Hi everybody. Sorry if my English is bad

I installed Mountain Lion GM on my PC, and all works fine, except for graphic and audio.

My graphic card is Ati Radeon 4350 512MB (0x954f).

I've problems with this card, in fact the graphic is very slow and when I open launchpad, or Mission control, or Centro notifiche, or the top sites tab on safari, ML become very slow and shows lines on the monitor.

Humm... i think the kext is wrong, or i haven't qe/ci.

I tried installing some kexts i found on the web but the boot stop and didn't continue... the same thing is safe mode...

so I reinstalled ML three times...

I ask help you... because i don't want reinstall ML another time... i want the exact kext...

Can you help me... please !

Hi

I managed to let work AMD Radeon 4350 (512 Mb) on Mountain Lion.

I follow advice of 'Here to help' (from os86 forum) and edited Mountain Lion 10.8.2 ATI4600.kext to add HD4350 support (id = 0x954f).

It worked well, with no need of any other hacks (like modifiy org.chameleon.boot.plist).

Just work out of the box!

I tested it with dual screens config, using DVI and HDMI ports (24" and 17").

Here is the modified Kext (just added 0x954f1002 to info.plist at line 62).

 ATI4600Controller.kext.zip   104.48KB   56 downloads

If you have different model ID, I can add to ATI4600.kext, if needed.

Enjoy
