Hi

As I understood Fermi cards < 570 does not have out of box support for OpenCL, this has to be enables manually
. I know that Multi-Beast for Mountain Lion has the patch, have not tried that one on 10.8.3 but here is what I did to get my card working 100%.

I am running as iMac12,2, edited my AGPM.kext(AppleGraphicsPowerManagement.kext) in the respective location and then patched the GeForceGLDriver.bundle with the following perl command:

sudo perl -pi -e '$c+=s/\x8b\x81\x1c\x0c\x00\x00\xeb\x06\x8b\x81\x20\x0c\x00\x00/\xb8\x02\x00\x00\x00\x90\xeb\x06\xb8\x00\x00\x00\x00\x90/; END { printf "%s: %d substitution%s made.\n",($c==1 ? "Success" : "Error"),$c,(!$c || $c>1 ? "s" : ""); $?=($c!=1); }' /System/Library/Extensions/GeForceGLDriver.bundle/Contents/MacOS/libclh.dylib

this enabled OpenCL on my gtx 560 non-ti and I have tested it with LuxMark 2 with 100% success.

I have also repaired all permissions after the modifications and rebooted.

Hope this helps someone out there struggling.

Greetings...
