Mac OS X. It's what makes a Mac a Mac.

Power of UNIX. Simplicity of the Mac.
Mac OS X is both easy to use and incredibly powerful. Everything--from the desktop you see when you start up your Mac to the applications you use every day--is designed with simplicity and elegance in mind. So whether you're browsing the web,
checking your email, or video chatting with a friend on another continent, getting things done is at once easy to learn, simple to perform, and fun to do. Of course, making amazing things simple takes seriously advanced technology. Which is why Mac OS X is built on a rock-solid, time-tested UNIX foundation that provides unparalleled stability as well as industry-leading support for Internet standards.

Stunning graphics.
The most striking feature of a Mac is its elegant user interface, made possible by a graphics engine that's built to leverage the advanced graphics processor in every Mac. This engine provides the power for things like high-definition video, stunning graphic effects, and high-quality animations. Fonts on the screen look beautiful and extremely readable. A soft drop shadow makes it clear at a glance which window is active and which ones are in the background. Document previews using Quick Look are high resolution so you can actually read the text. And built-in support for the PDF format means you can view and create PDFs from almost any application in the system.

Perfect integration of hardware and software.
Since the software on every Mac is created by the same company that makes the Mac itself, you get a completely integrated system. When you have a Mac notebook, for example, it automatically detects and connects to available Wi-Fi networks. It wakes from sleep as soon as you open the display and automatically reconnects to networks so you can get back to work fast. And it gets the most out of your battery by spinning down the hard drive when it's inactive, by intelligently deciding whether the CPU or GPU is best suited to perform a task, and by dimming the screen in low-light conditions.
Dock + Finder
The Dock in Mac OS X provides fast, one-click access to frequently used applications, folders, and even downloads from the Internet. The Finder makes working with your files and documents as easy as browsing your iTunes library.

Introducing the Finder.
The Finder is like home base for your Mac. Represented by the blue icon with the smiling face, it's one of the first things you see when you start working on your Mac. It lets you organize, view, and access practically everything on your Mac, including applications, files, folders, discs, and shared drives on your network.

Time Machine
Never again worry about losing your digital files. Time Machine automatically saves up-to-date copies of everything on your Mac--photos, music, videos, documents, applications, and settings. If you ever have the need, you can easily go back in time to recover anything.

More Power to Your Mac.
Since 2001, the breakthrough technologies and rock-solid UNIX foundation of Mac OS X have made it not only the world's most advanced operating system but also extremely secure, compatible, and easy to use. Snow Leopard continues this innovation by incorporating new technologies that offer immediate improvements while also smartly setting it up for the future.
