Upgrade Request

[Pepin]

The driver is up to date. With no updates available, I uninstalled the driver and reinstalled it as downloaded from the website. Same problem.

What connection/cable/adapters are you using from your GTX980? What monitor do you use?

 

[Pepin]

My monitor is an ASUS MG278Q connected via DisplayPort. I tried an HDMI and DVI cable and neither of them solved them problem either.

Can you boot using nv_disable=1 and manually edit AppleGraphicsControl.kext using the instructions from slim.jim below.

• Open Terminal

• Enter this command (it is one line)
  
  sudo nano /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist

• Arrow down to where you see <key>ConfigMap</key>

• For the iMac15,1 locate the board-id "Mac-42FD25EABCABB274" and change string below it from "Config2" to "none". For the MacPro6,1 you will do the same thing but for the board-id "Mac-F60DEB81FF30ACF6". For the iMac17,1 you'll have to see which board-id is declared in your config.plist SMBIOS: "Mac-B809C3757DA9BB8D" or "Mac-65CE76090165799A" or "Mac-DB15BD556843C820" and change the appropriate entry to "none".

• Save the file by pressing Ctrl+O, then enter.

• Exit by pressing Ctrl+X

• Rebuild the kernel cache using the following two commands in terminal:
  
  
  sudo kextcache -system-prelinked-kernel
  sudo kextcache -system-caches

• Reboot

So, none of the addressed lines apply to me, but I searched for the Board-ID listed in my config.plist file. It is Mac-27ADBB7B4CEE8E61, but the line underneath it already says 'none.' Should I have it say 'Config2?'

Edit: Disregard, I have tried that as well as 'Config1.' Feel like a bull in a China shop messing around with this kind of programming. But that just made me revisit the problem of not being able to enable the NVIDIA Web Drivers.

For the Nvidia drivers to work it has to be set to 'none'. I was ruling out anything that is causing your black screen issue. Could you upload you config.plist, attach it here so I can take a look. Thanks.
