Same expect according to Fuji, it's supposed to work on my version of OXS (Mojave). Installed the latest version of X Webcam 2, did a firmware update on X-T30, changed the USB connection setting to USB Webcam, connected the camera through USB (no hub).
The camera is not recognized and doesn't show up under available cams. Also, Fuji X Webcam software's entire interface is grayed out.
