Hello everybody,
I installed MAC OS X El Capitan 10.10.2(15C50) and it worked with no problems(except for audio and graphics) till I installed Nvidia's web drivers, So this is what happens:
It boots and the system works but the monitor shows me "No Signal" with a black screen, I have tried to boot using "nv_disable=1" and it worked but I wanna use my graphics card and get the full 1920x1080 resolution.


This is my rig btw:
CPU: Intel Core i7 5820k
Motherboard: MSI X99a Raider
Graphics Card: Gigabyte GTX 970 G1 Gaming
RAM: Kingston 16GBs DDR4 2133mhz

I would appreciate it if someone helps me out,
thanks.
 
Thanks for your help, but it didn't work for me.
Anyways it is a MacPro 6,1

Did you follow all of the steps? The "no signal" but the computer still booting is a classic sign of MacPro6,1 and the Nvidia Web Drivers. You can also try this Clover patch which does that same thing but without modifying the kext directly and is persistent through updates: https://pikeralpha.wordpress.com/2015/11/23/patching-applegraphicsdevicepolicy-kext/. I personally have not tried this method as I use iMac14,2.
 
I'm sorry but how can I do that, I mean where to put that code he wrote?
I don't really know how to patch the kext so I'll be very thankful if you can help me.
