3.Locate the black tabs at each side of the plastic optical drive mounting bracket. Starting at the release tab that is furthest from the logic board, grasp the tab with needlenose pliers, and flex the tab toward the optical drive flexible cable. (Note: This graphic shows a different iMac model, but the removal procedure is the same for each model.) Use one finger underneath the edge of the optical drive to gently lift up that corner of the drive.
Caution: Never press down on or grasp the body (silver) of the optical drive when removing or installing it. Depressing the body of the optical drive could damage the mechanism. Grasp the optical drive by its mounting bracket only.
