• Make sure the antenna cables are inserted into their respective notches, as highlighted in the second picture.

Step 31 — Display Assembly

Remove the inner two 4.9 mm T8 Torx screws securing the right display hinge to the upper case.

ℹ️ Leaving the third screw in place for now will aid in rest of the procedure.

Step 32

ℹ️ Open the display so that it is perpendicular to the upper case and place it on a table as shown.

Step 33

While holding the Air steady, remove the remaining 4.9 mm T8 Torx screw from the display bracket.

Step 34

☑ Flip the computer over so the last display screw is more easily accessible.

ℹ️ Before removing the final display screw, be sure to hold the display and upper case steady with your other hand. Failure to do so may allow the components to fall onto the table, causing potentially expensive damage.
