A:Answer You can use it with Zoom on a Mac. You have to download the webcam utility from the Nikon website first (see article on AppleInsider: "You can now use a Nikon mirrorless or DSLR camera as a webcam on Mac" from September 2020). My experience is that it barely made it through an hour meeting before running out of battery, even though it is plugged in to the computer via the included USB cable. It's also kind of buggy. I haven't done any trouble shooting on this issue yet. Otherwise, the Z50 video looks way better than then built in webcam.
