Apple revealed to the public yesterday at the fall event the new OS X Mavericks release. Four months after introducing the newest operating system for the MacBooks in their Worldwide Developers Conference last June, the company finally announced that starting today the new OS will be pre-installed in the new line of laptops and it will be free of charge.

The new updates are packed with as many as 200 new features. Included is the integration of iBooks and Maps to the laptops and the newest version of the web bowser Safari.

"Mavericks is an incredible release, which introduces significant new apps and features, while also improving the performance and battery life of your Mac," Apple's senior vice president of Software Engineering Craig Federighi said. "We want every Mac user to experience the latest features, the most advanced technologies, and the strongest security. We believe the best way to do this is to begin a new era of personal computing software where OS upgrades are free."
