NVIDIA GeForce GT 120 512 MB not recognized after Catalina upgrade!

I was able to run SketchUp 2021 under Mojave (MacOS 10.14). I just upgraded to Catalina (10.15.7) and I get the following when I try to run SketchUp:

The following errors were found when launching SketchUp: - Hardware acceleration is unsupported or has been disabled on your “Apple Software Renderer” graphics card. SketchUp requires that you use a hardware accelerated graphics card. Unfortunately, these errors will prevent SketchUp from running. Updating your graphics card drivers might fix the problem. See this Help Center article for more information.

I have a NVIDIA GeForce GT 120 video card, and it appears to be functioning, as normal graphics-intensive things (like “genie effect”) is very zippy. System Preferences —> Software Update offers no help, and says I am up to date.

The link above says SketchUp requires OpenGL 3.0. System Information —> Frameworks says I am running “OpenGL Version: 17.10.22,” which doesn’t sound useful.

Any ideas as to what to try to get SketchUp to work?


I did some Google searching for ‘Nvidia GT120 Mac 10.15’ and came acros this thread. When will the Nvidia Drivers be released for macOS 10.15 Catalina? - #46 by sandra-leigh - Drivers - Linux, Windows, MacOS - NVIDIA Developer Forums

Scanning the thread seems to indicate that Apple changed the way drivers function in 10.15 and Nvidia drivers/cards no longer work …. Nor will they ever as there isn’t and won’t be new drivers from Apple.

Apple and Nvidia fell out many years ago so I was surprised your card even worked in 10.14, the GT120 is a circa 2009 card, that’s ~13 years old … not a bad run at all.
