Catalina Kernel Panic

Same problem occurred on my iMac. I solved by getting rid of the googlesoftwareupdate that was occurring constantly and hanging up my system, after that it has been running fine. Here is the information I found to do so.

Good luck.

I fixed a Kernel Panic on my Macbook Pro by downgrading Microsoft Word from 16.31 to 16.29. This may work for you if you use Word.

Search in the MS Support for instructions. Many people are experiencing the same issue with macOS 10.15.1 and MS Word 16.31.

Uninstall Kaspersky. Follow the developer's instructions or use their uninstaller.

If the crashes continue with it uninstalled, you can reinstall it, but it isn't doing anything useful.

Curious if anyone has tried turning off Handoff?

( System Preferences > General > Allow Handoff between the Mac and your iCloud devices )

I remember having an issue with Mojave (I don't remember what the specific issue was, unfortunately...) but the solution was to turn off Handoff...

When I upgraded to Catalina though, one of the steps for setting up Sidecar to use with my iPad Pro was to make sure Handoff was turned on... So, I took a chance -- hoping that Apple had fixed whatever problem it was that I was having -- and turned Handoff back on...

It dawned on me earlier today that perhaps there is still some kind of issue with Handoff, so I just turned it back off. Then I left my computer for a bit, and for the first time since I upgraded to Catalina, there was no kernel panic when I came back! Not sure if it was a fluke, but it truly was the only time it didn't crash when it went to sleep on its own.

I'll report back if things continue to go well, or if it crashes again... Let me know if anyone else has success with this...

(Of course it will be really disappointing if it means that Sidecar won't work with the iPad then...)

I unplugged the time machine backup disc that was connected through Thunderbolt. No KP this night. We'll see. I will try that through the day to see if it has anything to do with that.

I eventually had to do a clean reinstall of macOS Catalina to fix it

I think it is resolved for my part. I read in another thread about deleting the AppleAHCIPort.kext from S/L/E. So I did two days ago and I haven't had a kernel panic since. I have even mounted the Time Machine disc again and still no KP.

yes !

disabled the animation of icons in the panel and the kernel panic was not for 4 days

I got pounded with kernel panics, I think every few minutes, on my MacBook Pro Retina Early 2015. Can't post specific error messages because I just eventually erased and clean installed Mojave. I had put in a new OWC Aura X2 SSD (1TB) just a few days before and wondered if I had a bad SSD or Catalina didn't like it. I'm afraid I just have the one machine and couldn't afford to fight with resolving it.

Been using Macs since my Macintosh Plus and OS 6; this is not the first time I've reinstalled a system by any means but I think the first time I've actually had to downgrade in the last 30 years. :( That being said, I'm sure Catalina is the problem, as things are happy again with 10.14. Anyone know when the first dot upgrade is expected? I may throw caution to the wind and try it again.

I have so far (fingers crossed) not had a Kernel Panic since I unplugged the Thunderbolt Time Machine disc. I also deleted the AppleAHCIPort.kext from S/L/E yesterday.

It started when I upgraded to Catalina. When I load from the non-Catalina partition there is no KP.

The solution for me has been to manually unload the AppleUSBCardReader kernel extension. Open Terminal and type:

sudo kextunload -b com.apple.driver.AppleUSBCardReader

i am fixed KP

use /bin/zsh in system settings

That was my problem, I discovered. I removed those Norton-related kexts and I stopped having the kernel panics. That's all I did - no system resinstall or anything.
