I am trying to add a new signature to a document in Preview, but when I click on "Create Signature" to use the webcam attached, it instead wants to use the virtual camera defined in OBS, which is not even currently running. I imagine that I could go into OBS and hook up the camera and enable the virtual camera feed, but...
Can't I just select the camera I want to use in Preview? I don't see a way to do that.
