    • Power down your Mac mini, disconnect all of the cables, and flip it over.

    • Gently bend the Jimmy outwards to pry the crack open a little larger and lift the lower housing up a small amount.

    • There are several plastic clips on the lower housing that fit into a channel in the aluminum top housing. Your goal is to use the Jimmy to push these clips inward enough to free them from the channel, while gently pulling up on the lower housing.

    • Slightly squeeze the two retaining arms toward each other and lift the AirPort antenna off its post.

    • Squeezing the two posts excessively will surely break them off the internal frame. Work delicately.

    • During reinstallation, you will have to slightly squeeze the two posts together so they fit into the openings on the AirPort antenna board.
