    Hi I have a Acceleration on High Sierra and QuickSync
    1. Install High Sierra and
    2. Install Clover or update to the last version and with Multibeast 9.2.1 use the HD 530 patch, iMac 14,2 or 17,1 Definition (and others patch for your system)
    3.Install on /System/Library/Extensions (maybe works in EFI partition EFI/CLOVER/kexts/10.13) the next Kexts:
    upload_2017-9-30_13-1-27.png upload_2017-9-30_13-6-21.png
    4. With the EFI partition mounted, edit your config.plist with Clover Configuration and use the nexts patches in the pictures:

    5. Restart the system and you must have Full Graphics Acceleration and for the sound use de Toleda's ''audio_cloverALC-130_v0.3'' patch (and HDMI patch).

    I hope you help!

    You must use ''-shikivga'' bootflag too. Good luck!

    What are the highlighted FakePCIID used for?

    Hasn't this changed to -shikigva=1 in the new version?

    FakePCIID usually used for not native compatible hardware (for HD 530 is not necessary)

    Yes, shikigva=1 in the new version. My mistake, sorry! :p

    I now have High Sierra installed with graphics acceleration and HDMI Audio.

    I put all my kexts in /EFI/CLOVER/kexts/Other/ only (not in L/E and not in S/L/E)

    FakeSMC.kext
    IntelGraphicsFixup.kext
    IntelMausiEthernet.kext
    Lilu.kext
    BrcmFirmwareRepo.kext
    BrcmPatchRAM2.kext
    FakePCIID_Broadcom_WiFi.kext
    FakePCIID.kext
    shiki.kext
    USBInjectAll.kext <----- had to delete this though coz it was causing the system to be stuck at apple logo during boot up

    1. Added boot argument -shikigva=1
    2. I then disabled SIP and applied Toleda's audio_cloverALC-130_v0.3 and rebooted
    3. applied audio_cloverHDMI-130_v0.5 and rebooted
    4. ticked Rename HDAS to HDEF to disable
    5. added 3 AppleIntelSKLGraphicsFramebuffer patches into config.plist > Kernel and Kext Patches
    • HD530 Port 5 HDMI fix
    • HD530 Port 6 HDMI fix
    • HD530 Port 7 DVI fix

    I didn't need to apply the below patches though. usually I would test if I have the video acceleration after every reboot so I would know which part broke it. lol

    I didn't need to add the below though. but thanks for confirming this is possible!

    yeah I always download the latest. i figured it out, I had to put my SSDT-USB-H170N-WIFI.aml in EFI/CLOVER/ACPI , installed the kext again and no more problems. although I guess I could have just continued not having it as I seem to have no problems also.

    Hey everyone !
    I successfully updated to High Sierra using this guide
    https://www.tonymacx86.com/threads/update-directly-to-macos-high-sierra.232707/

    Follow all steps in the above guide carefully.


    I now have perfectly working HW Acceleration and everything is working fine except Audio ALC 1150 (please help me if you know the fix), which I'm figuring out.

    Plus, I updated my SSD to APFS in the process.

    To get acceleration please update Lilu.kext, Shiki.kext, HiberationFixup (if required) and IntelGraphicsFixup.kext to latest. Install these with KextBeast before performing HS update.

    If you have enabled TRIM on your SSD then you might experience slower boot times due to a still unknown issue. Therefore disable TRIM for the time being and boot times will be normal as before.

    If anyone needs any help I'll be happy to do so.

    Thanks
