Anyone else noticing their new macbook air freezing randomly and the screen just turns completely black? The back light is still on but nothing is on the screen. None of the buttons work, can't force quit anything, i have to hold power button to turn it off then back on. It has happened to me twice already, first time when i was installing the adobe suite, second time is when I was working on a school assignment with a simulation app (not cpu or memory intensive AT ALL). Console Viewer doesn't show anything. Just wanted to see if anyone else is having this problem or if it's just me. I'm going to try and use it a bit more to see if I can get it to happen again.
