Issues

USB

This board usb device id is 0xa3af which is not supported by default in USBInjectAll.kext and XHCI-unsupported.kext, hence rename is required in both kext 0xa2af > 0xa3af.

Color banding

I came across this issue with this build even though I didn’t get this issue with my previous build using the same monitor. Solution: EDID injection using Hackintool via kext Display-10ac-d0d7.kext + SwitchResX app, change setting from Billions of colors to Millions of colors

BIOS POSTed in safe mode

As explained here, the solution to use the boot-arg rtcfx_exclude=00-FF
