Hello!
I had a working Sierra 10.12.6 Setup.
Mobo: GIGABYTE P61-USB3-B3 (H61 Intel 6 series Chipset, Cougar point, No IGPU, only discrete, Legacy BIOS)
CPU: i5-2300 2.8 GHz (Sandy Bridge)
GPU: MSI Radeon RX 580 8GB

Yesterday I tried to install Mojave but I can't get to the installation screen, I getting black screen after booting. I have 2 HDMI monitor, they have signal, just black.
- I think this problem is related to AppleGraphicsDevicePolicy, so I used iMac14,2 smbios instead of iMac12,2 -> nothing changed, same black screen.
- Used several AppleGraphicsDevicePolicy patch, nothing changed. And if I understand correctly I have to change the value to "none" in Info.plist, but I can't even get to the install screen, so I can't modify the Info.plist.
- Some users can get signal when using DP ports, but my monitors don't have DP connectors, just HDMI.
- Tried WhateverGreen + Lilu (same happens without them) and Inect ATI = true, RadeonDeInit = true (same without deinit)
- My motherboard doesn't have IGPU, so I can't enable that, i'm just on the discrete.
- Some users got to the installation screen by enabling CSM: my motherboard has Legacy BIOS (with Hybrid EFI technology) I don't have CSM option
- At Sierra it's good, my 2 monitor recognized correctly.
So maybe if I will able to edit that Info.plist I can finally have signal, I don't know. Appreciate any help.
UPDATE: I have signal with DP port (DP to HDMI), but no signal on HDMI ports...looking for solutions.

2nd problem is that my SATA drive doesn't appear in Disk Utility.
- At Sierra no problem
- High Sierra, no drives -> fixed by restoring AppleAHCIPort.kext v328 to S/L/E
- This problem maybe related to my chipset, because maybe that is not supported anymore (Intel 6 Series chipset, H61)
- At Mojave I tried to modify the BaseSystem.dmg in the Mojave Installer.app to restore AppleAHCIPort.kext v328 -> My drives got recognized but not initialized, also broke the partition and I have to reformat.
- Tried another AHCIInjectors, nothing changed.
- AHCI-SATA: Enabled in BIOS. -> Fix in #2 post
Attached my whole clover folder.
