KP with my config.plist for the 530 integrated GPU

[Coherent]

I am having issues with getting acceleration working with the 530 card. My build is almost identical to PastryChef's Golden Skylake Build except for the memory and (current) lack of discrete video card. I have tried adding two different AddProperties blocks and both allow the machine to boot fine but they don't fix the graphics issue by themselves. The problem is when I add the ig-platform-id block. I have tried values of 0x19120000 and 0x191B0000 with both of these AddProperties blocks, and all 4 combinations cause a kernel panic. Using 0a206080 as a value doesn't cause a kernel panic (yay) but it also doesn't fix the screen flickering (aww). I set the iGPU to 512mb which removed a black bar that I had been seeing at the bottom of the screen but the flickering persists.

I am attaching a currently working config.plist without acceleration and my latest attempt with the AddProperties and ig-platform-id added which is giving me a kernel panic. Thanks for your help!

I finally figured it out. The problem was that I was using iMac 14,2 instead of iMac 17,1. Here is my working config.plist in case someone else gets stuck like I did.
