I changed the system definitions to iMac18.2 (no IntelGFX fakeid, set ig-platform to IntelHD630),

IntelHD 630 is recognized by the system

VDAcheck fails,

MacX shows no acceleration,

h264/h265 4k videos wont use the IG, nor are videos on youtube/Photos.app.

Attaching my updated config + EFI folder.

See post #30 from this thread. You need to use a connector less ig-platform id. Igpu will not show up in about this mac when properly configured and VDA checker will confirm once correct platform id is used.

I use the proper connectionless platform id already, inject intel etc., but I still dont have quicksync.

Attaching my config.plist, CLOVER folder with kexts I use, IOREG etc. Please, let me know what you think I should change or try, thanks.

In clover config/system parameters make sure you check inject system ID. Try VDAChecker again. Looks like IGPU properly configured.

If it doesn't work with proper system id injected you may also want to try to reset your DRM as described here https://github.com/vit9696/Shiki/blob/master/Manual/FAQ.en.md

Then try VDA checker again.

YOU SIR! YOU ARE A GENIUS! Thank you so much, I've been looking for solutions to these problems for some time and no-one has suggested this simple trick.

Well, now, I have VDAcheck passing "Hardware acceleration is fully supported"

(but I get and error: "/BuildRoot/Library/Caches/com.apple.xbs/Sources/AppleGVA/AppleGVA-11.3.7/Sources/Slices/Driver/AVD_loader.cpp: failed to get a service for display")

macX reports Intel acceleration!

Quicktime uses the IntelHD when playing h264/h265 content!

THANK YOU!

it takes 40 secs to export. idk if thats a good export time.
It's decent for an NVIDIA setup (AMD GPU get render time under 10 seconds) and shows that there is definitely something wrong with my setup since I've got higher specs... Hmm something else to sort out and fix! :)

Shikigva=12 works,
IntelGraphicsFixup.kext, FakePCIID_Intel_HD_Graphics.kext are not necessary for my Kabylake CPU
