Broadcom WiFi/Bluetooth [Guide]

Care to post a copy of the script you are using, so we can see what it does contain.
 
Hi Guys,

I have a small problem.
I have installed Big Sur 11.5.2 with OpenCore 0.77 on my HP EliteDesk 800 G3 DM with a M.2 BCM43224:
  • Bluetooth only was working
  • Wifi chip is not supported anymore by Big Sur (tried several proposed workaround with no luck)
I replaced the BCM43224 by a BCM94360CS2 (Apple MacBook Air Airport card):
  • The card has been detected and recognised OOB
  • The bluetooth is working fine
  • The wifi chip has been detected but is acting strange:
    • The wifi card cannot detect any signal/list access points
    • Kernel_tasks process started to use CPU resources extensively (>80%)
I understood that the BCM94360CS2 (Apple brand) is supported fully without any use of specific kexts

I have attached my EFI just in case.

Thanks a lot in advance for your help :)

XhciPortLimit should be disabled after you have setup your usb ports
 
You might want to try adding AirportBrcmFixup.kext to your /EFI/OC/Kexts folder and config.plist, along with the following boot argument - brcmfx-driver=2 to force the AirPortBrcmNIC.kext to load.

As you are using Big Sur, you also need to specify MaxKernel 19.9.9 for AirPortBrcm4360_Injector.kext, to prevent this injector from working in Big Sur and newer.

Here is a link to download the kext and have a read of the information regarding use of this kext - https://github.com/acidanthera/AirportBrcmFixup
 
Guys,

I am so sorry and feel so stupid.o_O
I put back the old BCM43224
I replaced the old BCM43224 by the BCM94360CS2 again.
And....the Wifi is working perfectly :crazy:

Can't explain.

I would like to thank you so much Feartech and Edhawk for your swift reply and support.

Kind regards,

Yop
 
I just updated to 12.2.1 and have a a Dell 1560 card.

Is this the proper config for the card? I tries as shown below and with last 2 lines delete but still no WiFi or Bluetooth.

Using AirportBRCMFixup 2.1.4 and BRCMPatchRAM 2.6.2

I read the GitHub instruction but clear as mud.

The AirPortBrcm4360_Injector.kext stopped working in Big Sur. You need to remove or disable this kext when running macOS Big Sur or newer.
 
Have you tried using the BlueToolFixup.kext to fix your Bluetooth issues in Monterey - BlueToolFixup
