Why are kernel panics now happening?

I am running a clean, separate Monterey install to gauge whether or not it's worth upgrading to, so I tested if the bug is still there with another TM drive. So far I can't reproduce the bug using the same procedures that cause Big Sur to crash, so I think it is fixed. I'm planning to upgrade at the end of the week unless something comes up.

Hi Kit!

I had several kernel panics for a couple of months both in Big Sur and later in Monterey, but I think I know what caused them. I used to open Adobe programs from 'handmade' shortcuts in the ”dock” (don't know what the ”dock” is called in English, see inserted pic), and I mean alias/shortcuts that I had made myself :

When I updated Adobe programs via Creative Cloud I guess the shortcuts stopped syncing correctly, one by one. The system kept trying to find the older version of the program, and when that wasn't possible it probably caused the kernel panic. My crash logs always said: ”CPU Machine Check Architecture Error Dump”.

Since I removed the shortcuts I haven't had a single system krasch (kernel panic). The last one was almost 2 weeks ago, before removing those shortcuts. My Mac seems to be happy again, and so am I! =)

I hope this is a solution that can help others too! =)

Hi,

I have upgraded to Monterey and it appears not to have the same bug. No crashes so far.

After some community member's confirmation me too moved to Monterey and till today zero kernel panic 😃

I am having the same issue unfortunately. Now causing kernel panics at least twice a day! Very frustrating for obvious work losing reasons. Crash report : "busy timeout[0], (60s): 'AppleAPFSMediaBSDClient'"

System is a M1 Mac mini 2020 running 11.6.2 - only started happening in the last few weeks.

Suspect it is a software issue - any eta on a fix Apple?

I have had the same kernel panic 3 times over the past 5 days. First 2 times were preceded by a screen flash before going dark. Only the most recent was after using TM and then waking from sleep. Mine did not begin until after my photos library became corrupted and I had to restore it from a backup. No third party kexts and using 11.6.2.

Same symptoms. Also started with the move to 11.6.2. Is there a way to back out that upgrade?

I have seen lots of related issues to M1 on the forums. Today we had the system just drop the Ethernet plugged into a belkin hub and refuse to reconnect until we restarted the computer.

i also has a crash when trying to run first aid on a Sandisk external SSD. If completed with no errors and then immediately panicked.

I removed the connection to my Synology backup since this was a third party tool.

I have been told by Apple support that it is not possible to downgrade Big Sur, at least on Apple Silicon. According to Bombich’s CCC help page, if you upgrade to Monterey there is a workaround: https://bombich.com/kb/ccc6/macos-big-sur-known-issues

Also from Bombich Software:

“It has also grown increasingly difficult to make a copy of the operating system. Starting in macOS Big Sur (11.0), the system resides on a cryptographically sealed "Signed System Volume" that can only be copied by an Apple-proprietary utility. That utility is very one-dimensional; choosing to copy the system requires that we sacrifice other backup features, e.g. we cannot copy the system and retain versioned backups of your data. Due to these changes and the limitations of Apple's new "Apple Silicon" platform, creating an external bootable device is not only less approachable for novice users, it's also less likely to serve as a reliable troubleshooting device.”

Well, folks, macOS 11.6.3 is now released. I cannot update yet, so has anyone updated and looked to see if this bug is fixed?

Just updated. The bug is still there. Exact same error, exact same process.

The same for me. 11.6.3 does not fix this.
