I am on a unibody Macbook Pro, and I recently purchased 4GB RAM from OWC. I used a Philips 00 screwdriver which succeeded to unscrew 2-3 screws and I used a Philips 0 to get out another 2-3. However, there is one screw that refuses to move, despite using the correct screwdriver and applying plenty of donward pressure to increase friction. The screwhead has been damaged because of my efforts; it's not the worst stripped screw I have seen, but bad nonetheless. Also, there are 2 non-damaged screws that will not screw in all the way. I have made a Genius appointment at my local Apple Store. Do you think they will be of help? I'm not asking them to install 3rd party RAM, just remove my stripped screw and perhaps give me a few replacements. I am still under warranty. Do you think they can help me? I am willing to pay if need be. Also, do you have any other suggestions for me? Thank you.
