Thanks gothic860. I miswrote that bit, I was doing it correctly. In the end I tried on top of a clean install and tada! Something must have been getting in the way in my old system. The first post-clean install showed 'Nvidea ASHLEY" as my card (progress of some sort!) after bashing away restarting and entering the terminal command numerous times, it worked! Then after a restart, it didn't! Things have settled down now and I am a happy Octane user. Thanks again and also to Mark and all who have developed this fantastic solution. Wucaiting, keep trying. It works! (Make sure that the nVidea driver is loading in system prefs not the Apple one)

I'm trying to get a 780 Ti working in a Sonnet Express III-R on a new mac pro 6,1 I have tried over and over and am close, with no cigar. Seems that NVDAStartup loads but the Kext signature will not validate I'm using WebDriver-343.01.01f03 and cudadriver-6.5.18, I get NVIDIA Chip Model in the Graphics/Displays System Information but not so much as a mention of the 780 Ti I've followed the instructions to the letter and ran sudo nvram boot-args="kext-dev-mode=1" and kext wizard until I'm blue in the face. Could any of the successful shed any light for me? The screenshot says its loaded but then not loadable. Way over my head... Cheers Diz
