Gigabyte Z390 M Gaming build with working NVRAM

[McMauro]

All your ports are active because you have the following enabled:

macOS has a 15 port limit. Although it's possible to circumvent it (like you have done), it's not advised. It can cause unexpected behavior such as breaking sleep/wake.

You do not need the following to enable headless IGPU. Delete the following the just let macOS auto detect it.

Uncheck the XhciPortLimit and delete your SSDT. The USB ports kext brings the total port count down to 15.

Pastry, with your OpenCore EFI everything works fine, though I have 2 issues.

1. The Energy Saver Preference Pane is not as it should be...

2. AppleALC ID 18 doesn't work for me through the green jack (HDMI/DP sound works though).
I've tried ID 1, 2, 3 and others (and it worked), but the sound volume is very weak compare to my previous Skylake build...

Thank you for your advices!

Did you change the SSDT-PLUG? Please try with the one attached below.

Where are you setting the audio-id? DeviceProperties or NVRAM? Have you tried clearing NVRAM?

I tried with the SSDT-PLUG from your EFI folder (14 064 bytes) and with the one I had from my Z170 (146 bytes only)... I will try with the attached one.

I set the audio-id both through Device Properties and through NVRAM (one at a time of course), and cleared NVRAM many times.

It works with the one you attached!

I don't know why it's not working for you. Those are the only ways I know how to set audio-id...

 

[pit512]

No problem pastrychef, layout-id 18 doesn’t work for me, but the others (1,2,3, etc.) work fine. It’s just that the volume is a bit low, but I can live with it...

One last question, don’t we need SSDT-EC on this build?

No.
