My MacBook has completely frozen! Its brand new and i've only had it for about a month, and the whole thing has just suddenly frozen! I think it might be to do with the fact that it's really hot weather today, and i was in one of the hottest rooms in the house charging it and using it at the same time - may have been too much for it to handle. But now my question is...what the heck do i do? I've moved it to a much cooler room, but so far it's had no effect. Also, i don't know if there is a way to shut down the MacBook other than manually clicking the apple button etc. Nothing i key in works, the whole screen is just....frozen, like i say. Sorry i'm repeating myself, just a bit panicked. Any help would be greatly appreciated!
