I am going to be buying a MacBook soon. I would like to know how to maintain OS X and the Exterior of the MacBook. What I'm saying is, on XP, I maintain it by regularly running CCleaner to remove caches, internet history, and to clean up the registry. I also use McAfee to "clean up my PC"... and although I'm not sure what it does it makes it fast. Also, I'm assuming my MacBook will get grimy from use, so can I just take some windex to it? Thank in advance.
