I have just installed a new logic board and an SSD on my late 2014 Mac mini. When I turn the computer on, a blinking folder with a question mark appears and I can get no further. What should I do next
I have just installed a new logic board and upgraded from an HDD to a SDD on my late 2014 Mac mini. When I turn the computer on, a flashing folder with a question mark appears. I held down the command + R key but nothing happens. What do I try next? We are trying to download a new operating system and I do have a Time Machine backup
Mac mini, 10.15
