Rolback to working graphics .kext?


2 posts in this topic

Recommended Posts

I have an 8400M GS, I got it working fine under Kalyway 10.5.2 using NVkush.kext


In an attempt to get dual monitors working I edited the info.plist in the kext, deleted extensions cache

, repaired permissions and restarted.


The laptop now stops on booting at the grey screen with the apple logo and the loading circle going round on and on.


What I want to know is how I can reload the working kext from a cd or usb etc.


Is anyone able to point me in the right direction?

How comfortable are you from a terminal?


Your best bet is to boot from the install disk then once it's loaded up and at the install screen, plug in your USB drive, give it a few seconds then open Disk Utility from the Utilities menu and make a note of where your usb drive got mounted, should be something like /Volumes/<something> you also need to make a note where your actual install partition got mounted, if it didn't get mounted hit Mount in the toolbar.


Now you can open a terminal from the Utilities menu and copy the kext over, assuming you have the kext in the root of your usb drive it might go something like


cp -R /Volumes/<something>/<some.kext> /Volumes/<your install partition>/System/Library/Extensions/
chown -R 0:0 /Volumes/<your install partition>/System/Library/Extensions
chmod -R 755 /Volumes/<your install partition>/System/Library/Extensions


On the next boot use -v -F as the boot flags.


Good luck. Hope that helps.
