OS X Mavericks. The next big release of the world’s most advanced desktop operating system. Coming this fall.

Safari

Easily get to the places you go most. And will want to go next.

Safari in OS X Mavericks delivers blazing performance and introduces breakthrough technologies. Innovative features make it simple to return to sites you visit often — and discover new sites as well. Shared Links in the new Sidebar shows links posted by people you follow on Twitter and LinkedIn, so you can keep up with the latest interesting content. And with the redesigned Top Sites, it’s easy to organize your favorites. There are also unique advancements under the hood. Thanks to the new Nitro Tiered JIT and Fast Start technologies in Safari, the web pages you visit feel snappier and more responsive. Browsing the web can take a toll on battery life, but with new power-saving technologies, you won’t waste energy on web pages in the background or plug-in content you don’t want to see. In OS X Mavericks, Safari is simply the best way to surf.

Finder

One window. Multiple tabs.

Finder Tabs help you declutter your desktop by consolidating multiple Finder windows into one. You could keep a tab for Documents, one for AirDrop, and one for Back to My Mac, all in a single Finder window. You can switch between tabs, customize views, and reorder them however you like. To move a file from tab to tab, just drag and drop. And now you can even expand a Finder window to full screen and effortlessly move files wherever you want.

OS X Server

More control for you. Easier collaboration for all.

OS X Server includes a number of innovations that will help the people who use your network as well as the people who manage it. The new features in Xcode Server make it easier than ever for a Mac or iOS development team to create robust, reliable software, thanks to continuous integration, testing, and repository hosting services. Caching Server 2 speeds up the download and delivery of software through the App Store, Mac App Store, and iTunes Store, and it can now cache on your server for faster downloading to iOS 7 devices. And Profile Manager has an array of new management features for iOS 7 and OS X Mavericks that simplify software distribution of apps and books.

Advanced Technology

The most powerful OS X ever is also the most power efficient.

With OS X Mavericks, your Mac works even smarter. Energy-saving technologies help you get more out of your battery, and performance-boosting technology brings you more speed and responsiveness. It’s power wielded wisely. Learn more
