Hello, lately my 2012 Macbook Pro Retina has been having a hard time of it.
When it boots up, the display is totally black. I've discovered a workaround in that if I plug an external thunderbolt display in and out a few times, the screen will miraculously come to life (until I shut it down again.)
Speaking of external dispalys, none will work - not from thunderbolt or HDMI. No deteciton, no nothing.
Everything's up to date, tried resetting SMC and PRAM. Running out of ideas. Anyone else experienced this?
