Thread: Ati Radeon 4350 with Mountain Lion

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 !

Help please!!! Anyone tried installing Mountain Lion with this card?

I have the same problem plz help

Please.. help!

Adding your device ID to the ATI 4600 kext gets normal resolution

Hello, I've just read here Kexts that ATISupport (7.0.2) is compatible with ML so my question is:
1) How and where do I find that file?
2) How do I install it?
3) Where do I find the ATI 4600 kext and how do I modify it?

Thanks.

P.S.: I'm very new to hackingtosh, in fact, I have never use a mac before, so please, be patient

I follow advice of 'Here to help' 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 two screens config, using DVI and HDMI ports.

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

ATI4600Controller.kext.zip

Worked perfectly for me! Thank you very much!

Hi Martinlbb:

I am also on Mountain lion 10.8.2 with Radeon HD 4350 card, same device id 0x954f. But after installing your kext using kext utility, I couldn't boot. I ended up into snow flake like screen. Do you have any idea what should I try?
Without modifying ATI4600.kext, I can see I have AMDsupport(ATIsupport.kext) and ATIRadeonX2000.kext loaded.
I have ATIsupport.kext version 8.0.0. what version do you have and does it matter?
Thanks in advance
