Use this guide to replace a faulty logic board in your MacBook Air 13" early 2018.

Be sure to apply a new layer of thermal paste before reinstalling your heat sink on your new logic board.

    • Before proceeding, power down your MacBook. Close the display and lay it on a soft surface, top-side down.

    • Use a P5 Pentalobe driver to remove ten screws securing the lower case, of the following lengths:

    • Two 9 mm screws

    • Eight 2.6 mm screws

    • To ensure that everything is de-energized and won't turn on while you're working, it is recommended that you disconnect the battery.

    • Grab the clear plastic pull tab attached to the battery connector and pull it parallel to the board toward the front edge of the Air.

    • Do not lift upward on the connector as you disconnect it or you risk damage to the connector socket.

    • When reassembling your device, be sure the heat sink's rubber gasket is installed correctly. The nub on the gasket should mate with the hole cut into the logic board near the heat sink fins.

    • The tail of the gasket should fit into the notch in the heat sink, it should not end up underneath the heat sink tab that will rest on the logic board.

    • Make sure the antenna cables are inserted into their respective notches on the logic board, as highlighted in the last picture.

Can you use an 2017 logic board onto a MacBook Air 2014 “body” (13”)? Airs from 2013 to 2017 seems to be aboud the same CPU and all others parts are the sam also.

Do you have any video of this case working?

Great guide, worked like a charm. I just swapped out the logic board from a cosmetically destroyed (case and screen only) MacBook Air 2017 i7, into a cosmetically perfect i5 model that has logic board issues which I purchased on eBay. Works perfectly. Thank you!
