Catalina Kernel Panic

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.

why apple not fix this? actually there are multiple way to trigger this: plug in with any third party USB device and put into sleep mode will cause this. Also it will also occurs this when I install logitech keypad and mouse driver. Not good

The error occurs when working with the GUI. when switching terminal Windows and applications, in the GarageBand program when you call the drop-down menu. There have been 8-10 kernel panic in the last month

when did Apple fix this?

This is complete nonsense, where is the core protection? where is the software exception? where is the stack error and stack breakdown log? no! hi this is kernel panic %) don't worry so it should be:) great fuckup from Apple!

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.

Same as the above, i.e. kernel panic with com.apple.kext.AMDRadeonX4000(3.0.2) in the middle. Had it three times in the past week or so, twice while the MacBook Pro was sleeping, once while working (typing text in a terminal).

I'm using an external 4K Samsung display on Thunderbolt. I've noticed that the support of external displays and sleeping gets more and more flaky as time goes by. Notably, every time the computer goes to sleep, it's as if the external display was removed and re-connected. All windows move around for a while, re-adjusting to the new resolution. This is especially annoying with XQuartz, which has its own window-manager mimicking macOS, but does not deal with this situation gracefully at all. Typically, it ends up moving windows off-screen, and it's really annoying to pull them all back on screen.

I have been in Sweden for a week now with no kernel panic.

At home it was setup always connected to the Cinema Display. When I come back home I will see if it starts again with the Cinema Display connected.

2015 MPB here, same thing happening. Thought it was just because I did the upgrade. Clean installed Catalina without restoring from time machine, same thing is happening. Ran diagnostic, everything came out okay. Ran first aid on ssd, everything ok. There's other odd behavior as well - for example shutting down can take several minutes, until it finally crashes. When I start up it says it has recovered from a crash.

AFAIK this extension is for SD card readers (which I never use) and doesn't affect other USB peripherals. For instance, I haven't had any issue with external USB drives, or phone & camera since unloading that kernel extension.

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...)

Sorry. You said Norton is ALWAYS the problem and I just wanted to point out not in all cases.

Kaspersky is the only antivirus that plays nice on my system. If it's useless malware, what do you consider great antivirus?

I have the same problem and I have fixed it：https://www.cnblogs.com/nnylee/p/11774950.html

Can anyone read this and make sense of it? It is the latest crash file.

KP now!
