The retail version costs a bit more but comes with a manufacturer warranty. Apple offers the upgrade free of charge to customers who purchase the most recent version of the Mac OS X and also provides free technical support for the first year. If you're looking to upgrade your Mac OS X machine, or just want to try out the latest version before switching to a different brand or model, you might want to consider upgrading to the latest version, which is available in both a free and a retail version. In addition, the Mac OS X Lion updates the Mac's security and privacy protection with various protection levels that can be configured individually, allowing users to choose the level of security they want to achieve. The new version boasts a built-in firewall that protects against these attacks, preventing unauthorized access to the Mac's files. With the previous operating system, Mac OS X was prone to being attacked from viruses and spyware. 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.
