Just got my GTX 560 and thought I'd share what information I've amassed to get this working on iAtkos L2. This is AFTER all the proper bios settings for power/ahci are met in addition to having the drive on the first sata port, etc. I'm able to use both monitors, microphone/headphones, and 5.1 through optical using VLC (movies)


I did check GF100 in VGA options on install




iAtkos L2 on Asus P6t Deluxe V2

my i7 920 3.5 overclock made it unstable in OS X ,dropped it to 3.0

DID AUDIO FIRST Kext Helper was preferable


On Board Audio

Install these 4 Kexts into S/L/E Used Kext Helper seems to work the best


Repair Permissions, reboot

Reboot with -v -f

I get 5.1 audio through the optical port (using VLC)

And Stereo and Mic through 3.5mm audio jacks on board

Modified the NVDAGF100Hal.kext/Contents/Info.Plist to include my device id 0x1201 under













The red is the GTX 560 (non-ti) device ID

Fixed Permissions, reboot

Download the GeForceGLDriver.bundle from here:




Use Kext Helper or something similar to install it to System/Library/Extensions, fix permissions, reboot

Now, to get OpenCL working totally,

So, open up a hex editor of your liking and do this: EDIT THE live file after taking permission of it.

open /System/Library/Extensions/GeForceGLDriver.bundle/Contents/MacOS/libclh.dylib (as root or with sudo)

find: 8B 87 1C 0C 00 00 89 06 8B 87 20 0C 00 00 89 02

replace by: 31 C0 FF C0 FF C0 89 06 31 C0 89 02 90 90 90 90


reboot is not required, but recommended

(I repaired permissions again just for good measure)
