OBS with Zoom via a USB3.0 Capture card in Mc OS Catalina

[Topanga Mac]

I just installed OBS Studio V 25.0.8 (64 bit) on my Mac Mini using a USB3.0 HD Video Capture card and it works well inside of OBS Studio. When I try to configure Zoom video to OBS, Zoom only shows "USB3.0 HD Video Capture" instead of "OBS" as a camera and does not connect to my camera, a Nikon D7200. Is there a driver that I need to install on my Mac? Many thanks.

You need OBS virtual cam. Set it to auto-start in OBS so it's always available as a camera source to Zoom. I'm only using it on Windows (works great) but there is a Mac version as well. https://github.com/johnboiles/obs-mac-virtualcam
