    I am having problem #4. I use MacPro 6.1 and after updating to 10.10.3 and installing nVidia drivers my monitors says no signal. I tried to use your guide but I was not able to located <key>ConfigMap</key>.
    What am I doing wrong? here is a screenshot of my Info.plist for AppleGraphicsControl.kext

    You need to dig deeper to find the right info.plist. Once you have shown the package contents of /System/Library/Extentions/AppleGraphicsControl.kext you then need to keep going to /Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/info.plist.

    Solving NVIDIA driver install problems

    @Stork:
    "Good news. :thumbup: Now, don't forget to sacrifice a chicken to the computer gods each day. :)"

    Ran out of chickens. Today, normal startup doesn't work. BIOS set to "Optimized Defaults," except Memory to "Profile 1" (1600 MHz DDR3 setup), "Initial Graphics" to "PCIe," "IGFX" to "Disable," "ERp" to "Enable" (turns off external USB power when shut down, which disables power LEDs on external USB switches).

    Boot process goes like this (with GT 740 card installed): Press power on button; normal boot up to and through the TonyMac screen, Apple logo shows on white screen with progress bar, which makes it about 1/3 complete, then screen goes black, video shuts down, video comes back up, black screen with active progress bar, progress completes, then screen goes white. Cursor is frozen, keyboard is frozen. Then I press the Restart button, screen goes black, then white, then I finally get the desktop.

    Using "Shutdown" in Mac OS X kills video (black screen), but the computer power never goes off until I press and hold the Power button on the computer.

    The above varies; sometimes even restarting after the screen goes white (above) results again in a white screen. But at least half the time, the desktop comes up and computer operates normally (until shutdown).

    More suggestions? Please note that I have already once used my Unibeast USB stick and using Disk Utility, with the GT 740 not installed, re-partitioned my "Yosemite" SSD, made a fresh install of Yosemite 10.10.3, ran Multibeast with no "Graphics Enabler" or "IGFX" flags, and everything worked perfectly with no GT 740 card. Adding the card (whether or not setting up the BIOS for the card, as I wrote in my original post) causes the booting and shutdown screw-ups.

    Thanks for reading, & sorry to use your bandwidth!

    You will need to use kext-dev-mode=1 after modifying the kext in problem #4. Also you might need to rebuild kernel cache. I'll update with the additional steps.

    Spend a little more time than usually but all works now just fine now. Used solution for problem #4 but it didn't helped right away. Rebuild kernel cache, fixed disk permissions and reinstalled nVidia drivers. Reboot and I'm back in business on 10.10.3 )
    Thank you for the guide.

    I added rebuilding kernel cache which is all that should be needed. Glad it worked out for you.

    Thank you so much, slim.jim! This thread, and specifically this boot flag, allowed me to run 4k on my GTX 980! I was having serious troubles getting the web drivers to work

    Solving NVIDIA driver install problems

    Thank you very much! This post helped me solve my no monitor signal issue after updating to 10.10.3 and re-enabling the Nvidia Web Drivers. I just wanted to point out a misspelling here, it's "Extensions" instead of "Extentions".
