Why does my iMac that keeps rebooting after Catalina reinstallation?
My iMac (late 2014 with Intel) failed and recovery let me erase and reinstall Catalina. I reset the login, etc. but in the middle of using the iMac it reboots. I've tried disk utility to do first aid to the data drive. Still reboots. I've read about starting in Safe Mode, but not sure where to go from there. Maybe the iMac is just fried?
