# When and what kexts to use

# Broadcom

# AirportBrcmFixup

This is needed to fix wifi on many Broadcom cards, while not all of them need them it's generally required when using non-apple manufactured wireless cards. This also has the added functionality of injecting old Broadcom kexts into newer versions of macOS.

Note:

  • Apple Airport and Fenvi cards do not need this kext

# BrcmPatchRAM

Required for all non-apple manufactured wireless cards due to how Firmware is handled. This is actually a bundle of multiple kexts:

  • BrcmBluetoothInjector
  • BrcmFirmwareData
  • BrcmPatchRAM fix:
    • BrcmPatchRAM3 for 10.14+ (must be paired with BrcmBluetoothInjector)
    • BrcmPatchRAM2 for 10.11-10.14
    • BrcmPatchRAM for 10.10 or older

Note:

  • Apple Airport and Fenvi cards do not need these kexts
  • OpenCore order is alphabetical: Injector -> Data -> RAM

# Intel

# itlwm

Currently does connect and even support Apple's own IO80211 framework(via AirportItlwm), unfortunately doesn't support Airdrop, see here for features and limitations: OpenIntelWireless

# IntelBluetoothFirmware

Adds Bluetooth support to macOS when paired with an Intel wireless card

# Atheros

# High Sierra's IO80211Family

This kext is required for all Atheros chipsets that had support dropped in Mojave, these include:

  • AR242x
  • AR542x
  • AR5416
  • AR5418
  • AR9280 - AR5BHB92
  • AR9285 - AR5B95
  • AR9287 - AR5B97
  • AR9380 - AR5BXB112

# ATH9KFixup

To be paired with AirPortAtheros40 to fix support for many unsupported Atheros cards, similar idea to AirportBrcmFixup:

  • AR946X (AR9462 & AR9463)
  • AR9485
  • AR9565

# AthBluetoothFirmware

Required to ensure Bluetooth firmware is loaded correctly in macOS
