Well, the workaround from Shiki works fine - thanks a lot @vit9696!
One issue, maybe is my configuration, the video playback for purchased movies is black, only audio.

You need to download the latest sources and compile it.

Please see my attachment (these are the kexts that I'm using).

Yes result... I have hardware acceleration by modifying the /System/Library/PrivateFrameworks/AppleGVA.framework/info.plist

And using intelfixup, lilu and the newest shiki with bootflags shikigva=1 and shiki=14 iTunes is stable! I can watch trailers with no issue streaming of full films has black screen as mentioned but downloaded content plays perfectly. I'm not sure if I should be using both bootflags... ?

Thanks for sharing, everything seems to be ok, but something weird, AppleSNBFBUserClient no longer load while iTunes is running.

Previous post, replacing 10.12.6 CoreKE.framework also work, indeed I have tested several days without any iTunes issues, result similar to new shikigva=16, from ioreg reading, both disabled HW DRM check from iTunes startup, but I don't know the different.

bootflags shikigva=1

If you edited forceOfflineRenderer = No in AppleGVA info.plist, do not need shikigva=1, same result as forceOfflineRenderer = No.

If you want to disable HW DRM (KILLGVA by shiki) then use shikigva=16.

I seem to have acceleration and AppleSNBFBUserClient loaded... No idea what that means though!

When iTunes is running, in 10.13.x normally AppleSNBFBUserClient should loaded no matter in HW DRM or SW DRM mode.

If SW DRM mode is on, only AppleSNBFBUserClient is loaded and show iTunes thread number.
If HW DRM mode is on then AppleSNBFBUserClient, IGAccelVideoContextMedia, IGAccelVideoContextMain, and IGAccelVideoContextVEBox should loaded and show iTunes thread number.

Therefore when using shikigva=16, ioreg reading is weird, none of them show up while iTunes Music is playing.

I'm not sure whats wrong but the new Shiki has not resolved my crashes, am I fighting two issues?

VDADecoderChecker: HW Acceleration is fully supported
