hi everyone, ive got a macbook air 128gbssd, and im sure i have the faint grey lines in the background.i can put up with it for now but i just want to know if anyone else has this or have reported to apple. if you google it theres heaps of us threads about it. i rang apple but the jerk on the phone was no help at all. i just want to know that apple will fix my $4k air as for that price it should be perfect!
