Just to confirm, trick from the first post is working for me (at least it seems for now like everything is ok, I didn't experience any bugs, hangs or any problem at all).
Installation of High Sierra on my configuration has passed almost without any intervention except some drivers from Multibeast.
It seems that last version of High Sierra recognizes RX480 OOB so I didn't use Whatevergreen and Lilu kexts and have disabled IGPU in BIOS and let system works only with RX480.
So I started Clover Configurator, load my config.plist and choose iMac 14,2 (I think it could also work with 18,3) in SM BIOS section, than simply replace text in appropriate boxes whit this (without quotes):
SMB_BIOS_VERSION "IM191.88Z.0058.B00.1705091711"
SMB_PRODUCT_NAME "iMac19,1"
SMB_BOARD_PRODUCT "Mac-CF21D135A7D34AA6"
And got FCPX to export h264 normally.
It is not nearly fast as it was in Sierra with same configuration (and with Whatevergreen and Lilu kexts), but it is much better than before this trick from post #1.
In Sierra I got video of 5.5hours to be exported in 45 min, and now I got 2 hours of video on timeline to be exported in 3 hours. Or 60 sec of 1080p video for 90 sec exported, it is a ratio of 1.5x.
Before this trick and with integrated graphic turned on it take 5-6 hours for same amount of video on timeline.
So it was better/faster in Sierra than now in High Sierra, but it seems like FCPX don't fully use GPU for some reason.
I had idea to change GPU to RX580 because it is natively supported in High Sierra, maybe FCPX would use it as it is intended and that would get back speed from Sierra.
Bruce test in Sierra was 30 sec and now in High Sierra it is 35 sec if it is relevant.
Just to be clear, you are using this setup with an RX580 and the iGPU disabled? Is it still working? I'm having the same issue with my Hackintosh build using an i7 8700K and an RX580. This is my first Hackintosh build (just completed this morning) and I cannot export H.264 from Final Cut without enabling the iGPU, which leaves the RX580 doing nothing and the export itself runs as slow as molasses.
Any help would be greatly appreciated.
