Fujifilm released their software to enable you to use mirrorless X-series cameras as a Mac webcam. Initially, the Fujifilm X Webcam was released in May for Windows computers and in midsummer of July, a Mac version was later released.
Fujifilm X Webcam operates with APS-C Mirrorless Models X-T200, X-A7, X-H1, X-Pro2, X-Pro3, X-T2 and X-T4, and three Medium Format Models GFX.
For Mac users, FujiFilm lists them only as Zoom-based, Team, Skype-based, and Meet-by-Chrome versions of Edge, so it might not be possible for you to use them with Safari.
FREE from Fujifilm 's website is available for download now.
