Finally, I managed to run BT and WIFI on this card with the BIG SUR on H370M. Its easy:

• Update all opencore folder with lasts files
• kexts in this order:
AirportBrcmFixup.kext - enabled
AirportBrcmFixup.kext/Contents/PlugIns/AirPortBrcm4360_Injector.kext - DISABLED
AirportBrcmFixup.kext/Contents/PlugIns/AirPortBrcmNIC_Injector.kext
BrcmBluetoothInjector.kext
BrcmFirmwareData.kext
BrcmPatchRAM3.kext
• Done

Everything working perfectly, I restarted several times to test and everything was wonderful, until: shutting down.

After turning off the computer and waiting for some time (I don't know if any information is stored for a few seconds, maybe PowerManagement?) and when I boot again I only have either BT or WIFI. One of these hardware doesn't even appear in SystemReport anymore.

I only managed to get both to work again (Believe me) by removing the PCIe card and putting it back. Until the shutdown BT and WIFI work like a charm.


I did a sequence with more than 20 tests.

1 Hardware DowUp (removing the PCIe card and putting it back)
boot 1 OK
boot 2 BT ERROR
boot 3 BT ERROR
2 Hardware (removing the PCIe card and putting it back)
boot 1 ok
boot 2 ok
boot 3 ok
boot 4 ok
boot 5 - fast shutdown and turn on immediately ok
boot 6 ok
boot 7 ok
boot 8 - shutdown and wait 30 seconds BT ERROR
boot 9 - BT ERROR
boot 10 - BT ERROR
2 Hardware (removing the PCIe card and putting it back)
boot 1 ok
boot 2 BTok WIFIerror
boot 3 BTok WIFIerror
boot 3 USB2 BTok WIFIerror
3 Hardware (removing the PCIe card and putting it back)
boot 1 ok
boot 2 BTok WIFIerror
boot 3 BTok WIFIerror
boot 3 BTok WIFIerro
4 Hardware (removing the PCIe card and putting it back)
boot 1 ok
...


Why does everything work when you remove and insert the PCIe card? What kind of memory is being lost?


It seems that my Power Management works well, correct?
Any suggestions please ..

If it is the same MOBO (H370M), try these kexts updated with opencore 0.6.4

Have you already tried to remove the PCIe card and insert again on MOBO?
