It's supposed to support all FX Processors. Now, what I suggest is backing up your original Mach_kernel in case something goes wrong. 

Also, you have LION and not MOUNTAIN LION - right? 

Yes Lion...


Voodoo didnt work for me just gives me krrrrrrr krrrrrrr noise...:( will try realtek 892...


And i am getting QE\CI problem :(

hi  guys

 

just to clarify some things

 

@ghost9685 -> you said have HD6770 perfectly working with QE/CI enabled under OS  X Lion?

 

I doubt it is possible because this card is supported since OS X Mountain Lion

 

there's 3 way to have QE/CI enabled

 

1) like you did, i.e, just edit 3 kexts with your ID (0x68BA1002)

 

2) dsdt inject method (my favorite  :P )

 

for more details, see this post: http://www.insanelym...-mountain-lion/

 

3) flashing your HD6770 to HD5770, your graphics card will work OOB -> Out Of Box

kexts did change in 6.8 and thats why i up'd 6.7 kexts back in 6.8 betas. in 10.7 they started with RadeonFramebuffer and we didn't need injectors anymore so it should be supported just by having ids added.

i don't, i have a 5750. was just letting you know that its been supported since 6.7 when you said 10.8.

 

you could also look back at netkas blog, i seen you had a 4830 back then.

First, you will always have problems with graphics on AMD cpu unless 10.9 brings a fix to the issues from using a patched kernel for amd. You should only need your id in the the controller kexts to get proper res change. Since 10.7 you should only need correct ids in kexts for support. How did you edit your plists and are you sure they are being loaded?

sorry joe75 but I don't think Rominator talked about HD6770 support in OS X Lion or SL, you know as HD 6770

 

maybe he talked about what Netkas said, i.e, to flash HD6770 into HD5770

 

I can confirm there's no support for this card before OS X Mountain Lion

 

I was able to do it via editing 3 kexts (ATI5000Controller.kext, ATI6000Controller.kext and AMDRadeonAccelerator.kext) with my ID (0x68BA1002)

 

 it's just recently that RampageDev told me that it was possible to do it via dsdt inject method (but it works only with HD5770 ID, 0x68B81002), so no more need to edit kexts

 

but this works only on ML and Mavericks

 

;)

You are wrong..

 

http://netkas.org/?p=679

 

I posted the kexts and don't understand why you need to argue this? Just because you couldn't get it to work doesn't mean its not supported.

we don't talk about HD6870 but HD6770  :wallbash:     (like this topic)

 

HD6770 is an authentically HD5770 card, only ID's differ (0x68BA1002 / 0x68B81002)

 

this is nothing to do with HD6870

 

Just because you couldn't get it to work doesn't mean its not supported.

 

-_-   no comment

 

just because HD6870 is supported doesn't mean all HD 6xxx are supported

 Whats not polite? telling you that you're wrong?

 

and yes 6870 does mean that a lower 6770 is supported. based on 6700 being rebranded we could say it even had support prier to 6.7 :P

 

Lets also note that the mid 2011 iMac with 6750m shipped with 10.6.6
