R9 290X with MacOS Sierra

[ReMiii40]

Hello guy, I have a Gigabyte R9 290X, and I have a black screen when I want boot for the first time on my HDD. I don't have iGPU (i7 920 1366 with Intel x58 so no Intel graphic card). How can boot ? Which options I must change in Clover ?


Edit : The first boot work only with Inject ATI, fb Lagotto, and safe mode + verbose mode

We don't have any solution for systems without helper GPU yet. I'd stay on El Capitan...

I can use MacOS Sierra in Safemode (with only R9 290X), why ? :/

Edit : DP work with no modification, I try to change baladi (amd8000controller)

The issue occurs when the accelerator kext (AMDRadeonX4000.kext) loads (which shouldn't happen in safe mode). You can remove it to boot up without black screen, but obviously would lose acceleration.
