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.

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.

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.
