How to make AppleHDAController load on Ryzen boards?
Rename(/add) your audio controller to your DSDT/SSDT as HDEF
Add a _DSM method to your HDEF device with layout id 1
Patch the AppleHDAController binary, because it has a static table containing the supported PCI Vendor/DeviceID pairs and it also checks the VendorID against known values. As an example I provide a dif file and patched 10.13.3 binary, but if you want to I can patch the binary for other versions.
After AppleHDAController loads to actually get sound working you need to patch AppleHDA.kext for the codec on your board. First I tried to use Lilu+AppleALC for this task, but for some reason it refused to work. (I might look into it later why) But for the time being it was easier to use toleda's cloverALC script for that, but to make it work I had to change(/remove) the specified location of the HDEF device from the script. And for some reason it also required me to mount the EFI partition manually.
if [[ $(cat /tmp/HDEF.txt | grep -c "HDEF@1") != 0 ]]; then
if [[ $(cat /tmp/HDEF.txt | grep -c "HDEF") != 0 ]]; then
Please help me with this 10.9.5 system. Motherboard: Gigabyte 965p-s3 rev3.3, gpu: Ati Radeon HD6450 (dvi/hdmi/vga).
Using any of the 3 ports on the 6450 (dvi, hdmi, vga), I see all the white letters on black background during boot but when they complete and it's time for the graphics to start I get a black screen and sometimes a restart after that. Using Clover 4411. Is there any way to get past this?
Could you please help me enable the VGA port on the GT710 in 10.9.5 13F34 ?
It is currently booting fine through its HDMI port, web driver 334.0103f01 and config.plist arguments checked: Verbose (-v), npci=0x2000, dart=0, nvda_drv=1
The nvidia GT710 works fine through its VGA port and web drivers on a friend's Mac Pro 3,1
I must soon return this borrowed HDMI monitor, mine only has a VGA port so I'd appreciate your input.
