I've been reading sooooo many posts of users complaining about this problem that I'm already backing down on this... I cannot find a word on apple about this. Can anyone tell me is this problem has been taken care of? After all the post I read where all from beginning 2008 ... the problem might have been solved already...or not. Is it really something that is solved by letting the mac on for a couple hours? I read that I will have to put the mac on the room it will be staying for 2 days before turning it on, to let it get used to the temperature. Is this so?
