I have a 2013 trash can, Catalina kernel panics non stop every 2 hours. Googling around and I found so many others with issues. I got the fan app and cranked the fans full blast thinking it was over heating, I even tore the system down and replaced the thermal paste and cleaned it down, and all I did was drop the idle temp by 1 degree, but still constant kernel panics. I downgraded to Mojave as I wanted 32bit back, and as a last try before I just gut it for CPU and RAM, and it’ll run for weeks at a time, with me moving, and updates the only thing that had me reboot or shut down. There is no QA at Apple, they clearly never tested Catalina on a 2013 Mac Pro.
