NVIDIA Releases Alternate Graphics Drivers for macOS Sierra 10.12 Beta

[SammlerG]

generate nvram.plist on top of your boot device and

use Textedit to add:

<key>nvda_drv</key>
<data>
MQ==
</data>

and save file as nvram.plist.

And use EmuVariableUefi-64.efi driver with clover.
Now webdriver will load.

With Clover 3599 i can boot X99, Clover 3602 boot to black screen.
Only AC1150 don't work.

@SammlerG isn't that just the same as setting -nvda_drv=1 in the boot flags?

same issue for me guys i have the OS working accept on gt640 it boots up and monitor goes to sleep.. and i tried the web drivers and the flag didnt work.. but nv_disable=1 works every time but no acceleration..

Given my card still works fine under 10.11, I'll hazard a guess and say there's a bug in the latest web drivers?

Thanx jimmydigital100 and SammlerG, but nothing helped.

Strange, because I have not had this problem with many previous OS X updates.

I am using latest web drivers.

Everything else works OK.

So, here's how I got it "working":
After installing the driver, you'll reboot as if you were using El Capitan.
Then, add the boot-flag: nv_disable=1 (Just for now), and boot.

After booting, open terminal and type: nvram nvda_drv
Then check if it returns: nvda_drv 1 (It must be 1)
If it doesn't, then, you'll need to set it, using: sudo nvram nvda_drv=1)

Now, restart your pc and check if it works. If you get a blank screen (no signal), after 2º boot stage, that's probably because you have 2 monitors OR you're using a DVI connector. Try changing the connector/unpluging one of the monitors.

I didn't figure out how to get multiple monitors working, yet.
About nvram, seems like nvidia drivers aren't recognizing nvda_drv as a boot-flag, anymore.
Also, check if your system saves nvram after reboot, if it doesn't, then, you'll need EmuVariableUefi driver.

As Macsofrido says, this is the way to go too for my setup with 2 GTX 970.

With a "nvram -p" in terminal I get this:

nvda_drv    1
EmuVariableUefiPresent    Yes

The NVRAM command is not persistent for me so I use EmuVariableUefi.

I can get multidisplay working on one card if I plug only one cable until I'm in Sierra. After that, both are working. But I plug one cable on each card (1 Display port & 1 HDMI) and everything is fine on start.. You "just" need 2 graphic cards for that

GPU acceleration does not work for me either on Gainward GeForce 450 GTS (after booting monitor goes to sleep). I tried also with built-in nvidia drivers but with no luck. Only way to boot is to use nv_disable=1 flag. Also I had to use iMac 12.2 definition, because iMac 14.2 gave me IOUSBHostFamily kernel panic. On other SSD El Capitan works without any issues (GPU accel. with web drivers) with iMac 12.2 definition.

Update:
I fixed blank screen by changing system definition back to iMac 14.2 and fixing USB KP by patching dsdt. Now GPU accel. is working with built-in nvidia drivers, but when using nvidia web drivers i have screen artefacts. For now I'm happy with built-in drivers and only thing that doesen't work is sound (ALC892).

Update2:
Fixed audio with latest audio_cloverALC-120 script from toleda.

I am using

• Clover 3625
• RC scripts installed
• persistent nvda_drv=1 in nvram
• Web Drivers b07
• System Definition iMac 12,1 and iMac 12,2 (Sandy Bridge System)
• GTX 750Ti, DVI

Sierra will only works when I add nv_disable=1. Works fine with El Capitan

Any ideas? Otherwise, I need to wait for PB2 it seems...

Try with iMac 14.2 or iMac 13.2 system definition.
