Hi everybody, I got my Macbook in January and for about 3 months it worked fine. Then it started freezing. When it freezes, I can't force quit out of any application, the only thing that works is a hard reset. Tried repairing permissions, resetting RAM, finally took it to the Apple store. They kept it for a while, replaced the logic board and the airport card, mentioned something about a possible short. I spoke to a tech who said they've passed it around to three different people who couldn't figure out what's wrong with it. Finally got it back on Friday, and while at the store, could not run Safari at all. It would hang with the beach ball spinning. We had to delete my user profile and create a new one. That seemed to work. However, since then, it froze 3 times over the weekend. I am taking it back to the Apple store tomorrow, but is there someone I should talk to meanwhile? Call the store or Apple tech support? Should I ask them to just replace my computer? Side question: I am in NYC. Should I take it to Tekserve instead of Apple? Even if I have already had it repaired at the Apple store? Thanks! Boris By the way, there is no consistent behavior when the freezes occur. Most of the time I am checking email or something internet related, but it has also happened when only iTunes is running and right after startup.
