How to disable NVIDIA graphics card (10.13)

[VladislavHD]

Because of worst NVIDIA driver animation performance in High Sierra I decided to use integrated graphics (Intel HD530). But I still need NVIDIA card installed because I need Windows for games. Without NVIDIA card everything works OK, even sleep. With NVIDIA card I faced with some problems.
Hackintosh doesn't boot without NVIDIA driver installed. It stucks in some sort of loop. In verbose mode I see message `IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0`, then it quickly flashes `PEGP-A newUserClient failed: 0xe00002cd` and just keeps repeating that. I installed driver and now my hackintosh boots but with nvidia driver it becomes more painful to update macOS.
And sleep doesn't work. This is very important for me.
So I decided to find a way somehow disable NVIDIA card. I tried do this by editing SSDT/DSDT, but all information I found is about laptops. Does anybody know how to do this through SSDT/DSDT or maybe there is way by patching some kexts?

Thanks in advance.

Hi, did you resolve it? I have same requirements with you because there is no nvidia web driver for 10.14.

Yes, I resolved it. Unfortunately, I don't remember what I did exactly. Most likely I modified \SB.PCI0.PEG0._DSM method from PegSsdt table. Probably I applied this patch to this method https://github.com/jardenliu/dsdt-hotpatch/blob/master/common/SSDT-DiscreteSpoof.dsl. I uploaded the patched SSDT.

But I don't use this SSDT anymore since I got a vega card.

@VladislavHD
thanks Vladislav, I tried this script, but it doesn't work for me, the script only removed Nvida Card from "System report>Graphics/Displays, but unfortunately don't remove card completely because card fans still spinning so maybe I did something wrong, I just looking for a way to completely disable the NVidia card (GTX 980 ti G1) on a regular desktop PC but NOT ON LAPTOP
Can someone provide working info/patch for this

@MAC_OS Did you solve the problem? Need to do same

Yes, just install latest patched Nvidia Drivers, and then put appropriate commands in Terminal

sudo chmod -R 755 /Library/Extensions/NVDAStartupWeb.kext
sudo chown -R root:wheel /Library/Extensions/NVDAStartupWeb.kext
sudo touch /System/Library/Extensions/ && sudo kextcache -u /
sudo touch /Library/Extensions && sudo kextcache -u /
Restart your computer.

And don't use on Clover -wegnoegpu by boot>Arguments that's work for me!

Hi, I would like to do the same thing, but I don't get why you would have to download the latest Nvidia driver in order to do so ?

Could you please explain what you did and if it's working well now ?

Best,

Sorry m8, I no longer use my external graphics card, but I do remember that it worked with Mojave this way.
So, just try simply install latest patched Nvidia Drivers and then put all commands in Terminal which I posted above.
Good luck!
