How to Enable Atheros WiFi on macOS [Clover/OpenCore]

By following this guide, you'll be able to enable Atheros WiFi on macOS using Clover or OpenCore Bootloader.

Overview


Back in the day, Apple used Atheros based WiFi Cards in its Mac lineups but Apple dropped the support for Atheros based WiFi Cards with the release of macOS Mojave. However, it is still possible to use the compatible Atheros based Cards on new macOS versions (up to Big Sur). Note that this is not the ideal solution and we recommend you to install a compatible WiFi/BT Card for full functionality.

Compatibility


Refer to the thread linked below for more information on Atheros WiFi compatibility.

WiFi HardwareCompatible Atheros WiFi
Network KextsOriginal Network kexts in S/L/E
macOS VersionmacOS High Sierra and Later

QUICK INFO:
  • This guide is limited to macOS Big Sur only. The kexts do not load on macOS Monterey and later.

STEP 1: Add Required Kext


To enable the WiFi support, you'll need to add HS80211Family.kext and one of the AirPortAtheros40.kext. These two kexts are needed together to work in conjunction in order to enable the WiFi.

1. Download HS80211Family and AirPortAtheros40 from the downloads section of this forum.
2. Mount your ESP.

For Clover:
If you're using Clover, copy both the kexts to EFI/Clover/Kext/Others

For OpenCore:
If you're using OpenCore, copy both the kexts to EFI/OC/Kexts. You'll also need to add the kext entries in the Kernel section of your config.plist.


NOTES:
  • If the kext is already present in the directory, replace them with a new version
  • For OpenCore, HS80211Family.kext should load first and AirPortAtheros40.kext just after

STEP 2: Restart your System


After performing all the above steps, restart your system for the applied changes to take effect.
You can see a WiFi icon in the menu bar now. If not, you can enable it from System Preferences>Network>WiFi>Show Wi-Fi status in the menu bar.
