We got my girlfriend a Core2Duo MacBook back in April. After the first boot I noticed that it had shutdown, and would not wake up or turn on until I removed the battery... Fast forward a little over 2 months and the problem is still there. It's not as bad, but she still won't do any important work on it. So I scheduled an appointment with one of the arrogant geniuses in towson, md. All he did was overload the cpu, to see if it would crash... I told him I've already did that. He then tried to repair permissions... Told him that had been taken care of. Then he leaves it to install the newest itunes... What a waste of time. After that he told me the only option was to leave it and allow them to do some "real world testing"... When I inquired what that meant, he told me they would just let it sit idle & perform apple diagnostic testing on it for 2 days. It if it did produce symptoms then they would format the drive... I told him I've already formatted it 3 times. The only software on it other than the base package is adium. So after an hour of listening to this *****, he starts yelling at me and asking me "What do you want me to do"... I told him I want the damn thing fixed. He said the only way they could do that was to do "real world testing"... Now keep in mind I've read almost every forum, and read every log on google on how to fix this stupid thing. And it seems to me if you get a MacBook with the problem there is no fixing it. So here's my solution: Sell the DAMN THING! I'm not going to deal with any more hassles to the mall, no more arrogant geniuses, only for the end result. Apple will scratch the unit up, *they made a mess out of my macbook pro*. And from what I can tell there is no working fix. All in all we will probably lose about 75 dollars. But that's worth dealing with the headache.
