How to Remove the Casing From a Mac (9 Steps)

Locate the lever. On the Mac Pro, there is a lever that needs to be positioned correctly in order to remove the case. The lever is rectangular in shape, positioned vertically, and sits flush with the face of the back panel.
Flip the lever. Apply pressure on the top portion of the lever with your thumb. This will cause the bottom portion of the lever to pop outward from the case. Pull out on the bottom portion until you feel a light snap. This is a sign that the locking mechanism has been released. The lever should stay in the outward position that it is currently in.
Fold down the side panel. The removable side panel is located on the same side of the Mac Pro as the lever. You may have to lift the panel up slightly and pull outward to release it from the rest of the case. The side panel should now be completely free and positioned where you can easily lift it away from the rest of the case.
