Apple announces new MacBooks, operating system

A new OS called Maverick, an improved Safari Web browser and a MacBook Pro that's assembled in the U.S. are just some of the announcements from Apple today.

SAN FRANCISCO — Apple announced new MacBooks, a new Mac operating system and an update to its iWork package of productivity software during a keynote presentation Monday at the company's annual conference for software developers in San Francisco. It is also expected to reveal a digital radio service and changes to the software behind iPhones and iPads.

Apple is expected to show off a simplified look on iPhones and iPads. It would be the most radical design change since the iPhone made its debut in 2007. While design modifications could help Apple distinguish its devices from rival phones and tablets, they risk alienating longtime users.

For instance, Apple riled users of its gadgets last fall when it kicked out a beloved app using Google's mapping service and replaced it with its own Maps app. What was supposed to be a triumph for Apple served to underscore Google's strength in maps.

Apple may use an expected software update this fall, iOS 7, as an opportunity to update its Maps app. Other features in iOS 7 may include new ways to do things through gesture commands.

Apple is also expected to debut a streaming music service dubbed iRadio.

The keynote kicked off at about 10 a.m. PDT. Apple's Worldwide Developers Conference goes through Friday.

Apple unveils a long-overdue upgrade to its iWork suite of productivity software. The new version will tap Apple's iCloud online syncing service and will let users run the programs from a Web browser.

The current version dates back to 2009. The suite includes Pages for word processing and Numbers for spreadsheets. It's cheaper than Microsoft Office, but has worked only on Apple devices. Because the new version works on a Web browser, users can now use it on a Windows computer, too.

Apple shows a video previewing an upcoming MacBook Pro. It promises faster connectivity through Thunderbolt 2 ports and better graphics performance.

It will be available later this year and 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.

Apple announces new MacBook Airs with better battery life. 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 start shipping Monday, with the 11-inch model starting at $999 and the 13-inch model starting at $1,099. The Airs are thinner and lighter than traditional laptops.

Federighi says the Maps team has been making improvements to the service, which had been panned when it came out last fall. Users can search for directions on a Mac and have it sent to the iPhone, for instance. Apple will be competing with Google Maps, Microsoft's Bing and others on desktop and laptop computers. Apple's Maps app currently is available only on Apple's mobile devices.

The Mac is also getting the iBooks app previously available on iPhones and iPads. It's the latest evidence of Apple's software for mobile devices and traditional computers converging, although Apple has said it prefers to keep the two separate because the Mac software is designed for non-touch devices such as desktops and laptops.

The new Mac operating software will be out this fall.

Federighi unveils improvement in the Safari Web browser coming in the next version of Apple's Mac operating system. He demonstrates Apple's power-saving technology while browsing and announces one-click bookmarking. There's also an infinite scrolling feature — when users get to the end of an article, it will simply go to the next one as they scroll downward.

Need help remembering all your website passwords? Apple has a new feature on its iCloud file-storage service that keeps track of passwords — encrypted for security — across 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 the card, though.

Apple has had a practice of naming Mac operating system updates after cats, but Federighi worries the company is running out of names. After joking that Apple will call the next one Sea Lion, Federighi says the next will actually be called Mavericks, a reference to a big wave area in the San Francisco area.

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 with multiple monitors, with docks and menus going across the various display screens. TVs connected via Apple's AirPlay can serve as one of those displays.

The new system also promises better battery life.

Cook opens the keynote by talking about the status of Apple's more than 400 retail stores worldwide. He says Apple's newest store is in Berlin, in a century-old building that was one of the city's first theaters.

He also touts Apple's online store and says the company has 900,000 apps there, including 375,000 specifically designed for the iPad.

Cook walks on stage to applause from an audience of software developers and other Apple fans.
