Mac and Windows operating systems treat Universal Video Class (UVC) webcams differently. UVC "plug and play" drivers started getting support on Windows platforms in OS XP SP2 and on MAC OS 10.4.11.
The tables below compare OS support for the various webcam controls and features one by one.

Current versions of MAC OS X don't expose the webcam controls listed above on a global-application basis. With some restrictions, webcam controls for a proprietary application (ex. Logitech Webcam Software) could be implemented, whereas it isn't possible to make these controls available for applications such as Skype or QuickTime.
