I really did not do much special config. I installed these kexts in
EFI/CLOVER/kexts/other/
-FakePCIID.kext (this is the only kext I have here in my setup)
I put these in
/Library/Extensions/
- FakePCIID_Broadcom_WiFi.kext
- BrcmFirmwareData.kext
- BrcmPatchRAM2.kext
- BrcmNonPatchRAM2.kext
Now I am aware that placement of these kexts are very confusing since some say to put everything in
EFI/CLOVER/kexts/other/ (should be safer since you then have a chance of a safer boot from USB in case things go wrong and even Clover Config puts them there) and some write to put everything in
/Library/Extensions/. I have success with BT on unsupported cards with both placements. This is really confusing! I read this:
"Having issues?
Some may have issues putting these kexts in the Other folder where the Kexts wont always work or maybe Wifi is working, but bluetooth isn't. With Clover some kexts can fail to properly initiate so you can try migrating BrcmPatchRAM to /Library/Extensions:
Move BrcmPatchRAM2.kext & BrcmNonPatchRAM2.kext to /Library/Extensions
Delete BrcmFirewareData.kext from EFI/CLOVER/kexts/Other
Copy BrcmFirmwareRepo.kext from Release folder
Paste BrcmFirmwareRepo.kext in /Library/Extensions"
On my latest build I used a GB Aorus Z390-i WIFI ITX. I just sold it because of the CNVi card. A few days ago, I got a ASRock Z390 Phantom Gaming-ITX/ac. This had the same CNVi card like the Aorus Z390. I replaced it with a Dell DW1560. I was so glad that this worked out of the box. Both WIFI ac and BT 4! I was a little worried since the notch was the same but the pins were very different. I know the CNVi card is super fast with BT 5. It works fantastic in Windows. So, it is a shame there is no solution for macOS. I have not tested but read that also the ASUS Z390 ITX has this card but can also accept M.2 cards. The Aorus is locked to the CNVi format which Gigabyte support confirmed for me.
I have very good experience with Gigabyte mobos and like the BIOS setup. The ASUS boards are even better I think but often much more expensive. I definitely avoid MSI and always experience more fuss with ASRock but the Phantom seems to be a good mobo. I just never get to like the BIOS setup, a little confusing I think, specially the overclock setups. The GB and ASUS mobos I found easier to understand. Just my opinion though.
Sorry, I got carried away with this long post but hope you got some help
