There are three screws in the back of my white Keyboard on my 2.66GHZ MacPro. I have a bunch of Torx wrenches and other computer tools where I thought would unscrew the 3 screws on the back of the keyboard so that I could remove the crud built up between the front keys and the transparent plastic. Can anyone tell me what I need to use to unscrew the three back screws so I can clean the stuff out.
