In addition, macam also supports downloading of images from some dual-mode cameras. macamespecially tries to support those cameras not supported by Apple or by theirmanufacturers. macam consist of an application and a component. Run the macam application to verifywhether your camera works with your Mac and your USB setup. The component is that actual driver that allows other applications to access thevideo-stream.
