I'm in the process of installing an Optibay in my Macbook Pro and have run into 3 really tight screws. They are the 3.3mm Philips that are used to mount the SuperDrive and Bluetooth board. The one on the Bluetooth came out easy but the other three are really tight. I've used the Philips screw drive that came with the Optibay as well as another screwdriver but none of them budge the screws. Anyone have any tips or special method of removing those screws?
