How can I tighten loose screen on MacBook Air Mid 2013 11-inch
I have seen a video on how to tighten the screws on Macbook Air 11-inch 2013, however, exactly which screwdriver do I need. I already have a wiha P4, which removes the screws on the back of the Macbook. The video says use a T8 screwdriver on the hinge screws. Wiha and other vendors sell a T8 40mm and T8 60 mm. I don’t know which to buy. Don’t know what 40 mm pertains to. Anyone?
