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 ..

Yes. Everything working perfectly.

The problem is that after shutting down, one of these hardware (WIFI or BLUETOOTH) doesn't even appear in SystemReport anymore.

 

Fala MaLd0m, tranquilo?
Está tudo funcionando, o problema é depois que desliga.. alguma memória esta sendo perdida pq nem no SystemReport aparece um desses dois (Bluetooth ou WIFI).

Para voltar a funcionar os dois juntos, tenho que retirar e colocar de volta a placa da PCIe. Aí inicializa com os dois funcionando de boas.. muito estranho.

Já conferi e o Power Management está funcionando..

Sabe o que pode ser?

Thank you MaLd0n!

At the first boot I lost the WIFI. I took it out and put the board in PCIe back on and I'm going to do another series of tests ... but since then everything is working.

At boot appeared No schema for allowrelocationblock and blacklistappleupdate, I will update the OC to see if it resolves.


I'll send news
