My MacBook Pro Retina 2013 has a Dead Pixel
I just noticed my MacBook Pro Retina has a dead pixel in it. It is black then changes to white when on a black screen. (It's just one) It just came out of no where, and I wanted to know if I was still in Warranty? And if not how mush would it cost to repair it?
MacBook Pro with Retina display, Mac OS X (10.7.4)
