Hey guys I am running 2 GTX 780 Ti's in my mac pro. I had everything working but now that I have updated the Nvidia drivers my CUDA isn't being recognized in the software I use. Anyone know how to fix and which previous drivers I need?
Hard to give advice when you give no specifics! The latest Nvidia Drivers are:
Web Driver - 346.01.01f01
Cuda Driver - 7.0.35
Available Here:
http://www.nvidia.com/download/driverResults.aspx/83647/en-us and
And Here:

The latest 346 driver does break Cuda if Cuda 7.0.35 is not installed.

Ok, FWIW, even with both of those installed, my dual 970's run under the web driver, however, Cuda is broken. Neither CUDA-z or blender even see the GPU's Cuda Z reports "No cuda devices found".
Now this may be specific to me, as I originally installed the the first video card (a flashed GTX 680 4 GB) on the very day the 3rd security patch came out, so I updated from 10.9.x to 10.10.2 on that day, and before I could change the settings during the install OS X went out and got the security patch and installed it as part of the OS install (taking me to 14C1514), so I had to unpackage the NVIDIA installer, bypass the hardware and software checks so it would install, and manually fix the build number so the driver would run.
Now I could have done a complete reinstall of 10.10.0 at that point when 343.02.02F04 came out to fix all this as that one would run on 14C1514 which is what I'd have ended up with at that point, and in fact I did try that, but used migration assistant when I did, and whatever I'd broke under the hood getting 343.02.02F03 came along for the ride. I had to use migration assistant as I really wasn't looking forward to reinstalling Logic Pro from scratch (all 14 DVD's of it), Aperture (and all my various custom metadata presets and workflow related stuff) and my work VPN and email stuff etc.
So after migration assistant did it's thing the 343.02.02F04 drivers would not work, so I edited the system.version.plist back to the build prior to 14C1514 in order to the the 343.02.02F03 drivers to install, then reedited the system.version.plist back to 14C1514 so the Nvidia pref pane would reinstall 343.02.02F04. That actually worked and is where I was until 346.01.01f01 came out.
At any rate, the combination of 346.01.01f01 and cudadriver 7.0.35 is NOT working on my box, and I'm somewhat fearful I'll have to wipe the entire boot volume and start over from scratch at some point to get the drivers to play nice, as something went awry during that process.
I sure wish to hell Apple would turn off the "we know more about what you want to do with your box than you do" during a fresh install and NOT just go out and grab and install updates whether you want them to or not.
While you can disable the auto install of software updates AFTER you've done an install, there's no way I know of of preventing it from doing so DURING a fresh install from scratch.
The super annoying thing about all this? For years one of the main reasons I've been a mac guy is I didn't have to jack around with this sort of crap. I always took a certain pride in not having to go through all this tweaky crap the windows people had to deal with. And now, I'm having to do exactly that just to get the damn box to do what I need it to do.
At any rate, at least I'm able to render.. For now.
