ARGB headers not working after loading into macOS

Hey all! I have a strange behaviour with ARGB in my Hackintosh (RGB headers work fine).

  1. When I boot into Windows from my EFI, then shutdown, then boot again, ARGB work fine (configured from inside the BIOS).
  2. When I boot into macOS from my EFI, then reboot, ARGB work fine.
  3. When I boot into macOS from my EFI, then shut down, then boot again, ARGB leds are off.

I'm on ASRock Z790 Nova WiFi motherboard. In cases 1 and 2 Polychrome RGB works fine from BIOS, in case 3 I cannot access Polychrome RGB. In order to make ARGB work again, I have to switch the PSU off then back on and ARGB leds are working again (until my next powercyle inside macOS). Booting from the EFI into Windows does not produce that issue, and the problem affects only ARGB (3-pin) headers, not RGB (4-pin).

With my older EFI that problem did not occur, but my old EFI was badly configured and gave me a ton of problems. Now I was thinking that maybe I either could find someone who experienced the same issue and pin-point the root of the problem or get an ARGB controller that I could configure from Windows (since under macOS most - if not all - controllers are not working) so that the settings will be saved in the controller in order to work when I boot in macOS.

Thanks!
