From now on digital cameras from FujiFilm can be used as webcams on the Mac. To do so, you will need this software, published by FujiFilm for the Mac and a mirrorless digital camera model. A list of currently supported cameras can be found here.
Now Mac users are able to replace the bad internal webcam of Macs with an existing Fuji camera. This not only offers a bad resolution but also a color range that is a real imposition depending on the MacBook model in 2020. It would be nice if Apple would use a better internal model, especially since a lot of things are shifting to home office and video conferencing.
But until then you can now use an external camera for important video conferences where quality is important. Other manufacturers already offer this option or are working on it.
