Users who have the latest Mac OS X machine will find that Lion offers a number of nice changes and features, but perhaps the most noticeable are the improvements to OS X security and privacy protection. The new and improved applications feature a new look and feel, a new user interface, new widgets, a faster and more efficient desktop, and improved performance and security on the Mac. OS X Lion comes with many new and updated applications, a new Finder application, and has been designed to be faster and more stable than any previous release. Like all other major releases, this one also has some nifty features. OS X Lion is the latest release of Mac OS X, which is the seventh major version of OS X, designed primarily for the Apple Mac computer.
