Mac OS X Leopard   Mac OS X v10.5 Leopard features a stunning new look across the entire system including a sleek new Dock with Stacks, a simple way to quickly organize and access your files. You can use Cover Flow to see your files in the Finder and browse through them like you browse through album art in iTunes. Quick Look gives you instant, full size previews of your documents, images and movies without opening an application. And Time Machine provides an effortless way to automatically backup everything on your Mac. These innovations plus Spaces, Boot Camp and major enhancements to Mail and iChat, make Leopard and its more than 300 new features the richest release of Mac OS X yet.
