Apparently something's amiss with the hardware or implementation at Razer (who otherwise specializes in flashy, high-end Windows gaming peripherals) and the Kiyo webcam with built-in ring light is strictly indows ONLY. It isn't reported to work on Mac OSX, and as such is sadly the WRONG choice at this time for Macintosh users shopping for an external USB Mac compatible webcam.
The alternative is a rather pricey and high-end webcam / mic / ringlight / USB hub combo: Check out the Marantz Turret Pro Broadcaster instead which is worth a look-see if you're looking for a 1-piece audio - video conferencing / streaming webcam with ringlight that IS Mac OSX compatible.
The Go-To brand seems to be Amscope with good software support for Macintosh computers. Omax is another digital USB scope manufacturer worth checking out. Some are conventional computer lab microscopes for medical or biological uses that combine both optical eye-pieces plus a digital camera sensor for capturing and recording whatever it sees under high magnification. Windows users will likely find snapshot and video capture apps more readily available, but Linux and Mac OS users will find any general purpose still image or video capture program will let them capture images or video clips from the digital computer microscope's sensor.
There are also many MacOS friendly UVC compatible inspection microscopes for business, industrial, construction or hobbyist uses. Some are handheld such as dental cameras, some feature a mounting stand, others may have a long or extended cable for, say, automotive engine or in-wall construction inspections.
