Hi,
I got my Titan Z working in yosemite (hackintosh) stable, except that octane only sees one of the GPUs.
Is there an easy way to get both GPU running in OSX?
Thanks,
Nick

I'm running Yosemite,
Gigabyte motherboard.. (hackintosh)
2 GTX780
1 GTX Titan Z
Latest cuda drivers, and latest nvidia web drivers.
when I boot up in window octane list the following GPUs
GTX 780
GTX 780
TITAN Z
TITAN Z
when i boo up in OSX, the same hardware... the second GPU on the titan does not show up.
GTX 780
GTX 780
TITAN Z
Something to do with OSX not recognizing dual GPU cards. But some people have made this work..
do you see 2 titan z in ocatane or only one?

Got it working!!!
This is for anyone who has the same problem.
1) updated bios on motherboard
2) boot flags
<key>Kernel Flags</key>
<string>kext-dev-mode=1 PCIRootUID=1 nvda_drv=1</string>
<key>GraphicsEnabler</key>
<string>Yes</string>
Used Mac Pro 3,1 as system definition.
