Unable to boot in recovery mode or reset NVRAM or Pram
I have a 2013 Macbook air that I did an erase and reinstall. Everything booted up fine. The next morning I got the question mark Icon at start-up.
I then powered down and re-booted in Recovery mode. Nothing. Black screen. Went through the NVRAM/PRAM process (command, option P+R) at startup.
Screen blinks as it chimes, blinks again at second chime. Still have black screen.
Cette question est-elle utile ?
