How to enable 'Kaby Lake' Intel 6xx Graphics (10.12.6+)

[meomap123]

Hi guys, i've setup an almost fully function hack with the specs: i7 8700k, Gigabyte RX580, MSI Z370 Pro Carbon, the only thing that does not work is the iGPU, Hardware encode is enabled but i encounter alot of video problem like youtube lagging and netflix showing only sound and green screen like the pic below:

Here's is the info of my system, config.plist and kext folder, all kexts is the latest update, i'm a total noob btw, please help, thanks.

Hi to all, i got random flickering problem on my Hackintosh, the only solution is to reboot, sometimes happen very often sometimes not, i attached my debug i hope someone could help me?
My monitor is connected thru DVI connector.
I think everything is ok in my config...
Could be a Intelgraphicsfixup bug? Could i use this kext patch instead?:

               <data>wOma</data>
           </dict>

P.S.
I got this problem from the upgrade to High Sierra, no problem with Sierra.

I have the exact same problem with my Hackintosh. Monitor is connected thru HDMI.

Motherboard: Gigabyte GA-H270N-WIFI
CPU: Intel I5 7600
Memory: 16GB DDR4 2400
SSD: Samsung 960 NVMe (PCIe)
WiFi: Apple PCIe Card WiFi
Bootloader: Clover v.4411


Sometimes, it works without any glitches all day long. But after a reboot or if I shut down and start again I have this flickering and the only way to fix is restart. Then I get the flickers again until after several restarts it stabilises.

You forgot to rename HECI->IMEI. It is required. Easily done with config.plist/ACPI/DSDT/Patches.

@RehabMan
Could you give a look to my debug if you can, just to have another couple of eyes, maybe i forgot or did something wrong, actually i can't see anything wrong but the problem is still there. Post #423

Yep. I just found it a few minutes ago. Now it looks like it is very stable.

Thanks RehabMan!

I think you're patching connector @1 (the 0204 port) as eDP <04 00 00 00>. You might try HDMI instead <00 08 00 00>.

<04 00 00 00> i thought was DVI-D

    "02000000" => "LVDS",
    "04000000" => "DDVI",
    "08000000" => "SVIDEO",
    "10000000" => "VGA",
    "00020000" => "SDVI",
    "00040000" => "DP",
    "00080000" => "HDMI"

I tried before <00 02 00 00> but not <00 08 00 00>, i'll try, and i'll let you know thanks.
Anyway it started with High Sierra, tested also different Smbios... actually it's a mistery

I really have no idea what connector-type DVI is... (I have no hardware with DVI, so no reason to look into it).
But I've heard of others just patching for HDMI for DVI ports (again, no idea if that is correct).
Macs tend to not have DVI ports!
But I've heard of those in the laptop space using <04 00 00 00> for eDP (again, no idea if that is correct... I have no laptops using eDP).
