Hi everyone,

 

I'm pretty new to hackintosh stuff but I have a pretty okay knowledge with programming. 

 

Essentially I tried installing the official version of El Capitan on my Mac Pro 3,1 running Yosemite and since then my ATI Radeon HD5000 graphics card has not been working properly. I can't fullscreen Youtube videos without serious lag and I can't run 3d graphics such as Unity3d.

 

I think there's an issue with my kexts. Here's the output when I run kextutil on AMDSupport.kext and AMD5000Controller.kext.

 

Can anyone point me in the right direction?

 

 

mac@macs-Mac-Pro:~ 

$ sudo kextutil /System/Library/Extensions/AMDSupport.kext        

(kernel) OSMetaClass: Kext com.apple.kext.AMDSupport class ATIController is a duplicate;kext com.apple.kext.ATISupport already has a class by that name.

(kernel) Kext com.apple.kext.AMDSupport start failed (result 0xdc00400a).

(kernel) Kext com.apple.kext.AMDSupport failed to load (0xdc008017).
