Hi @MaLd0n,
I have a hackffi with:
Mainboard: Asrock B450M pro4-f
CPU: AMD Ryzen 3500X
VGA: XFX HD 7730.
I use clover bootloader for Mojave 10.14.6 and it recogenize VGA with fakeID and injectATI (HD7730: 0x68371002 -> HD7750: 0x683F1002) full supported for everything. When i update from 10.14.6 to 10.15.2, i used OC and fakeid and injectATI with tutorial:
