Mac OS X 10.6 Snow Leopard

Mac OS X is the world's most advanced operating system. Built on a rock-solid UNIX foundation and designed to be simple and intuitive, it's what makes the Mac innovative, highly secure, compatible, and easy to use. Quite simply there is nothing else like it.
 
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 technologies, and Mac OS X is loaded with them. Not only is it built on a rock-solid, time-tested UNIX foundation that provides unparalleled stability, it also delivers incredible performance, stunning graphics, and industry-leading support for Internet standards.
 
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 an integrated system in which everything works together perfectly. The advanced technologies in the operating system take full advantage of the 64-bit, multicore processors and GPUs to deliver the greatest possible performance. The built-in iSight camera works seamlessly with the iChat software so you can start a video chat with a click. Your Mac notebook includes a Multi-Touch trackpad that supports pinching, swiping, and other gestures. And the OS communicates with the hardware to deliver incredible battery life by spinning down the hard drive when it's inactive, by intelligently deciding whether the CPU or GPU is best for a task, and by automatically dimming the screen in low-light conditions.
 
Elegant interface and stunning graphics
The most striking feature of a Mac is its elegant user interface, made possible by graphics technologies that are built to leverage the advanced graphics processor in your Mac. These technologies provide the power for things like multiway chatting, real-time reflections, and smooth 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. You can preview just about any type of file using Quick Look, and because the previews are high resolution, you can actually read the text. Built-in support for the PDF format means you can view or create PDFs from almost any application in the system.
 
Highly secure by design
Mac OS X doesn't get PC viruses. And with virtually no effort on your part, Mac OS X protects itself from other malicious applications. It was built for the Internet in the Internet age, offering a variety of sophisticated technologies that help keep you safe from online threats. Because every Mac ships with a secure configuration, you don't have to worry about understanding complex settings. Even better, it won't slow you down with constant security alerts and sweeps. And Apple responds quickly to online threats and automatically delivers security updates directly to your Mac.
 
Built for compatibility
The versatility and power of Mac OS X make it compatible in almost any environment, including Windows networks. It works with virtually all of today's digital cameras, printers, and other peripherals without the need to manually download separate drivers. It opens popular file types such as JPG, MP3, and Microsoft Word, Excel, and PowerPoint documents. In addition, Mac OS X includes built-in support for the industry-standard PDF format, so you can read and create PDFs from almost any application in the system--perfect for sharing work with colleagues whether they use a Mac or a PC. If you want to run Windows on your Mac, you can do that, too. And Mac OS X Snow Leopard is the only operating system with built-in support for the latest version of Microsoft Exchange Server, so you can use your Mac at home and at work and have all your messages, meetings, and contacts in one place.
 
Reliable to the core
The core of Mac OS X is built on the same ultrareliable UNIX foundation that powers industrial-strength servers, helping to ensure that your computing experience remains free from system crashes and compromised performance. Even upgrading your Mac to the next version of Mac OS X is reliable and easy. It checks your applications to make sure they're compatible and sets aside any programs known to be incompatible. If a power outage interrupts your installation, it can start again without losing any data. Best of all, upgrading doesn't require reformatting your drive; you can keep all your compatible applications, files, and settings. And if something goes wrong when you're using your Mac, Time Machine is there to keep automatic backups of everything on your drive.
