My system worked fine up until updating to 10.14.4. I have my UHD 630 set to run headless and I use my Saphire RX 580 as my primary.

It now after going through the verbose output of boot goes to a black screen upon where it usually shows the apple logo. Any idea why this is happening? I think it is the headless setup doing it myself as my UHD 630 id 0x3E92 is supposed to be native in 10.14.4. But I have no idea what to do with that information.

Any help is appreciated.

Attached is my config.plist.

Have the same exact problem running the igpu headless and the rx580 running my primary displays. What SMBIOS are you running. I’m using 18,3

As mentioned by @Khaibit I am also having the same problem. Is anyone able to get a framebuffer dump on 10.14.4? I'm trying to check if something changed in hackintool but I can't get my system to dump the framebuffers. Edit: using -igfxdump boot arg with Lilu + WEG debug versions.

No dump output for me either -- could the KP before the OS boot completes be preventing this?

I think so unfortunately. I have been unable to get the system to boot with iGPU enabled even without injecting anything in device properties. I'm going to test older WEG versions.

I suppose I could always pull my RX560 and see if I can get a dump ... if I force the headless platform-id I imagine I won't get any actual video output but as long as the boot process completes... :lol:

As it turns out, in the documentation for WEG it indicates that if it detects a dedicated GPU and no platform-id is used it forces a 'headless' ID anyway, so chances are removing it from the Clover config didn't actually do anything for you.

Wow this is bad news i guess, without headless igpu there will be degradation in performance. luckily i'm still on 10.14.3
Keep us updated!
