Highlights from Apple’s Developers Conference

Apple announced these offerings and more during a keynote address Monday to open its Worldwide Developers Conference in San Francisco. Here are the highlights.

MAC UPDATES

Apple has traditionally named its Mac operating systems after big cats, such as 2012’s Mountain Lion. It’s running out of animals, so it will now pay homage to the geography of its home state. This fall, it will release Mavericks, named after an undersea rock formation that produces big waves near Half Moon Bay, Calif., not far from Apple’s headquarters in Cupertino.

The new operating system will support tagging to help you find files more easily. Simply assign one or more tags such as “important” or “movies” to a particular document as you save it.

Mavericks will also work better with multiple monitors, with docks and menus going across the various display screens. A TV connected via Apple’s AirPlay can serve as one of those displays.

The new system also promises better battery life.

An updated Safari Web browser will make it easier to bookmark favorite sites with just one click. Safari will also have a new scrolling feature. When you get to the end of an article on your list of links to read, it will automatically pull up the next item as you continue to scroll downward. There’s no need to stop what you’re doing to click on another link.

Through the iCloud online syncing service, you will be able to keep track of all your passwords – encrypted for security – across your various devices. And when you’re shopping, it will automatically suggest credit card numbers you’ve used in the past. You will still have to enter the security code on the back of your card, however.

Apple is bringing its mapping service to desktop and laptop computers, challenging Google Maps and others. The company introduced it on the iPhone last year. The Mac is also getting the iBooks app previously available on iPhones and iPads.

It’s the latest evidence that Apple’s software for mobile devices and traditional computers is converging. Still, Apple has said it prefers to keep the two separate because the Mac software is designed for non-touchscreen devices such as desktops and laptops.

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. The new MacBook Airs went on sale Monday: The 11-inch one starting at $999 and the 13-inch model starting at $1,099.

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 U.S.

MUSIC

Apple unveiled a streaming music service, 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 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. Apple said it will be free with ads, though subscribers of Apple’s $25-a-year iTunes Match service will get it ad-free. It will be available this fall in the U.S.

iWORK

Apple also announced a long-overdue upgrade to its iWork suite of productivity software. The new version will tap iCloud and let you run the programs from a Web browser, similar to Google Docs. The suite includes Pages for word processing and Numbers for spreadsheets.

The iWork package is cheaper than Microsoft’s Office, but has worked only on Apple devices. Because the new version works on a Web browser, you’ll be able to use it on a Windows computer, too. The last major upgrade to iWork came in 2009. The new edition is called iWork for iCloud and will be available this fall. Apple didn’t provide details on pricing.
