Repo for patched IO80211Family Kexts

Legacy Wireless Kexts

Goal of this repo is the following:

• Bring back semi-native support without requiring system modifictaions

To do this, we'll pull the IO80211Family.kext from several versions of macOS, patch their symbols to not conflict with newer versions.

Note: when booting older OSes, there can conflict so we highly recommend users set the MinKernel in your config.plist(Kernel -> Add) to one of the following so the kexts are only injected in the appropriate OSes:

Sierra and newer   = 16.0.0
Mojave and newer   = 18.0.0
Catalina and newer = 19.0.0
Big Sur and newer  = 20.0.0

Special notes

Unsupported Atheros Chipsets

For certain AR9285/7 and AR9280 chipsets, you will need to apply a fake Device ID to your wireless card. This is due to AirPortAtheros40 having internal PCI ID checks meaning simply expanding the device-id list won't work.

Expanding Atheros Support

To add support, grab gfxutil and run the following:

/path/to/gfxutil | grep -i "pci168c:002b|pci168c:002e"

This should spit out something like this:

00:1f.6 pci168c:002e /PC00@0/PXSX@1F,6 = PciRoot(0x0)/Pci(0x1F,0x6)

The ending PciRoot(0x0)/Pci(0x1F,0x6) is what you want to add in your config.plist under DeviceProperties -> Add with the following properties:

Key	Type	Value
compatible	String	"pci168c,2a"
device-id	Data	2A000000

BCM4331

Users of the 4331 chipset, note that macOS Big Sur actually still support your card partially, however will require a fake Device ID. This is a more reliable solution than using the patched IO80211 kext, however may break older versions of macOS as the fake ID is always applied in macOS(however DeviceProperties do don't exist in Windows or Linux, so no need to worry with those)

Expanding Broadcom Support

To add support, grab gfxutil and run the following:

/path/to/gfxutil | grep -i "14e4:4331"

This should spit out something like this:

00:1f.6 14e4:4331 /PC00@0/PXSX@1F,6 = PciRoot(0x0)/Pci(0x1F,0x6)

The ending PciRoot(0x0)/Pci(0x1F,0x6) is what you want to add in your config.plist under DeviceProperties -> Add with the following properties:

Key	Type	Value
compatible	String	"pci14e4,43ba"
device-id	Data	BA430000

io80211-patches's Issues

Will support Big Sur？

High Sierra kexts on Monterey

When using the High Sierra kexts on Monterey, my PC reboots after PCI initialisation completes. I have no issues on Big Sur.

I have an Atheros AR9227.

is there a Patched big sur Kext in?

for the pci14e4,43ba that is spoofed?

Not working on Big Sur with Macbook Pro 13 Early 2013

I'm using OpenCore 0.6.3 with Big Sur on a Macbook Pro 13 Early 2013 and tried to fake the Device ID as well as using the patched kext. Neither of those actually worked, so I was wondering if there is some kind of other workaround?
This has been the output of gfxutil:
03:00.0 14e4:4331 /PCI0@0/RP02@1C,1/ARPT@0 = PciRoot(0x0)/Pci(0x1C,0x1)/Pci(0x0,0x0)
