Ok so this is my issue..I was trying to unscrew the screw to replace the harddrive but I had the wrong screw driver so the screw lost a tab bit of it's shape.then I bought the right 00philips screw or w.e it's called and when I was trying to unscrew it, it lost it's shape and now I can't unscrew the damn screw. I honestly don't know what to do, would apple help with that or bestbuy(since bought it in best buy) would they just tell me it can't be fixed? Because I need this new hardrive which as the neccesary storage for my personal use... Oh and I have the late 2008 model MacBook
