I have the same problem as the OP: I followed the guide for direct update from Sierra; it starts verbose booting all right, but when the High Sierra (10.13.1) OS installer GUI is supposed to load I get a black screen
Hardware: GA-Z87X-OC Force - Radeon R9 280X - Core i7-4770K
Clover 4818 - kexts/Other: FakeSMC.kext, Lilu.kext, WhateverGreen.kext
Two monitors are plugged into two DVI ports
Graphics and everything (incl. sleep) work fine in Sierra 10.12.6
I additionally tried the suggestion from elsewhere, that AMD cards in High Sierra need driver rollback from Sierra. I included the following 10.12.6 kexts in a modified BaseSystem.dmg in 'macOS Install Data':
But the system crashed with a KP.
- AMD7000Controller.kext
- AMDFramebuffer.kext
- AMDRadeonX4000.kext
- AMDSupport.kext
- IOAcceleratorFamily2.kext
Has anyone found another solution which does not require the fancy framebuffer editing described by carpentryplus25? I do not think I could figure out the framebuffer, like he did.
Update clover to latest and add RadeonDeInit=true to you config.plist like so
Code:
<key>Graphics</key>
<dict>
<key>FBName</key>
<string>Namako</string>
<key>Inject</key>
<dict>
<key>ATI</key>
<true/>
<key>Intel</key>
<true/>
<key>NVidia</key>
<false/>
</dict>
<key>NvidiaSingle</key>
<false/>
<key>RadeonDeInit</key>
<true/>
<key>ig-platform-id</key>
<string>0x0d220003</string>
</dict>
Then if that doesn't work try my framebuffer patching guide described here
