Introduction

Use this guide to remove or replace the antenna bar in a Late 2020 MacBook Air (M1).

    • Before starting this procedure, you should disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide to disable Auto Boot.

    • If your MacBook is running Big Sur v11.1 or later, disabling Auto Boot may not work. You can proceed normally, but make sure to disconnect the battery as soon as you're inside.

    • Completely power off and unplug your MacBook before you start. Close the display and flip the entire laptop upside-down.

    • Use a P5 driver to remove the following screws:

    • Two 7.9 mm screws

    • Two 7.3 mm screws

    • Six 2.6 mm screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your MacBook.

    ESD safe mat, plugged into ground, with a wrist strap, also grounded, are the best best to protect the logic board.

    • Wedge your fingers between the display and the lower case and pull upward to pop off the lower case.

    • Remove the lower case.

    • To reinstall the lower case:

    • Set it in place and press firmly to engage the two hidden clips underneath. You should feel and hear them snap into place.

    • Use the flat end of a spudger to pry up and unlatch the metal locking arm on the battery connector.

    • Make sure the metal arm is completely free of the locking tab before lifting the battery connector. The metal locking arm should easily unlatch.

    • Lift straight up on the metal locking arm to pull the battery connector out of its socket on the logic board.

    • During reassembly, press the battery connector straight down into its socket, making sure it sits flush within the socket.

    • Use a T3 Torx driver to remove the 1.4 mm screw securing the antenna cable cover.

    • If your T3 bit feels a bit too loose, you may need to use a T4.

    I needed a T4 for this

    Wiha tools T3 fit perfectly.

    • Remove the antenna cable cover.

    Make sure the 90 degree bend on the cover is towards the hinge when reassembling. It will fit in backwards, but will cause problems.

    • Use a pair of tweezers to grip the antenna connector close to its base.

    • Pull straight up to disconnect the cable.

    • Repeat for the second antenna cable.

    These are tiny, and hard to reconnect. The key was to position the cables so their ends are very close to the posts on the board.

    • Use a T3 Torx driver to remove the two 1.5 mm screws securing the display cable connector cover.

    None of the screws in this repair are T3. All the smaller ones are T4. Which is good, ‘cause my (cheap) repair tool kit doesn’t have a T3.

    The T3 screws called out were indeed T3, not T4 on the MacBook Air I replaced the display on.

    I dropped one of these - can they be purchased? Or is there a matching screw in an older MacBook Air? I have a ton of those for parts... :-)

    • Remove the display cable connector cover.

    • Use the flat end of a spudger to pry the display cable connector straight off of the antenna board to disconnect it.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

    Since this step is the most crucial in the reassembly process I suggest connecting the flat cable to the board BEFORE placing the board in to its cavity in the antenna bar. MUCH easier and SAFER to do.

    • Use a T5 Torx driver to remove the six screws securing the antenna bar:

    • Four 7.4 mm silver screws

    • Two 4.7 mm black screws

    Mine here is T6 Torx not T5.

    When putting it back together, make sure to get the display cable connector out from under the antenna board before screwing the antenna bar back down. The connector has to go behind the bar in the little notch as the board goes through the opening in the bar.

    • Insert the pointed end of a spudger into the gap between the antenna bar and display hinge.

    • Pivot the spudger against the hinge to pry up the end of the antenna bar.

    • Repeat for the other end of the antenna bar.

    • Use your fingers to pry the antenna bar straight up and away from the case.

    • The antenna bar is secured with some adhesive and may require some force to dislodge.

    • Thread the antenna board through the opening in the middle of the antenna bar.

    • Be careful to not put any strain on the antenna bar's ribbon cables.

    • Remove the antenna bar.

    Separating antennae bar from case after removing screws is challenging. Author’s directions are good but what needs to be addressed is a thin strip of adhesive on both sides of the bar that needs to be separated. the strips are located on the hinge edge of the logic board mount area. I used a metal, razor thin, wide, blade type spudger to gently “wedge” underneath the bar along both adhesive strips to loosen the bar and lift it up. Careful!

    Thanks for this hint!!

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
