After boot without injecting intel *-platform-* mac os trying to boot, but after string :
IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0,
workstation continue to work when monitor is showing No Signal.
When I injected *-platform-* 0x59860000 I can boot, but video memory only 10mb.
I followed other guides for coffee lake, but no one was helpfull. Injecting 0x3E920007 also worked, but video memory still 10mb.
I have latest Lilu and Whatevergreen in kexts/Others/ folder.
For SMBIOS I used iMac18,3 iMac18,1 Macmini8,1.
I think this must be related to z390 motherboard but not sure.
Monitor connected by HDMI.

Trying this https://www.tonymacx86.com/threads/...3p-uhd-graphics-630-macos-high-sierra.239402/ reference, but no result.

Having trouble with my MSI Z390 A Pro 8700k as well.

VGA works fine but my DVI gets no signal after ~80% on the Apple boot screen.

Did you find a solution for this yet?
