I was trying to get to the heatsink of my 13" MacBook Pro (mid-2009) so I can change the thermal paste, and the last screw on the motherboard got stripped. It is the 3.9 mm phillips screw in the lower left hand corner, and I was using a #00 phillips screwdriver with it. Any ideas for removing it? This is a laptop I use for school so I would like to try to fix this issue with no collateral damage, if possibe. Thanks!
