Hi guys, I was watching a movie on my macbook pro when the screen froze. Http://postimg.org/image/xna0zt5av/37037adc/ I've restarted it in safe mode, which works, but unfortunately when I restart it normally again it goes back to the frozen screen. (In safe mode it says there is no airport card installed and it doesn't seem to recognise my usb and my phone. Please help!!!
