jaysen Posted June 9, 2009 Share Posted June 9, 2009 I'm running the following specs; Intel E8500 Asus P5Q Pro 4GB Corsair XMS Sapphire 4850 512MB I did a clean install using the OS X Retail DVD 10.5.5 9E25... Before installing any Kext i was able to get video at 1024x768 w/ no problems. I updated 10.5.5 > 10.5.6 > 10.5.7 - Up until the 10.5.7 update video was outputting just fine at the above resolution. Now, all I get is a Gray screen with white/black snow looking artifacts. Any help would be appreciated.

I think you have to install the 4850 kexts before rebooting the system (after installing 10.5.7 update). If you've forgot to install them, just boot in safe mode (type -x in darwin prompt) and install them.

Oh, and which Kext should I be using... I've seen/read the many tutorials however I am new to this whole Mac/OSX86 scene so a little guidance would be much appreciated...

I've seen/read the many tutorials however I am new to this whole Mac/OSX86 scene so a little guidance would be much appreciated... If you can't boot Leopard properly, boot it in safe mode (type -x in darwin prompt) and download this installation package: http://rapidshare.de/files/47140358/Natit.pkg.html The link was taken from this page: http://netkas.org/ Install that package that you have downloaded and reboot. I think it will work now. Link to comment https://www.insanelymac.com/forum/topic/170017-help-with-ati-4850-and-1057-update/#findComment-1174827 Share on other sites More sharing options...
jaysen Posted June 11, 2009 Author Share Posted June 11, 2009 Ok, so I tried your advice and ended up having to reinstall 10.5.6 Retail... Which I didn't care. So as of now, I am at a Clean Retail OSX install (10.5.6) with no updates - I've downloaded the natit.pkg you suggested. Double clicked on the package and it said installed. However I am only still able to get 1024x768 resolution... By installing this package was it suppose to allow me change resolutions and offer full support for my 4850 ? Again, sorry for the noob question and your help is much appreciated.

@ROBASEFR Posted June 24, 2009 Share Posted June 24, 2009 Try all de Pkg's on http://netkas.org/?cat=7 There a some problems with mobile HD4850 cards also ! Try eventually also the most récent Universal injector for Ati and Nvidia graphic cards: http://rapidshare.de/files/47335568/Enable..._cards.pkg.html Mine is working fine with a lot of versions of Natit.kext since the beginning but perhaps i'm lucky !

rsilves Posted June 26, 2009 Share Posted June 26, 2009 I bought a 4850 today and cannot make it work. (READ UPDATE BELOW) Can you explain me where to get the Natit kext that makes it work? I tried installing Enabler_for_Nvidia_and_multiple_ATI_cards.pkg which didn't work (shows apple logo then screen goes blank, I still am able to shut down the computer (blind) with the menu. Then I installed Natit.pkg and the same happened. I am not able to boot in -v or -x mode because I can only boot using my install DVD as a bootloader (HELP PLEASE). So I have to change cards on every restart. Annoying. + Do I need to delete any older kexts? I'll delete ATY_Init.kext (installed by Enabler_fot_Nvidia_and_multiple_ATI_cards.pkg), but any others that could be causing the issue? + My current driver is NVInject 0.2.1 with an EN7300GT Thanks, Rodrigo. UPDATE: WORKED doing the first 7 steps in THIS THREAD. And using Chameleon on a USB stick to enter -s, -f -v modes.
