Cook is under pressure to show that Apple is not slowing as deep-pocketed competitors like Samsung Electronics and Google Inc encroach on its market.

Apple's Senior Vice President Software Engineering Craig Federighi introduces OS X Mavericks operating system during WWDC 2013.

The new Mavericks operating system will support tagging to help you find files more easily. It will also work better with multiple monitors, with docks and menus going across the various display screens. The new system also promises better battery life.

The company also said a new Mac Pro will come this year. It will be assembled in the United States, consistent with Apple's previous pledge to move manufacturing of one of its existing lines of Mac computers to the US.

Apple announced battery-life improvements to its line of MacBook Airs, which are thinner and lighter than traditional laptops. The 11-inch model will have nine hours of battery life instead of five, while the 13-inch model will have 12 hours, instead of seven.

Apple announced the iOS 7, the next version of its operating system for iPhones, iPads and iPod Touches. The biggest change comes in the new system's design: Instead of app icons that try to mimic real-world counterparts, Apple is favoring simplicity and consistency from app to app.

Eddy Cue, Apple senior vice president of internet software and services, introduces iTunes Radio. The service will personalize listeners' music based on what they've listened to and what they've purchased on iTunes. If you like a song, you can buy it through iTunes with one click.

The iTunes Radio service will be built into iOS 7 and work on Apple's mobile devices. It will also work with Apple's iTunes software on Mac and Windows computers.
