Why is the bottom casing coming off?
On the bottom of my Mac, there is a plastic/rubber sheet that is screwed into the main metal housing. One of the screws is missing, and when i got a new screw to put in, the rubber started peeling off of the edge and there seems to be more rubber than edge, and it doesn't all stay in. I don't want to go to the Apple store because its kind of far away, and i was wondering if i could just do it at home. Please help!
