Salient Posted September 12, 2020 Share Posted September 12, 2020 Booted Catalina with opencore USB, worked OK, some kext missing. Shut down, tried to reboot with Clover, no go... AMI BIOS was no longer functional. Pulled CMOS battery to reset. Why does opencore overwrite / disable CMOS / BIOS? Thanks for an explanation. Don't really want to reset CMOS while tinkering wirh opencore bootloader. Link to comment Share on other sites More sharing options...
