Apple OS X Lion is built on a rock-solid UNIX foundation, engineered to take full advantage of the technologies in every new Mac, and designed to deliver the most intuitive and integrated computer experience possible.
Hardware and software made for each other. Since the software on every Mac is created by the same company that makes the Mac, you get a fully integrated system in which everything works together perfectly. OS X works with the processor architecture in your Mac to deliver the best possible performance. Mac notebooks include a Multi-Touch trackpad that lets you pinch, swipe, and tap your way through every app on the system. OS X gives you long battery life by dimming the screen in low-light conditions and even regulating processor activity between keystrokes.
Easy to use and incredibly powerful. From the desktop you see when you start up your Mac to the applications you use every day, everything is designed with simplicity and elegance in mind. So getting things done is both intuitive and fun. Of course, making amazing things simple takes seriously advanced technologies, and 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.
Secure by design. OS X doesn't get PC viruses. And with virtually no effort on your part, the operating system protects itself from other malicious applications. Because every Mac ships with a secure configuration, you don't have to worry about changing complex settings in order to stay safe. Even better, OS X won't slow you down with constant security alerts and sweeps. Apple responds quickly to online threats and automatically delivers security updates. And with FileVault 2 in OS X Lion, all the data on your Mac is protected by powerful encryption.
Built for compatibility. The versatility and power of OS X help a Mac fit in just about anywhere--including Windows networks. Want to transfer your files, photos, and other data from a Windows PC? OS X lets you do that easily. If you want to run Windows on your Mac, you can do that, too. OS X has built-in support for the latest version of Microsoft Exchange Server, so you can use your Mac at home and at work and keep all your messages, meetings, and contacts in one place. OS X works with virtually all of today's digital cameras, printers, and other peripherals without the need to manually download separate drivers. And it opens popular file types such as JPG, MP3, and PDF, as well as Microsoft Word, Excel, and PowerPoint documents.
Accessible innovation. OS X comes standard with a wide range of assistive technologies that help people with disabilities experience what the Mac has to offer, including many features you won't find in other operating systems
This update is recommended for all OS X Lion users and includes general operating system fixes that improve the stability, compatibility and security of your Mac. It also includes Gatekeeper, a new security feature that helps you keep your Mac safe from malicious software by giving you more control over what apps are installed on your Mac.
