Experiencing frequent kernel panics

I have recently been experiencing frequent unexpected restarts of my MacBook Pro 2019 as a result of kernel panics. Despite trying various troubleshooting steps, I am unable to identify the issue, or reproduce the issue on demand. Is anyone able to provide me with any suggestions as to the cause based on the crash log provided?


Any suggestions as to the possible cause of my issue, or ideas on how it can be resolved, would be greatly appreciated.


Thanks

MacBook Pro 13″, macOS 12.3

Hi gambler98!


I would for sure uninstall Mac Cleaner 2. There are other developers SW installed such as Tunnel Bear, and more but MacCleaner2 would be my first guess. If you can’t Uninstall it, it’s components are usually in the file path shown: /Library/ typically /Application Support, Extensions, Internet Plug-ins, Launch Agents, Launch Daemons and Startup Items, you can remove any files from this developer here and restart your Mac to test. (Of course you’d also want to delete it from /Applications/, and remove it from System Preferences > Users and Groups > Login Items, before restarting. Again this is all if you can’t uninstall it, it won’t uninstall, or it’s just being super stubborn! Cheers.

CATERR = catastrophic error condition, asserted by the processor

Kernel Panics are predominately caused by hardware faults or faulty third-party kernel extensions.




Uninstall all third party apps that are Cleaners/Optimizers/Anti-Virus/VPN

all known to cause issues on the macOS



Kernel Panic reports can be found /Library/Logs/DiagnosticReports

From the Finder>Go>Go To Folder, copy and paste:

ends in .panic you can post the whole report in the "Additional txt" box below

Kernel panics are predominately caused by third-party kernel extensions (system modifications) and hardware faults.

There are some other rare causes, one of which is related to NVRAM, so resetting NVRAM may help.

You'll see loaded kernel extensions listed under the "loaded kexts" section of a panic log. I don't see that in your posted log.


If you get a panic log that has third-party kernel extensions in the loaded kexts section, uninstall them following the developer's instructions or uninstaller tool.

If you don't have any, or removing them doesn't fix the issue, it is most likely a hardware fault. Take it to an Apple Store Genius Bar or Authorized Repair center for evaluation. Except for RAM issues, Apple Diagnostics will almost never find the cause of a kernel panic. It only looks at major subsystems.

This looks like it is probably a hardware problem, but most of us cannot read much into these panic reports - they are more for developers.

Please run Etrecheck and post its full report here. Use the "additional text" button and paste the report into the text box.

This will tell us more about your hardware and software and may shed some light into possible causes.
