Hello,

I have a problem with my radeon hd 6790. I can boot with the card but I don't get graphic acceleration in mavericks. Are you have any ideas ? I integrated the id of the card in the kext. Next day I will try installing Yosemite and will have a look.

Best Regards from germany

Hi,
Last night I managed to get Yosemite installed. After installing all needed kext I edited the AMD6000Controller.kext. I put the id of my card into kext and get 1080x1920p working.But no graphic acceleration at all. Do you have any tips? I think there is no way to get the card fully working.

Hi,

There is no Mac Pro 8.1. The newest mac pro is the 6.1. Do you mean 6.1?

Beste Regards

Alex


edit:

My SMBios in Clover was from the beginning Mac Pro 6.1. The boot args does not show any effects.

hi

 

you have to add your device-id (0x673E1002) into the Info.plist from AMD6000Controller.kext and AMDRadeonX3000.kext

 

AMD6000Controller.kext

 


            IOPCIMatch
            0x673E1002 0x67681002 0x67701002 0x67791002 0x67601002 0x67611002 0x67501002 0x67581002 0x67591002 0x67401002 0x67411002 0x67451002 0x67381002 0x67391002 0x67201002 0x67221002 0x67181002 0x67191002 0x68401002 0x68411002 0x67041002

 

 

AMDRadeonX3000.kext

 


        AMDBartsGraphicsAccelerator
        
            IOPCIMatch
            0x673E1002 0x67381002 0x67391002 0x67201002 0x67221002

 

 

repair the permissions and rebuild the cache

 

boot with:

 

Graphics
    
        Inject
        
            ATI
            

            Intel
            
            NVidia

@cyberdevs

 

I'm glad for you - just a question, manually device-id injection or through clover patch on the fly?

I added the device-id (0x673E1002) directly to these kext files AMD6000Controller.kext and AMDRadeonX3000.kext and then replaced them in the S/L/E

 

I repaired the permission and rebuilt the kext cache and after reboot I had a working AMD 6790 GPU.

Hi, Cyberdevs,

Is your HD 6790 graphics accelerator works in the latest update high Sierra 10.13.4 as well

thanks

 

Sorry for the delayed reply. I haven't tested the HD 6790 in High Sierra yet but I'll let you know when I test it.

thanks, anytime when you have the time please.

For High Sierra there are three kext files which need to be patched:

 

AMD6000Controller.kext

AMDRadeonX3000.kext

AMDLegacySupport.kext

 

Add you device ID to those kexts and rebuild kextcache and repair the permission and reboot.

In the config.plist just add InjectATI=True and add the 6000 to "ATIConnectorsController" under the "Kernel and Kext Patches" and reboot.
