ZikPhil Posted June 21, 2018 Share Posted June 21, 2018 (edited) My specifications are as follows: iMac 18,1 (iMacPro goes black screen after boot) GIGABYTE Z370 AORUS Gaming 7 / Intel Core i5-8600K Coffee Lake 6-Core 3.6 GHz / 32GB Corsair Vengeance DDR3 @ 3000MHz Sapphire AMD Radeon RX 580 8GB (Collected from External Graphics Kit from Apple) 200GB NVME Drive (Samsung) + 500GB Samsung 2.5" SSD Big thanks to @MaLd0n to help me get as far as I did by providing me with DSDT and Clover config for High Sierra Installation Procedure: Upgrade from Mac App Store after installing the profile from the Apple developer site. Upgraded to Beta 2 the same way. What does work: Graphic Acceleration iMessage USB ports are all working Thunderbolt 3 (with TB-BRIDGE Add-on card, no hot-plug) Shutdown Restart Audio (through Thunderbolt 3 Dock, on-board audio is not working but I think it's just a matter of updating the kext) Ethernet What does NOT work: Sleep and Wake (more on that below) Sleep/Wake & General Graphic Issues I am having on and off issues with my graphic card. Sometimes it will just freeze, my mouse keeps moving, audio works but both screens are completely frozen. A hard reboot fixes that. And then just overall when I have to go through the login screen, whether it is on wake or on normal boot, both my screens just turn black. I get 1 screen that goes "no signal" for a few minutes and then comes back up black. If I wait 2 minutes while pressing "Enter" every once in a while, both screen flickers and eventually my login screen shows up. This is very weird. I have internal graphics enabled in my BIOS but I don't see it in System Information, I would be willing to do whatever it takes to fix it even if it means disabling internal graphics. Any help would be appreciated. Also worth noting I had issues with my GPU on High Sierra too. Thanks!

ZikPhil Posted June 22, 2018 Author Share Posted June 22, 2018 (edited) Fun fact, "Internal Graphics" was Disabled in my BIOS. Not sure what happened. When I enable it + Your CLOVER: Clover is throwing a "unable to allocate runtime area" error When I enable it + my previous config.plist: Clover is throwing a "unable to allocate runtime area" error When I disable it + Your CLOVER: It boots but I get black screens after. I had to restore my previous clover folder for things to work. Also (random fact) on reboot sometimes I get this: https://imgur.com/a/X7vG5pt Here are my BIOS config while I have internal Graphics enabled: https://ibb.co/gkcmH8https://ibb.co/jEZ0c8 Edited June 22, 2018 by ZikPhil Link to comment Share on other sites More sharing options...

Gigamaxx Posted June 22, 2018 Share Posted June 22, 2018 I had a similar issue With my RX 480 and RX 460 cards in Mojave. I would get black screen after boot but could see the cursor and flickering. I connected my monitor HDMI to a Displayport to HDMI adapter and now they both work. So it seems the HDMI ports were/are the issue for me. Link to comment Share on other sites More sharing options...

ZikPhil Posted June 22, 2018 Author Share Posted June 22, 2018 I tried disabling and removing my TB3 card, that still didn't fix the Clover error when activating Internal Graphics. Link to comment Share on other sites More sharing options...

ZikPhil Posted July 21, 2018 Author Share Posted July 21, 2018 (edited) Hey @MaLd0n, I was finally able to boot using my IGPU + GPU by spoofing a kaby lake platform-id and disabling gfx firmware. Im sure it's not the right way but at least I got in to generate the RunMe. Here it is: https://www.dropbox.com/s/zmxk409nmezxut6/Send me Prometheus.zip?dl=0 Thank you <3 Edited July 21, 2018 by ZikPhil changed link for permanent one.

ZikPhil Posted July 21, 2018 Author Share Posted July 21, 2018 Ok so I had to take out the DSDT.aml that I had previous because it was causing boot errors very early on in the process. This is my current config including fresh DSDT drop. Both IGPU and my RX580 are recognized, 1 screen connected in each, both working. @MaLd0n If you could look at that and generate new DSDT it would be perfect.
