Looks like a sweet build. Thanks for the clear steps too. Am trying to conquer graphics with H370 version of that board. Following your steps end me in black screen on boot though there should be no need to fake id with an 8400?
Also any reason why you went with Mac Mini 8.1 over the iMac 18.1 SMBIOS? Thanks.
After every reboot and black screen - boot from UniBeast drive, select your HDD as dthe boot device in Cover. Boot into system with 7MB VRAM. Restore config.plist to condition before patches. Reboot. Open hackintool framebuffer patch guide add go step by step one more time.
(I use 0x05 bus ID for HDMI, and by the guide it should'nt work, but it does. It was my guess, so try as much as you can and all gonna be done.)
No fake ID for UHD 630 with the i5-8400, but whatevergreen+lilu+"inject intel" in Cover.
Before hackintool patches, I had full accelerated video, but no hotswap HDMI.
After patches, I got 2048MB VRAM instead of 1536, and both HDMI's hotswap and simultaneous work.
Why macmini8,1?
First - my build looks more like a Mac Mini than iMac
Second - all we know sometimes setting correct SMBIOS can add more compatibility.
As long as MacMini8,1 useS UHD 630, I think it is a good idea.
