Hi Grim62,

If this is the first Kernel Panic, just ignore it. All Macs Panic eventually. If it happening more often, please read the following.

Check your Mac with EtreCheck. EtreCheck is a useful app to diagnose issues, both hardware and software. It is trusted by many users. Please follow the steps outlined below:

Go to the Mac App Store and search for "EtreCheck."
Download it. It is a free and trusted app; as it is on the Mac App Store, and only trusted apps can be submitted.
Run the report, and put it in a post, as seen here - https://discussions.apple.com/docs/DOC-250000211

I think that you should also run Apple Diagnostics - Use Apple Diagnostics to test your Mac - Apple Support

Please post results of both!

Cheers,

Jack
