GTX 760 - Display going to sleep.

[seb235]

Hi 

Today I decided to install macOS Sierra on second partition, and I can't get it to work because of my graphics card - Nvidia GeForce GTX 760 2GB. System is booting as it should, then my display is going to sleep and I can't do anything. I'v tried on PB 1 with and without Nvidia Web Driver, the same issue on Public beta 2.

Only way to boot system is "nv_disable=1" flag. (to see anything on the screen)

El Capitan is working great on this system, so something is wrong with nvidia graphics support in macOS Sierra.

 

I do some investigation, tried use DVI-D instead of Display Port - The same issue display went to sleep.

As far as I can tell system is booted up correctly because I can hear a sound from speaker when I hit key on the keyboard, something is wrong with input configuration. But I can't fix it.

Any ideas? 
Please help.

What Mac model? iMac15,1/17,1/MacPro6,1 need AGDP to be patched (or renamed ACPI devices).

That's not working, I tried a few SMBIOS with and without patched AGDP.

I'm in the same boat with EVGA GTX660, as well as many others are, but it seams that nobody has a clear answer to that issue yet.

I upgraded 10.11 to 10.12 and the display adapter GTX 760 is recognized without any issue.

I didn't do anything special. It works with Apple supplied kexts as well as from NVidia.

If this help, in smbios the model is set as MacPro5,1 if I remembered it correctly as I am not in front of that computer now.

 

OT: The only problem I have is related to AppleHDA, there is no sound output device to select on Systems Peferences, even though I could see the ports on System Information.
