set config.plist to inject intel=true and ig-platform-id = 0x19120000,
Is that ig-platform-id what gets the iGPU to run smoothly and with acceleration? Right now I inject intel but leave ig-platform-id blank and it's not very good at all.

Edit: Nope! At least not for my system. It makes my screen completely unusable. Have to fix my config.plist file somehow.:banghead:

There is no "runs smoothly" on integrated graphics yet.

If you inject Intel but don't set an ig-platform-id, I think it defaults to the ID for the HD 4600, which results in no acceleration. If you set 0x19120000 then you get acceleration, but with artifacts -- strangely colored menu bars and title bars, problems using Safari, App Store, and Preview, etc. It's usable if you have alternate apps (Firefox, etc.), and you can boot in Safe Mode to run App Store to do updates, but it's not exactly pleasing.

In the answer above I was suggesting going with Intel graphics just to get into the OS and do the post-install and make sure it's fundamentally working. Then you could move on to troubleshooting the Radeon card, once you know everything else works.

For anybody, I'd recommend Nvidia graphics for now if you're planning on using the machine a lot. I gather a Radeon *should* work, but I don't have any direct experience to help with troubleshooting.

Okay, fair enough. I tried the acceleration on my system but the artifacts were so bad I couldn't use the computer even if I tried. So I guess the integrated graphics varies pretty significantly between different hardware.

It looks like Pike released a patch for acceleration but it's not perfect. I haven't been home to try it yet.

His latest is confusing to me. I already see IntelAccelerator loaded. The problem I see is not with lack of acceleration, but with the artifacts. In any case, his suggested patch didn't do anything for me, but I'd be interested in whether it makes any improvement for you.

Hey man, I really appreciate your help, but nothing is working. Its giving me the exact same error message as before with the card removed, pc set to integrated GFX, and verbose. I tried giving it a fake CPU ID as Haswell but that didn't change anything either.

The thing is, the screen shot you posted before did not have any error in it -- that's all normal output.

Are you booting off the install USB at this point to get to the Clover menu? If so, can you put it in a different machine and post a screen shot of Finder looking at the EFI partition of the USB drive with EFI/CLOVER/kexts open in tree mode and all subdirectories expanded and files showing? And attach your config.plist as well.

I don't want to clutter up this guide with graphics chatter so see my reply in the Skylake test thread.
