Estimated Time: 10 minutes
Step 1: Shut down the computer and remove the bottom lid.
Step 2: Unplug the battery and disconnect the antennas and flat flex cable from the original AirPort card. To disconnect the flat flex cable from the AirPort card, you will need to peel back the black EMI tape that covers the top of the connector. Discard the EMI tape, as it's not needed. Be very careful! The antenna and flat flex connectors are fragile; it is best to use a blunt plastic 'spudger' tool to unplug these connectors.
Step 3a: Remove the original AirPort card and bracket.
Step 3b: For 13" MacBook Pro owners only, install the included bracket that came with your order in the location where the original AirPort bracket was secured to the chassis. Use the two screws from the original AirPort bracket to secure the new bracket to the MacBook Pro's chassis. This bracket serves as a fastening point for one of the screws for the bottom lid. To secure the subwoofer, you can place a thin piece of double-sided tape underneath the end of the subwoofer where the two holes are located to secure it to the optical drive.
Step 4: Gently plug in the flat flex cable into the new 802.11ac card.
Step 5: Place the card down on top of the optical drive where the original AirPort card was located. You can now secure the card using thin tape to the optical drive to keep the card from moving around.
Step 6: Plug the three shortest antennas into the new 802.11ac card and plug the battery back in. Note: If your MacBook Pro came with four antennas, simply tuck the longest one out of the away, as this is not needed anymore because the Bluetooth antenna is integrated into the wireless card itself.
Step 7: Making sure not to pinch any wires, reinstall the bottom lid and enjoy faster wireless speeds and macOS Continuity features!
