nVidia Divers support macOS Catalina ?

[wyatt-wong]

Does this nVidia Drivers support macOS Catalina ? I got the following errors when I download and install the drivers.

[algol68]

1 - disable SIP
restart in recovery mode
type csrutil disable
2 - disable Gatekeeper
back in 'normal' mode open Terminal and type sudo spctl --master-disable
3 - remount file system (enable write mode of system volume)
sudo mount -uw /
4 - force Finder process to restart
killall Finder

you should be able to install nvidia drivers now ;-)

This works, can probably close this issue now. Thanks!!

Can we enable SIP after finish install the display drives in Catalina ?

Just to clarify, nVidia's drivers do not work on Catalina (or Mojave for that matter).

Yes, they'll install, and that may allow you to set some different screen resolutions, however macOS will not be hardware accelerated.

There's been a lot of coverage on this issue, so a quick Google will explain what's going on. It's for Apple and nVidia to sort out; which they likely won't.

Well even without hardware acceleration, we can at least install the display drivers for Catalina Sent from my iPhone 11 Pro Max On 26 Mar 2020, at 2:22 PM, Benjamin Dobell <[email protected]> wrote:  Just to clarify, nVidia's drivers do not work on Catalina (or Mojave for that matter).

agreed. workaround gets you past installation errors however drivers really don't perform as they should. @Benjamin-Dobell, i think noting this on the project homepage will be helpful (don't upgrade past High Sierra)

@Benjamin-Dobell
Do you think there is any hope for Big Sur?

There is ZERO hope for Big Sur or any iteration of Apple Software when it comes to Nvidia. It's ridiculous, but it is what it is. Redshift is coming to Apple Metal. Octane X is already out. And so on and so forth.

@23d1
The latest I can go with the @Benjamin-Dobell 's drivers is High Sierra?

• Pimped a MacPro 3,1 with a nvidia 980Ti (6GB VRAM) and macOS Catalina. Connected it to the Samsung C49HGx 32:9 4K Monitor and got it to work like this:

• Connected the Monitor with HDMI and 1920x1080@144Hz

• Used the tipps from @algol68 (disable SIP, disable Gatekeeper, remounted root with -uw...)

• Ran Benjamins script to install the nvidia drivers.

• Important: after reboot, set the screen refresh rate to 60Hz, so higher resolutions are available.

• Installed the Resolution Helper Tool SwitchResX and defined a 3840x1080@60Hz resolution.

• Activated the resolution and voilà! Got it running...

Update:
If you create a custom resolution 3840x1080@100Hz this will also work. If your screen turns black after login, here is a fix:

• Activate screensharing BEFORE you switch the appscreen resolution
• connect by ssh from another host and become root
• delete the nvram variable nvda_drv, which is set to 1%00
• reboot your MacPro

Acceleration in macOS is not so important for me, I need the widescreen resolution for working - for gaming I reboot my MacPro 3,1 to Windows 10 Pro 20H2...
