Fix for Nvidia 8400GS in Mountain Lion

[MacMan]

Without out one to test I can only speculate why it doesn't work.

Looking at the card database it just might need it's device id added to NVDANV50Hal.kext if it's a 2nd generation 8400GS.

I'm quite new with thus kext stuff... Please correct me if I'm wrong

- Fresh install of ML
- Boot using the bootloader present on the installer usb key with -x
- make a backup of /System/Library/Extensions/NVDANV50Hal.kext "elsewhere"
- edit /System/Library/Extensions/NVDANV50Hal.kext/Contents/Info.plist
-- modify the IOPCIPrimaryMatch string list according to the PCI id of my card
- report success or failure here

Will I need to do something to make sure my modifications are taken into account be the system at reboot ?


Thanks
Etienne

You will need to force update of the kernel cache. The easiest method is in Terminal is to do the following:

sudo touch /System/Library/Extensions

Will this fix the login screen "5 minute hang"? As that is the only issue I'm having with my 8400GS under 10.8.2
