Solving NVIDIA Driver Install & Loading Problems

theallan said:
Hi all, I'm having a bit of a shocker with my first Hackintosh build (yup - welcome to the club :) ). I can install El Capitan (.5) no problem with the awesome instructions on this site - the problem is the Nvidia GTX980 I'm trying to use with it - I'm encountering problem 4 ("Monitor goes to sleep at the end of the boot sequence") but I'm not using one of the machine identifiers listed there, but rather MacPro3,1 (config.plist attached).

I'm confident that its problem 4 rather than a complete system freeze since I can use VNC from another machine to do a remote session and its responsive. When in the VNC session "About this Mac" shows the Nvidia card as correctly detected. Weirdly it also says "iMac (Retina 5K, 27-inch, Late 2015)". But I specifically selected "MacPro3,1" in MultiBeast and the config.plist appears to agree with that.

I tried the "Pike R. Alpha" fix, which you'll be able to see in the config.plist, but that had no effect.

System:

* Mother board: Asus Z170 Pro Gaming
* CPU: i7-6700K
* Graphics card: Asus GTX980 OC (4GB)
* RAM: Corsair Vengeance LPX 32GB
* SSD: Crucial 250GB

Anyone got any ideas? I'm at a complete lost!

After installing 10.11.5, I had to rebuild the kext cache and stuff, so that the Pike R. Alpha fix could do it's find and replace thing. VNC or Shared Screen let's you type the commands on another computer while the monitor is blank. But I'm using iMac17,1 so I don't know if that will help your MacPro3,1 problem. Did you check System Information report to make sure it's set to MacPro3,1?

Rebuilding kernel cache might help because his system is stuck using iMac17,1, as seen when he connects through VNC.
 
Hi guys, Thanks for the reply. I did try clearing the Kernel cache, and I've just tried it again - same result. And "About this Mac" still shows that it thinks its a 5K iMac. I don't understand where it is getting that from. At no point in MultiBeast or Clover have I set it to be that.

Even it was set to be an iMac, the Pike R. Alpha fix hasn't done the job.

Any other suggestions to try?
 
Well I just figured mine out. I did a fresh install and the graphics card decided to work now. Now to get my audio working...
 
These are the kernel cache commands I use:
Code: 
sudo kextcache -system-prelinked-kernel
sudo kextcache -Boot -U /
sudo kextcache -system-cache
sudo touch /System/Library/Extensions
Also, are you using the latest NVIDIA web drivers? The "NVIDIA Driver Manager" System Preferences panel will tell you if you need to update. If you do kextstat, you should see some "com.nvidia.web" kernel extensions in the output.

I think there was a recent change in Clover that makes it ignore the SMBIOS section of the config.plist if all the fields are not filled in correctly or new defaults were added for certain processors. I think you need to set the ProductName at least. The default type for Skylake processors is iMac17,1. Other processors have other default types. The default is MacPro31 for unknown processors.
 
Whoohoo! @joevt - thank you. I wasn't using lines 2 and 4 from your suggested cache clear. I also had to remember to not boot from the USB, but rather the SSD with the configured Clover on it. Brilliant - thank you so much!
 
When I install the Nvidia Drivers appears to me in the top bar the nvidia logo but on reboot is gone and it's like really has nothing installed as if everything falls to zero.

My video card is a GTX 750 Ti

Is there not a system preference pane either?

But if I click it gives me this error: unable to open the NVDIA manager (she asks me to try reinstalling it does not go anyway)
