Cool! Alls ya hafta do is take a sewing pin or needle and push it between the apple and the computer. I prefer where the apple curves right above the bite mark. Push the needle down and that should pry the apple right off. Its only stuck on with glue. (I had to get good at it when I ran around my school prying them off computers they were throwing out
) Mac performas, etc. have smaller apples, while classics and older ones have big ones. That's pretty much it.
