I have a Genius Bar appointment to fix a bezel chip and my macbook, and while I'm there is there anything else they can do to "tune up" the computer? Around buying it I thought I remembered something/one saying that you should take it in once a year for them to do some sort of "cleanup/tune up" type thing. As I live 2 hrs away from the nearest Apple Store I just wanted to know if they can before I go, thanks
