I just acquired a MacBook Pro 15" with a cracked LCD. I was able to have it run from the external monitor and change it to the primary. Everything worked until i tried to upgrade to Snow Leopard! The default screen reverted to the internal display again, but I have no idea what its displaying!
I'm stuck. Anyone have any idea how I can get myself out of this fix?? (I tried re-booting after waiting for 1.5 hours - just in case, but no go)
Bu iyi bir soru mu?
