Hi, been having frequent Kernel Panics several times per week on a 2019 iMac (Intel)
This started happening after upgrading from Catalina to Big Sur several months ago
I recently tried reinstalling the OS and while that seemed to made several apps more snappy and made the system faster overall, the panics still haven't stopped
Not using any kexts or anything special
I know there could be several causes but anyone else have any luck fixing this? Any help would be appreciated
