My macbook pro just died.
Futzing around on it and boom. Grey screen. Won't boot. Swapped the old ssd back in to rule that out, same issue.
Called them and there's an extended free repair program on this model (early 2011 15") where the logic board dies.
It means I'll have to re-do a project that was due to be sent out on tuesday, which is a right arse but at least I still have DayZ.
