Hello. I need to completely reinstall Big Sur to Catalina somehow because of how buggy it is with printing and all the other issues. I downloaded something called Catalina patcher, made a bootable usb installer with the program and my other Mac El Capitan boots totally fine with it and able to start installing it. When it comes to my Big Sur it detects the usb drive, starts booting from it and just before the install screen comes up it reboots. After this the computer is stuck in a loop doing this same thing over and over again. Any ideas?
