Black Screen After 10.10.3 update

[Manofstyl3]

On the image it is only showing "n" it should be "none"

Disable Integrated Graphics on BIOS
Set Graphics Card/PCIe as your Primary Video Adapter/Initial Display Port on BIOS.

Also ensure that the Nvidia, Intel, ATI graphics injections are disabled on config.plist.

Try to boot without caches.

Going through your instructions... the issue with the "n" in the playlist is that when I type "none" and SAVE the file... I go back into the file to ensure it is GTG and it automatically changes the "none" to an "n". For ****s and giggles... I did this 6 times... the 6th time worked! We are GTG there now...

I did a restart after correcting the file... same issue.

SO... for the bios instructions... where do I do that in my bios (disable integrated graphics)? (screenshot 1, screenshot 2, screenshot 3)??? Not seeing any options for graphics in both EZ and Advanced modes...

For the "Nvidia, Intel, ATI graphics injections are disabled on config.plist"... where is this file located?

Thank you again... apologies I know these are rookie mistakes, I'm just new to customac programming/configuration.... but I learn quick!

Thank you Jithin, standing by kind Sir. -Joe

I swapped out the video card with my original (was swapping out diff ones to see if that would work) and KABOOM!!!

Unpack zip and use the Kext utility for installation

Thanks man. I now have my video back w/o having to use nv_disable=1

After upgrading to 10.10.3 I needed to boot with nv_disable=1, install the latest NVidia WebDriver-346.01.02f02.pkg, replace AppleGraphicsControl.kext with the patched one, rebuild caches and reboot. It worked. I have been using Clover (no InjectNvidia, nvda_drv=1), MacPro6,1 smbios, and connect through DisplayPort.

But ...

when I replace my GTX 670 with a GTX 980 I get the black screen again

Am I supposed to do anything else for GTX 980 ?

The kext S9000 posted worked for me like a charm with my GTX 980

Many many many thanks!!!
I had this problem with my UHD monitor (UP3214Q, definitely not the best UHD monitor for hackintosh...), any problems with my cinema HD 30", the fix #48 give me my UHD monitor back.

For those who could have the same problem than me:
GraphicsEnabler=No; IGPEnabler=No, no nvda_drv=1
System definition: Mac Mini 6.2 (One of those who work with the UP3214Q)

And everything is good
Many thanks again

PS: I cannot use the Web Driver, which is not a problem for now, but I plan to buy the GTX Titan X and I will need to use them, any idea guys?

The instructions had made it work for my GTX 670, but when I replace the card with a MSI GTX 980 Gaming the screen blacks out shortly after loading NVDAStartup. I gave up as I didn't want to start from the beginning - I have too many hacks (for USB 3.0, for Audio, for SandyBridge-E power management, for sleep, etc). I 'll keep the card for the future, once I feel 12 cores is not enough and need to build a new system I will use it.

I tried everything you guys said, and I still have the black screen.
I booted in nv_disable=1
Got the latest nVidia web driver.
GraphicsEnabler=no
IGPEnabler=no
Fixed the kext using kext wizard
Fixed permissions and updated cache
And nothing.
I still can only boot with nv_disable=1
