I am about to start throwing things. I'm trying to get into my wife's MBP to upgrade the memory. None of my tools can undo the screws......Am I just screwed? Do I need to take it into an apple store and pay them to do it? I read online that I need some special screwdrivers I've never heard of....will these do? http://amzn.to/yR25lf Any other options?
