The snap virtual camera is not working on OSX 12.1.1 or 12.2.1.
It simply does not appear in the list of options when running multiple applications either natively (apple silicon) or using Rosetta 2 (emulating Intel).
Does not appear system wide. I've tested, Zoom, Quicktime Player, VDMX, OBS, MadMapper Google Meet, Skype, etc.
OBS Virtual Camera, and Logitechs LOGI emulated camera both work on this system.
Support, says v1.18.0 is the latest version of Snap Camera.
Filters work in the snap camera app using Facetime Web camera, but this application does not share it system wide. If the developers cannot figure this out, they should at least implement syphon to share with other applications.
