Hey everyone
(and sorry for my poor English)
I just got a GT 720 with GK 208 core (which should be supported according to the buyer's guide).
And trying to use it to run on MacOS BigSur.
My current build is i7-10700k + Z590 vision G + GTX 980 Ti (for Win10) + GT 720 (for MacOS).

It turns out that I even lost the signal in BIOS stage.
And the remove of -wegnoegpu has no use to it.

I have a feeling that this have to do with some setup in BIOS, but I can actually boot into Win10 successfully with this card as primary display output. (the signal still lost in BIOS stage though)
How can I use it to run BigSur smoothly?

Ok
So when I unplug GTX 980ti from the MOBO
I can actually get the visual signal from GT720.
But the next problem now is, the Apple logo stuck in the half way of the progress bar.

In principle it should start without problems, because I think it has native support, like my nvidia 710. I would add in the config.plist the command:

-v

in the bootargs section of opencore, to see the log at startup and see where it stops.

Thanks for the info, I'll update on this when I'm able to work on it.

If you add -wegnoegpu to your config.plist you will disable both the GTX980 Ti and the GT720 because that boot argument disables ALL discrete GPUs.

You need to use a custom SSDT to disable just the GTX 980 Ti.
