From what I can tell you'll need this, https://github.com/RehabMan/OS-X-BrcmPatchRAM

Check your device ID under supported devices, https://github.com/RehabMan/OS-X-BrcmPatchRAM#supported-devices

quick question I am not finding a kext called BrcmPatchRAM but I do see a folder named that in the zipfile. where would the kext be? I found the firmware kext

cant seem to get it working. Air Drop lets me turn it on but thats it. No bluetooth. Could you recommend a more compatible usb bluetooth adapter?

Well I went to Best Buy and got the Insignia one and nothing!

Inject BrcmPatchRAM2.kext and BrcmFirmwareData.kext with OpenCore and it should fix it.

I’m not sure why it’s not working for him unless it’s just not compatible.
@Graystarr i have a GMYLE Bluetooth 4.0 usb dongle sitting here and just plugged it in and that works fine with nothing doing to it.
Just checked and you can pick one up from Amazon US for ten dollars. That might be the best thing to do if the other two are both no goes.

@Graystarr I just checked your Config.plist and your using BrcmPatchRAM2.kext when you should be using BrcmPatchRAM3.kext for Big Sur.
Try your Config again with the correct kexts added.
BrcmPatchRAM3.kext, BrcmFirmwareData.kext & BrcmBluetoothInjector.kext

I think I must be doing something wrong as I am not seeing these kexts being loaded. Would ya mind walking me thru the steps please?

Post your EFI minus your SMBios details and I will amend it for you.
