Most common Macs will require a DVI or Mini DisplayPort adapter from Apple.
Cinemin Swivel is a recreational multimedia pico projector - designed primarily to connect to iPhones, iPods, and composite video-out devices to project videos and photos. Please be aware that computer connectivity requires an additional adapter (specific to your computer's video output), that small-text and detailed spreadsheets will be difficult to read at HVGA resolution, and that as with all pico projectors low-light conditions are needed for optimal visibility.
