Ok, so my MacBook is just under 2 weeks old...and it froze twice already. I was running a bunch of Apple built apps (mail, safari, Pages, etc...) in the background, and the iTunes visualizer was on playing my songs. Twice, the MacBook would hang with the whole computer frozen and the song sounding like a broken record player. This happened twice, same situation causing me to perform a cold reboot. Should I be worried and bring it to the Genius Bar, or am I just being a bit too pushy on the computer with running 3-5 apps and the visualizer at the same time? FYI, its the new Aluminum MacBook, 2 gigs RAM, 250 GB HD Thanks.
