the problem persists:

#2

Boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and repair the disk. If you get any error messages repeat until no errors reported. Reboot normally and test.

If the problem still persists:

#3

Boot into the Recovery volume (boot with the Command + R keys held down) and reinstall the system. This does not affect your user files but it's always wise to have a full and current backup before attempting any of these fixes.

Has one considered some type of problem stemming from you account ? Have you tried making another account ( for test purposes ) and seeing if the same things happen.

Hi ysl1,

I think you should contact apple support or go to the genius bar in the apple store as it might be,

1. Boot up software and/or macOS corrupt or other issue
2. Hardware failure

I am happy to help!

My 2017 MacBook Air just started quiting mail on its own this morning. Had issues for the last 3x months connecting my account, which was fixed by the update, but now this is happening. Only impacts Mail right now (which opens for about 10 seconds then quits again and displays the 'unexpected quit' report), so I hope there isn't still more to come... Have tried the re-start but no change. Will uninstall Chrome (only used for testing) and see what happens as I've seen other topics suggesting this could be the culprit.

Thanks for the feedback.

I have have very similar problems with on an iMac Pro. I've tried all of the things suggested by others in this thread. What was the solution to the firmware issue? How did you/they fix it?

Cheers!

Can you give us more details? Did they fix it? Can I fix it, and if so how? I am not close to a genius bar.

Thanks.

That page appears to be for M1 Macs .... My older Macbookk is crashing. :-(

I too have installed 11.4, unfortunately no change for me, still have the same issues.

Suspicion is that this is due to a firmware change that is incompatible with our (my) hardware. How solution found. I reloaded Catalina, and now it is crashing, too.
