Concerning the bios, I think you only have to disable safe-boot. They aren't very configurable... To reach the High Sierra installer is kind of messy, since you have to disable the discrete graphics. There is a simple SSDT to do that though. The Intel wifi card will as far as I know never work...

I didn't think that's the problem either. It seems to be related to the screen. Why? Because I can boot when disabling the internal screen through the custom flag I wrote above. <key>framebuffer-con0-enable</key> <integer>1</integer> <key>framebuffer-con0-flags</key>...

I have tried many configurations. A setup with only FakeSMC, Lilu and WhateverGreen also result in it getting stuck at IOConsoleUsers... Patching the discrete graphics didn't help either. I guess I'll have to give up for now.

I appreciate that you took the time to have a look. I have read the guide many times. Are you referring to that I use WhateverGreen?

I have made some progress but can still not get it to work with WhateverGreen and Lilu. Through some device-properties entries I believe I'm finally pretty close... I can boot it with full nvram only if I add <key>framebuffer-con0-enable</key> <integer>1</integer>...

I have updated my profile with the chipset model and display resolution. For pr files, I used this script. Is there something more I should attach? https://www.tonymacx86.com/threads/tool-generate-proper-problem-reporting-files.235953/ Concerning the verbose photo, it flashes by so quickly I...

Yes, I can only get into the system with an invalid id, but even after rebuilding the cache the problem remains. Valid IDs 591b, (some people have suggested 5916, 5917) all give the same errors. So my question should have been what prevents the graphics from loading when I use the valid ID?

Borrowing this thread since I have a similar issue with the same card. I have been trying all the different invalid platform ids and fake-ids in this thread but can't get it to load the graphics kext... Would be very appreciated if someone could give a hint at which part (dvmt-prealloc, etc)...
