My MacBook Pro 15” 2012 Retina screen is completely black. This happened right after I updated to High Sierra. I tried doing all the resets, and at some point I realized that I could flashlight the screen from behind the logo, so I tried more things. Suddenly the screen turned on when I turned on the computer, and I could see the apple logo, but then it went black again - and now I can’t see the screen when I put a flashlight to it, for some reason.
Does anyone know what I can do? Or alternatively, is there a way for me to screenshare with AirPlay that I can access without being able to see the screen?
