GTX 970 - Black Screen after Nvidia 346.01.02f01

Hi,
Got a question. I have a Mac Pro 6,1 profile on this X99 Setup and obviously the Web Driver complains about "Computer not supported" so I tweaked the distribution to get that working.

The PNY 970GTX has 3 mini displayports, and 1 DVI and what looks like a mini-HDMI. Only ports that work are 1 mini displayport and the DVI. Is there any way to get the unrecognized ports working or is it a side effect of using a MacPro6,1 SMBios? Or just the nature of this being in beta?

It very well could be a side effect of using the 6,1 profile. Try switching to iMac14,2.

Thanks Slim, gave a iMac14,2 and a MacPro5,1 a shot. No change to how the card is reacting. I didn't change my Serial Number though as I didn't want it to jack up my working iMessage/Facetime, but maybe I should change it too?

I notice the Web Drivers appear to be getting used, but the Nvidia Pref pane is switching back to OS Default Drivers. It also seems to register the card as a PNY GeForce GTX 970 0 MB.


Edit: Changed serial number - didn't effect my iMessage, but didn't fix video card outputs either.

MacPro6,1 required a PCIRootUID=1
MacPro5,1 required a PCIRootUID=0
iMac14,2 required I remove PCIRootUID

Rest of the normal args: nvda_drv=1 kext-dev-mode=1 darkwake=0 dart=0

Fixed my issue - I was injecting Nvidia via clover. I turned that off and all the monitors came on.
I left myself with a MacPro5,1 profile for now. Not sure if a 6,1 would have any bonus to the motherboard or not.

I also notice if I attempt any overclock Clover starts up complaining about "Couldn't allocate...." and gets stuck. I left the TweakerAI stuff alone and turned Turbo on for now.
 
Does anyone have a fix that works with a Chimera build??
 
Just reporting in to say this is working on my system (970 / 4790k / Clover)

I was booting fine with the Nvidia drivers with nvda_drv=1 with every definition except iMac15,1 and Mac Pro 6,1.

I went with the 15,1 definition by replacing this

<key>Mac-42FD25EABCABB274</key>

<string>none</string>

Modifying the AppleGraphicsControl.kext is working here!

Note - this may be placebo but the UI feels a lot smoother and less jittery on iMac15,1 and MacPro6,1. noticeable on dock hiding and UI animations.

Hopefully we can find another solution that doesn't involve manually editing kexts. Great work!

Cheers!
 
stuck at the same problem definition is 6,1
In my info.plist it says Config1 instead of Config2, tried changing it to none but now i can't reinstall the kext correctly. any suggestions?

Use Kextbeast or Kext Utility to install it.

Okay tried using kextbeast instead of Kext Utility witch i used before, but it still comes up with the same error massage saying "system extension cannot be used try reinstalling or contact..."

Did i miss something in the proces? View attachment Info.plist.zip

Edit: got the kext installed without getting a error, but still unable to use web drivers

Just use iMac14,2 and don't bother with all of the issues that come with iMac15,1 & MacPro6,1. There is zero benefit to using those.
