Two screws with a short threaded portion near the hinges
-
Two screws with a long threaded portion near the front of the MacBook
-
-
-
Apply a suction handle to the center of the lower case's front edge.
-
Pull up on the suction handle with strong, steady force to create a small gap between the lower case and the frame.
-
Insert an opening pick into the gap.
-
-
-
Slide the opening pick around the bottom right corner and three quarters of the way up the right edge to release the second clip.
-
-
-
Insert the opening pick in the original gap created in the middle of the front edge.

Slide the opening pick to the bottom left corner to release the third clip.
-

-
Remove the lower case.
-
Set it in place and align the sliding tabs near the display hinge. Press down and slide the cover toward the hinge. It should stop sliding as the tabs engage.
-
When the sliding tabs are fully engaged and the lower case looks correctly aligned, press down firmly to engage the hidden clips underneath. You should hear and feel four distinct clicks as they snap back into place.
