Previously I had set the AMD device-id and the the AAPL,ig-platform-id of the iGPU set to 0x59120003 (03 00 12 59 after conversion) as seen below, but both configurations elicit the same behavior. I am also using a SSDT-GPU-SPOOF.aml file to spoof my AMD GPU. I am currently running without an AAPL,ig-platform-id defined as my SMBIOS of iMac18,2 matches my CPU such that it is unnecessary. This looks like the OS still thinks the GPU should be there and is requesting cycles, but not getting them. After sleep, the GFX AVG is locked to 0 and the GFX REQ is now stuck to 1.10 and doesn't move. Intel Power Gadget shows that Prior to sleep the iGPU is being utilized(GFX AVG>0), and that the OS is requesting usage of it(GFX REQ around 0.3). Safari also has a difficult time loading more complicated pages.Įven Hackintool appears to hang while trying to read the system configuration after this issue starts, and has to be killed. Microsoft Teams, for example, is unable to be opened to anything more than a white screen after I start to experience this issue. After I start experiencing the issue, VDADecoderChecker will hang until I hit Ctrl+C to kill it.Īfter sleep, I begin to experience issues with any application that uses GPU assisted rendering. Right after boot, VDADecoderChecker returns quickly and reports that decoding is supported. There are a few pieces of evidence that point to this: What I am seeing is that my iGPU (HD630/Kaby Lake) is working fine, in that I am running it headless alongside my Polaris card, and Intel Power Gadget shows it getting utilized on occasion when I play an h264 movie or try some other tasks that would typically trigger QuickSync to be used.īut when I either sleep the machine, or the display goes to sleep for any sort of extended period, the iGPU stops functioning properly. The one suggestion I received previously was to add a SSDT-SBUS-MCHC, but that did not change the iGPU behavior I posted something similar to Reddit a few weeks ago without much success.

I am hoping I can find some help diagnosing a particularly tricky issue I am experiencing with my Hackintosh Desktop.
