In Topic: Sierra - Nvidia (GTX970) - Black Screen at login

12 October 2016 - 02:50 PM



I am using SMBIOS 12,2

As I have an Intel Sandy Bridge i7-2600k

GFX card is an Nvidia GTX970


I have a fresh install of Sierra from USB, not an upgrade.

I installed Clover, installed my kexts, everything boots to desktop, etc. Works fine. 


However, after installing the NVIDIA web drivers, after enabling and a reboot, it gets to the login screen and the screen goes black.

I think the system, is up and working. If I proceed to blindly enter my password, the HDD activity lights go nuts, etc. 

Somehow it's just not outputting the display.


I have: 

  • Installed the Nvidia web drivers (367.15.10.05f01 for 16A323)
  • Enabled the Nvidia_web startup in my config.plist
  • Removed the nvda_drv=1 from the boot arguments 
  • Removed the nvda_drv=1 from the NVRAM
  • Tried adding Mac-942B59F58194171B (set to none) to my /S/L/E*/AppleGraphicsControl.kext/Plugins/AppleGraphicsDevicePolicy.kext/Contents/Info.plist


I am at my wits end. I have no idea what else I can do. 


I would really appreciate some help.

Thank you for this Micky1979 tool.  :)
I got Clover and macOS Sierra in a pendrive without any problem, after I installed it on an external drive and was also well, when I installed nVidia drivers had no graphics acceleration, I changed the SMBIOS I had it in iMac 14.2 and put the iMac 10.1 and now I have graphics acceleration. Only I have a problem, that the internal disks I get the yellow icon and do not know how to solve it, otherwise fantastic. Thanks again, it is wonderful how it works and is very intuitive.
