We want all Mac users to experience the latest features, the most advanced technologies, and the strongest security. And now they can. Because the newest version of OS X is free. It’s a simple download from the Mac App Store, so it couldn't be easier to get. OS X Mavericks is another major leap forward for the Mac — and for everyone who uses it.
The Mac operating system is designed to be easy to use and engineered to take full advantage of the technologies built into every computer we make. So everything works just the way you expect it to. OS X also comes with powerful apps for browsing the web, sending messages, setting reminders, and so much more. And the apps work great with iPhone, iPad, and iPod touch, too.
OS X is built to bring out the best in your Mac, so you get a fully integrated system in which everything works together seamlessly. It works with the processor in your Mac to deliver the best possible performance. It works with the super-responsive trackpad in Mac notebooks so Multi-Touch gestures feel natural to use. Technologies like Power Nap take advantage of the Mac hardware to keep the entire system up to date while it sleeps.1 OS X gives you long battery life with advanced power-saving technologies like Timer Coalescing and App Nap. And it's optimized for the high-resolution Retina display in the high-performance MacBook Pro.
1. Power Nap requires a MacBook Air (late 2010 or newer), MacBook Pro with Retina display, iMac (late 2012 or newer), or Mac Pro (late 2013 or newer). May require a firmware update.
