AMD R9 270 doesn't work properly after 10.10.3 update

[SOLVED] AMD R9 270 doesn't work properly after 10.10.3 update

10.10.1 worked fine with my R9 270 after installing AMD7000Controller and AMDRadeonX4000 with KextBeast.

As of updating to 10.10.3, everything else works after MultiBeast except the graphics. I get the glitchy, slow, low-resolution 3MB graphics. I've tried reinstalling the graphics kexts with no luck.

Asus P8Z77-V LX, Core i5-2300, 16 GB, AMD R9 270

(I don't really understand how Hackintosh booting works, MultiBeast installed Chimera 4 but it still says Chameleon 2.2 at the boot options screen, but I haven't messed with it since everything works, including iMessage)

Any help would be much appreciated.

Chimera is a branch of Chameleon boot loader.

As you had updated to 10.10.3 from 10.10.x, no need of re-running Multibeast.

Try booting with flags "GraphicsEnabler=No IGPEnabler=No -f"

Check my answer for 7770, obviously you have the similar problem:

No effect.

I noticed that the AMD7000Controller.kext and AMDRadeonX4000.kext in /System/Library/Extensions aren't loading.

I tried to load them with kextload (recommend somewhere) and these are the errors I got:

Requesting load of /System/Library/Extensions/AMDRadeonX4000.kext.
/System/Library/Extensions/AMDRadeonX4000.kext failed to load - (libkern/kext) link error; check the system/kernel logs for errors or try kextutil(8).

I am not sure what the problem with the kexts IS. I've repaired permissions and rebuilt kextcache so I am assuming the files themselves are somehow invalid. They are however to the best of my knowledge the same ones that worked just fine on 10.10.1.

There is one solution update (Post#16): http://www.tonymacx86.com/yosemite-...update-black-screen-cursor-2.html#post1018020

Some guys got enable the QE/CI after following this. Make back up of native kext then try the above linked solution.

Thanks for the link.

Actually, my file already had the "old" values to which you're supposed to change them, because it's the old file that worked on 10.10.1. If there's a new version specifically for 10.10.3 then I haven't been able to find one.

Who all are installed the old version kexts, now they are unable to enable QE/CI... LOL

Better make the changes on the 10.10.3's kext.

Where do you get the new version? When I google for it, all I find is one on github from 2014.
