rioredstone Posted November 13, 2017 Share Posted November 13, 2017 I've been trying to have my RX460 work. in vanilla state, it worked only in safe mode. I found some kexts, AMD95**, which have the same device id as my rx460, 0x67EF1002. so I removed 9510, 9515 and 9520, then it works without no acceleration. so I compared High Sierra's AMD9500 with Sierra's. High Sierra's AMD9500 contains "AtiGpuWrangler" in IOKitPersonalities. and the os loads AMD9500ControllerWrangler, and does not load AMDRadeonX4*** framebuffer. on Sierra, AMDRadeonX4200 is loaded. I think, in order to have my RX460 work, AMDRadeonX4*** need to be loaded. so now I have a question. what is AtiGpuWrangler? what is AMD9500ControllerWrangler? and also, in IOKitPersonalities in AMD9500, there are 2 IOMatchCategory, IOFramebuffer in AtiGpuWrangler and ATIFramebuffer in Controller. what does this means??

nvflash Posted November 17, 2017 Share Posted November 17, 2017 May not be your problem, but I had to turn off CSM in my UEFI to get my RX580 working. Link to comment Share on other sites More sharing options...
rioredstone Posted November 18, 2017 Author Share Posted November 18, 2017 @nvflash sadly, my machine has Legacy BIOS. but RX460's bios has a legacy part and a uefi part, hybrid bios. Link to comment Share on other sites More sharing options...
blitz9826 Posted November 18, 2017 Share Posted November 18, 2017 hola! i'm running a kaby lake machine, uefi only, with PEG (graphics card) as primary; asus mobo with 270 chipset. anyway, i have the same issue, and the same card worked oob with 10.12 (although i had to keep iGPU enabled, but that combination won't work here). any help? maybe a hotpatch?

rioredstone Posted November 21, 2017 Author Share Posted November 21, 2017 @bbmatias3 lilu and whatevergreen don't work on High Sierra in my case. I use Mieze's method, http://www.insanelymac.com/forum/topic/328549-tracing-back-the-amd-gpu-wakeup-issue-to-its-origin/. I wrote the lines on DSDT. on Sierra, my rx460 works well as oob without a helper or additional kexts. but, on High Sierra it doesn't work, with lilu and whatevergreen, a black screen occurs, no graphics comes.

inequals Posted November 25, 2017 Share Posted November 25, 2017 Hey, I'm using HS with a 460 (as in my sig). Everything works, only issue I have is after waking from sleep video acceleration doesn't work. However, you should be able to get more than a black screen! How is your display connected to your hackintosh, and have you tried different ports? E.g. if it's connected via HDMI try DisplayPort or DVI.

How is your display connected to your hackintosh, and have you tried different ports? E.g. if it's connected via HDMI try DisplayPort or DVI. @inequals I think missing devices after waking after sleep can be caused by DSDT or SSDT. how's your DSDT?? In my case, all port, DVI, DisplayPort, HDMI can't catch a signal. which framebuffer does your High Sierra use?? Bro Same issue on my AMD radeon HD 7650M, no QE/CI. Its working grt on 10.11.6 but not on 10.13.1 @SiddRamesh Does your 7650M work like OOB on Sierra?? Link to comment Share on other sites More sharing options...
