Cool, good to hear rominator. No rush with the kexts - whenever you get the chance!

After 2 days of trying different combos of non-working kexts I think "almost" isn't the right word.

Yeah, admittedly for you that's probably not the right word. That said I've got PM's from 3 people over the past 2 days confirming that their 6870's are now working. The shutdown/restart issue is still there, though - so there's still a bunch of issues. Would be great to hear of success with the 6970 too.

Since you have your hands on the new MBP's disc, maybe you could tar up the following if you get a chance:


I'm still not entirely sure what messed up the kexts in the first place.

Some benchmarks (for jpa).

Rominator here from Netkas forums.

I have been going nuts trying to get a 6950 and 6970 running in a Mac Pro.

I was using the kexts linked here and noticed that even when I used a Radeon 5870 I got NADA...a card that worked BEFORE I installed these MBP SL kexts. I then noticed that 3000.kext hadn't loaded.

On a hunch I compared them to ones I just got from an install disc image. I noticed that the one linked here is a little light. 157 bytes light to be exact.

Further examination shows that the _CodeSignature folder inside contains Aliases for CodeDirectory and CodeRequirements whilst the ones I got from Install DVD contain files of 153 bytes and 12 bytes for these same two files. Right clicking on the alias files in files linked from here to find original goes no place.

I believe therefore that these files are somehow corrupt or incomplete, and this may explain why nobody has been able to duplicate the OPs success.

Could these be symbolic links that haven't been kept whole?

Sadly, by the time I noticed this my install is now all buggered up so it will take me time to get it all back together, but I am hopeful that the poster can get to the bottom of this and either remove the posted files or post correct ones.

I have attached the specific kext I mention, it seems likely that if this one is buggered up, others may be as well.

If I am in error I apologize in advance.

EDIT : I can choose the file to attach but the green "upload" button is dead to me. This may be due to fact my remaining good OS is Lion, which is a tad buggy. Will try from another machine shortly.

The symbolic links in my upload are definitely broken. Unfortunately, they were also broken when sent to me by the helpful gentleman with a new MBP. However, they can still be made to work (I almost forgot about this step).

Basically, rebuild your kextcache WITHOUT authentication, and things should work. There are still other issues (sleep, shutdown, restart etc.), but at QE/CI etc. will work.

To rebuild your kextcache without authentication run:

kextcache -z -v 1 -t -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions

The -z switch disables kext authentication. I'll try to get our source to send us on the kexts again, this time tar'd instead of zipped to preserve symlinks.

The SL shutdown issue doesn't seem to affect Lion, but it happens to me in SL also. I might try the new MBP's kernel too (it's different from 10.6.6's).

Works in this card??


Snow support this?
OpenGL 3.1
OpenGL 3.2
OpenGL 4.0
OpenGL 4.1

Suport all?

Lion allegedly supports 3.2. I'll post some benchmarks over the weekend, and I have no idea if it'll support that card. Although it should, 6870's have the same reference design.

Got the same as the guy above. 6850, installed kexts and got the installed improperly message. I used Kext Helper to install btw. Proceeded to install Chameleon RC5, and a modded boot file I found in another thread. It also advised me to dump my ROM, and place it in the Extra folder.

Edited the .plist to show UseAtiRom=Yes, and GraphicsEnabler=Yes.

Booted up, and got black screen, and full fans.

Would it have worked with GraphicsEnabler=No


You can remove UseAtiRom & GraphicsEnabler from your boot plist to disable the injector.
