    ForceCompatibleRenderer = 4,
    Accrodig to kern_shiki.hpp, shikigva=32 is for replacing board-id. So I would suggest you using the command below.
    Code:
    sudo nvram boot-args="shikigva=32 shiki-id=Mac-7BA5B2D9E42DDD94"
    For detailed information, please check

    These patches are for hakintosh smbios not the cMP smbios. I don't believe there are such NVRAM variables in the real Mac firmware.

    These are boot arguments and they certainly work for real Macs. At boot time, the WhateverGreen plugin reads these parameters and acts accordingly.

    This is what I was thinking.
    Thanks for the info. In that case, we may start with 32, then see if 1,4,8 make any difference (if pure 32 doesn't work).

    I may be wrong, but there are places in the firmware NVRAM where an user can write and some sections/places where the user cannot write. I would imagine the board ID is the latter case. Is that correct @tsialex?

    board-id is not set by the NVRAM, it's set by an EFI module. The idea here is to bypass it.

    Add a note here, it's 10.14.5 beta 4 (18F127a).

    @h9826790 Kina pleased by the result. Could you maybe also try using the command below to see if board-id has been changed?
    Code:
    ioreg -lp IOService | grep board-id

    Great news!
    So to conclude the board Id does not matter. You only have LILU and Whatevergreen and the original AppleGVA.framework right?

    Great! Could you also add it to the:
    https://forums.macrumors.com/thread...-5-1-upgrade-guide-sticky-discussion.2099092/

    What is sad is that Apple decided to block this feature in Mojave. And I don't see the reason for that as it is enabled in Windows and you can use Windows on the cMP.

    Unfortunately, Netflix on Safari is still a no-go.

    I can confirm this also works with Vega Cards.

    Tested with RX Vega 64 and Radeon VII sadly those X5690 bottleneck in SingeCore Performance but I will not try it on my main rig until 10.14.5 is final.....

    Also DRM Content Playback does NOT!! work (If you need that I don't use it)

    Has anyone tried this same method with the publicly available 10.14.4 18E226, or will this ONLY work in 10.14.5 beta versions at the moment?

    This will only work 10.14.5, I don't even know if it works with the Public beta of 10.14.5

    Correct, I only get red screen and the sound when playing DRM content, no solution to get both hardware accel and DRM content playback at the same time yet.

    However, it's relatively simple to temporarily disable hardware accel by clearing the boot argument, and reboot. Then the user can enjoy the movie. After than, set the boot argument again as per step 14, and reboot again to get hardware accel back. With SSD, 2 reboots only cost a min, not too bad IMO.

    True, after all I use an ATV 4K anyway for iTunes... AND Netflix works with 1080p in Chrome (I think even with Hardware accel)
