Introduction

Use this guide to replace the antenna bar in your MacBook Pro 14" 2021.

For your safety, discharge the battery below 25% before disassembling your MacBook. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

Some photos in this guide are from a different model and may contain slight visual discrepancies, but they won't affect the guide procedure.

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

    • Use a P5 Pentalobe driver to remove eight screws securing the lower case:

    • Four 9.3 mm screws

    • Four 5 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 device.
