UVC compatibility was an important development for the Mac compatible webcam market. With UVC drivers built into OSX 10.4 and up, custom Mac OSX webcam drivers (of which few even existed) no longer needed to be installed for the camera hardware to be recognized. 'They Just Worked' by plugging them into a USB 2.0 or faster port. UVC eventually became the DEFACTO standard preferred for web cameras on all personal computing platforms: Mac OS, Windows, as well as Linux.
