Hi, I wanted to share my experience, as I just had a total success installing the Nvidia Web Drivers on OS 10.9.3 and adding a second Screen.
Here's my Setup:
Gigabyte Z87X-D3H
Gigabyte GeForce GTX 660 OC
OS 10.9.3
I had CUDA already installed (although I dont remember which version. I guess smth about 5.XXX)
I read this whole thread and just went for it
- Graphicsenabler kext remained on "no" all the time
- I downloaded the WebDriver-334.01.01f01 straight from the nvidia homepage.
- Then I turned of my Hackintosh and unplugged my screen from the graphic card and plugged it to the mainboard (I didnt remove the card)
- Then I booted normally with the flag nv_disable=1 and installed the Driver.
- After the installation I restarted again with the flag nv_disable=1 and activated the Driver in the menu bar at the top.
- Then I turned the pc down and plugged the first screen back to the gtx 660 and I also plugged my second screen to the second analog output of the card (I dont know if hdmy works, as i dont use it)
- I boot the hackentosh normal, without any flag. Both screens work fine.
- Lastly I went into the CUDA menu and updated CUDA to the current version (6.0.46)
- Now everything works fine.
I personally didnt get any improvement in my LuxMark Benchmark. But both my screens work over the GTX 660 and Mavericks finally recognizes my card as "NVIDIA GeForce GTX 660 2047 MB". Before It showed "gtx 660 0 mb".
I hope I could help
Good luck to everyone
(Theoretically I guess I could plug a third screen to the Onboard graphics. But I cant try.)
