iGPU for i9-9900K - no HDMI output

[CaseySJ]

Im trying, but Im getting no acceleration :/ Please check my config from picture if I used these values correctly

That doesn't look quite right -- you still have device-id 3E98, which is not recognized by MacOS. Try removing that line and adding framebuffer-patch-enable --> 0x01000000.

Or try it a different way, without the use of "Device --> Properties", as shown in the 2 attached screenshots. Be careful to note all the values and checkmarks. GPU ID is entered in image 1. ig-platform-id and "InjectIntel" is entered in image 2.

Didn't work :/ Here's my EFI - now system reboots while loading, when it supposed to show desktop

Notice he said "I also had to use iMac17,1". The SMBIOS section of your config.plist has iMac18,1. And he used ig-platform-id 0x59120000, but your file has 0x59120003. Again, no guarantees this will work since I haven't tried it myself.

Hi,

The problem is SOLVED.
Ik have found another post where as the would recommend the following:
IntelGFX: 0x59128086
ig-platform-id: 0x59120000
Inject Intel.
Install Lilu.kext and Whatevergreen.kext to /Library/Extensions with KextBeast.

I also had to use iMac17,1, when I use 18,3 the image flikkers.


It seems to be working for now.

Thats right, I tried with iMac17,1 too. Changing to 0x59120000 is also not helping, still no acceleration

Ouch, I was really hoping for a solution as well. You can see my experience with this here. Scroll to:

Status: Internal Graphics UHD 630.

Eventually I plugged in an AMD Radeon RX580 and it's working really well. In fact you cannot get 4K60 from the Intel UHD 630, but that's no problem for the RX580. So another reason to get a discrete graphics card...
