I dropped my MacBook Pro (Retina, 15-inch, Mid 2012) on it’s corner. It didn’t cause any internal damage – the computer worked normally – but the the lid (with the display) became misaligned.
The misalignment made the lower right corner of the display scrape against the base of the computer whenever the display was opened. I thought if I could loosen the screws that held the display, I could realign the display with the base of the computer.
I used iFixit’s MacBook Pro 15″ Unibody Mid 2012 Display Replacement (by Andrew Optimus Goldberg (and 5 other contributors) as a guide to remove the lower case and to get to the six 6mm T6 Torx screws holding the display (there are three in each corner).
The repair is fairly straightforward. The only tools that I needed were a Phillips 00 Screwdriver
1. Remove the lower case. (10 Phillips screws)
2. – Note: the links to the following two iFixit links are to illustrate the location of the screws – the screws shouldn’t be removed.
Slightly loosen (do not remove !) all six (three on the left corner and three on the right corner) 6mm T6 Torx screws holding the display to the upper case.
3. Close the lid and move the display so it properly aligned with the computer base (the part that has the keyboard).
4. Tighten the six 6mm T6 Torx screws
5. Reattach the lower case.
