macbook pro 15" 2010 black screen.
it's been a long time now, that those black screens appear whenever i open photoshop or anything heavy graphic-related.
i had it with snow leopard, mountain lion and mavericks. i was able to force the system not to switch graphics with gfxcard status.
the thing is this does not happen in safe boot, so it could be a thrid party issue too.
but there's something new with mavericks, i get glitches under heavy loads even with the integrated mode. i dont't know if it's related or not.
and to continue the bad luck, i live in Iran, there's no technical support or such as the Apple announced they would change the logicboards with this issue free of charge, here.
so my only chance is getting to the third part issue, if that's the case. what possible step could i take to avoiding the black screen?
