CVM Server Crash / restart in BigSur 11.2 on M1 MacBook Air

Hello adyav,

​Thank you for using the Apple Support Communities. It's definitely important to make sure your Mac is running as expected, and we'll be happy to help. It looks like your MacBook Air M1 is restarting unexpectedly, correct?

To get a few details, how frequently is this happening?

From your post, it looks like it might be happening fairly soon after starting up. Is that right? Is it happening when you use a particular app, or does it vary?

To troubleshoot, you might try booting up into safe mode to see if you can replicate the behavior there. This will help to rule out some software causes. You'll want to use the steps in the "Apple silicon" section of this link: How to use safe mode on your Mac. Let us know how it goes.

Cheers.

Hi adyav,

We appreciate the reply. Were you able to test this in safe mode to see if you can replicate the behavior there? Knowing how it works in safe mode will be a good start in working out what could be causing the issue: How to use safe mode on your Mac

Keep us posted on the results. Those results will help work out possible next steps.

Take care.

adyav,

Thanks for letting us know! It sounds like the issue persists in safe mode as well.

Do you have any peripherals connected to your Mac when the issue occurs, like hard drives, docks, hubs, printers, etc? If so, try disconnecting those and test; does that make a difference?

If not, updating to the latest version of macOS Big Sur is a good next step. Be sure to back up beforehand:

Back up your Mac with Time Machine

How to update the software on your Mac

If the issue persists even after updating and testing without peripherals, see if you can replicate the issue in a newly-created administrator account next. This will tell you if you have a system-wide or user-specific issue, and will help work out a path forward. Here’s how to Set up users, guests, and groups on Mac.

Best wishes.

adyav,

To double-check, it happens both with and without the external monitor connected and you don’t have any other peripherals or devices connected, correct?

Also, were you able to test it out in a new administrator account yet? It sounds like it may take a bit of time to test and determine if the issue happens there or not based on how long you mentioned it took in safe mode; let us know what you find. This information will help work out your next best steps.

Take care.

Same here on an mac mini m1: I get 2 to 3 a day.

Precision:

I have 2 screens attached (one large dell 4k and one small 1k). I have a thunderbolt2 hub + external SSD, external SATA, +10 items connected via a usb hub (from ilok to webcam, mouse, keyboard ...) and an audio interface.

I've just started experiencing these issues as of today (8GB M1 Mac Mini). The only thing that changed is that I added an external drive (G-Technology 2TB USB-C). I have been trying to copy an old external drive (that had FW800 connector for high speed *sad face*) onto this new USB-C drive. I was experiencing crashes transferring from old-drive-to-USBC-drive OR from HDD-to-USBC drive. NOT old-drive-to-HDD. I have had four full reboot crashes with the same Exception Type BUT Exception Code "...100b94000".

By playing around with Disk Utility I discovered that there are two file systems for OSX (I am a Mac novice). So I used Disk Utility to change the USBC drive file format HFS+ to APFS. I am now 15% into a file transfer (old-drive-to-USBC-drive) with no issues touch wood. I was also trying to copy files to the USBC drive from HDD which were getting other errors. So I am wondering if there is a correlation between the file structure and this error?

You note that you are using an external drive. Is it using HFS+? Perhaps try un-mounting it for a day?

So I just copied across a 190GB Photo library and 60GB Logic library from one external drive to another with no crashes. So keep an eye out for external USBC devices using HFS+ seems to be the moral of the story (don't know why)...

I get more or less one crash a day, if I use it more, I get multiple reboot a day. It is unusable for me.
