    Doesn't need to add any bootarg, just to copy the Shiki.kext to /EFI/CLOVER/kext/Other (among Lilu).

    NOTE: Shiki is to help us to activate the DRM playback. Also you can use the bootarg shikigva=1 to "enable Intel online video decoder when AppleGVA enforces offline", which disables the GVA through the discrete GPU (I guess). On my case, the shikigva=1 disables VDA and iTunes stop crashing.

    @elmacci I've testing right now this configuration:
    - All the newest compiled kexts.
    - Updated the value of id-platform-id on my clover config.plist, to a most accurate with my CPU model (Haswell, from 0x04120004 to 0x0d220003).
    - Using the shikigva=1 bootarg
    - The latest high sierra (17A405)

    Results:
    - iTunes doesn't crash (at least for the six hours)
    - H/W acceleration ON

    Code (Text):
    $ ./VDADecoderChecker
    Hardware acceleration is fully supported

    My iTunes only crashes first time I load it and when I close it? Only with the shiki = 1 bootflag.

    I've double tested this theory - it's completely repeatable on this machine.

    There are two new bootargs that you can use for Skylake or newer processors.
    According the Shiki's readme:
    There are a new one "shikigva=12": temporary process whitelist for 10.13 SKL/KBL & NVIDIA (`shikigva=12`)

    PS: use the kext that I've attached in the post #134

    Cheers

    I’m using HD530. I think I’m using the correct boot flag? I tried 4 which made an instant kernal panic.

    Wow :(

    See the post from @tonymacx86 - maybe it helps.
    At the moment, I'm ok with the configuration that I've shared before.

    PS: could you attach your config.plist file? Or, have you configured correctly the ig-platform-id?

    Did this fix your problem? What is the solution for Haswell and iGPU?
