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
Hi, I tried during last 4 days almost everything but now I call for help. I have RX560 running on 10.13.4. Previously I was running it on 10.12.6 and had the same problem, but after waking from sleep my thiord display came to life, but it is not working anymore on 10.13.4. Without or with Lilu & Whatewergreen my system correctly recognize my gpu as RX560 but only 2 of 3 displays are displaying content, third display is black but recieving some signal. When I change cabling and connect only two, any combination of 2 displays is working. System profiller and system preferences are sayin I have 3 displays connected.
Please can somebody help me to figure it out? Thanks a lot in advance. Tried to upload my ioreg but it is greater than 10MB allowed for me :(
Hi, i recently set up High Sierra on my AMD computer with the help of the amdosx community (i actually used an installer just to confirm that something would work in the first place before i spend hours for nothing, i can and could have downloaded High Sierra the "legal" way).
However the graphicscard is recognized properly, the 6gig are recognized and i have no artifacts and no screen tearing with the official nvidia webdriver,
but unfortunally, dark colors have horizontal dark stripes in them and specific bright colors like on left bar of system windows such as settings do flicker like low fps.
I only used the clover on the flash drive for now and i'd like if it's worth digging deeper of if i should just forget about it as it is a common nvidia problem on macOS.
Would be amazing to know.
Closer machine infos:
* High Sierra (misses a recent minor patch as my network is veeeery slow and i got this nvidia issue anyway so i mainly jumped back to linux)
* AMD fx8350
* Asus Sabertooth 990fx Ref. 2.0
* NVIDIA GeForce GTX 1060 6GB
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?
