LOL
I am on 10.14.5 ✅
disabled IGPU ✅
iMacPro1,1✅

H.264 hardware exc. ❌
HEVC hardware exc. ✅
Do not inject intel or define an ig-platform-id. Just use WEG and lilu. I don't know if the RX570 will play nice with the iMac Pro 1,1 SMBIOS. Why dont you use iMac 14,2? Also remove the shikigva flag and radeondelnit. Do you make much use of HEVC?
I think the people changing to the iMac Pro SMBIOS are people with the Vega GPU
 
  1. Copy and replace EFI folder
  2. Disable IGPU from BIOS
  3. If you will see a black screen, remove the boot args -wegoff at the clover boot screen.
  4. :think:

Help is needed! When adding any effects, FCPX hangs. Sometimes freezes and no effect during work. Just the picture freezes, the sound can go and the mouse move, but the computer does not react to anything. I deleted the dummy, updated lilu and weg. The coding and everything else works well, but because of the hang it is not possible to work with effects and difficult installation. OS 10.14.6 (18G29g)
 
I don’t have freezing in FCPX, maybe because I am injecting the framebuffer Orinoco, 33W at idle.
It freezes me! How do you do it? Can you give me your efi folder?

it is better to show your hardware in your profile, without knowing the hardware, there is no way to help

I am facing same issue. Tried many things but it hangs still. Reverted to 18,3 with iGPU enabled.
