Live Blog from Apple's WWDC 2013 SAN FRANCISCO - As expected, Apple shared details of the next version of its iOS mobile operating system during the opening keynote address at its annual developer conference. Speaking before an overflow audience here in the Moscone Center, Timothy D. Cook, Apple's chief executive, and other company officials ran through features of the new operating system, which will be available in the Fall. The company also unveiled a much-anticipated streaming radio service, as well as a updates to several apps. 3:16 P.M. And That's a Wrap Just to recap: Apple took the wraps off the next version of iOS 7, which has a very different look from earlier versions. When it hits consumers in the fall, it will come with a much-anticipated streaming music service. Apple also demonstrated a new version of its mapping service and other maps. Thanks for joining us. 3:06 P.M. A New Kill Switch3:04 P.M. IOS 7 Coming in the Fall ITunes Radio is included in iOS 7, which is available on iPhone for developers today, but for everyone else, a final release is coming this fall. One last feature coming with this update is called Activation Lock. It's supposed to help deter people from stealing your phone. People have to log into the phone before they can do anything with it. "We think this is going to be a great theft deterrent," says Mr. Federighi, who is now back on stage. Mr. Cook is back on stage closing up. "Our goal at Apple is to make products that customers love," Mr. Cook says. Really great products that enrich people's lives. He is talking about the products that have been announced today, and is now showing an ad that expresses how he feels about the company's products. "This is it; this is what matters," the voice on the ad is saying. The experience of the product, how it makes someone feel. Will it make life better? Does it deserve to exist? 2:56 P.M. Apple Unveils iTunes Radio Mr. Cue is showing a new version of the iOS App Store. There is now a way to search for apps based on location. More important, there is an updated music player that has the new feel, making album covers front and center. Mr. Cue just showed iTunes Radio, the long-rumored Apple music service. There are stations within iTunes Radio. It is also integrated with Twitter's new music service. Mr. Cue is playing Led Zeppelin from an iTunes Radio station. "Another great feature of iTunes Radio is that it keeps track of all the songs you're listening to across all your devices," he says. ITunes Radio works on an iPhone, iPad, Mac OS X iTunes application and even on the Apple TV. "It's free with ads; if you're an iTunes Match user, it is completely ad-free," Mr. Cue says. 2:49 P.M. Apple Updates Siri Eddy Cue is now on stage to talk about Siri. Mr. Cue is showing a new interface for Siri. It now has new voices; there is either a new female or a male voice that sounds more realistic. There are new commands in Siri, including, "Play my last voice mail," "Turn on Bluetooth" and "Increase my brightness." What if you could get iOS on the screen that is built into your car? Mr. Cue is asking the audience as he shows a car navigation system running Siri. In 2014, car manufacturers will be adding iOS to their cars, Mr. Cue says. Nick Bilton 2:46 P.M. Update to Apple Camera App The new Camera app has eliminated gradients. The camera also gives people built-in access to live photo filters. Photos are no longer just in a stream of images based on a timeline. Now there are "natural organizations" that Mr. Federighi says are organized into a feature called Moments. These Moments can be viewed based on locations. You can also zoom out into a year view, which shows tiny little icons of pictures that you can tap on to see a thumbnail. You can edit photos directly within the app using the new built-in filters feature. The new Photos app looks somewhat similar to Facebook's photo features. 2:40 P.M. A Different Design Influence We're seeing a demonstration of Safari, which is full screen, with new swipe features to navigate back and forth between windows. It looks very similar to the version in Mac OS X Mavericks. With the new tabs feature, you look at the tabs you have open in your browser, like peering down into a file cabinet. It's an unusual user interface for a small screen. You can see a switch in design influence here. The original version of iOS was designed by pulling elements of the Mac computer's operating system. Now, the new iOS 7 is pushing design elements to Mac OS X Mavericks. 2:32 P.M. Apple Digs Into iOS 7 Features Mr. Federighi is back up on stage to demonstrate all the new features of iOS 7. The background of the home screen has a slick, animation-style wallpaper. As you move the iPhone in your hand, it tracks your motion so you can see behind the icons. The felt, wood and any texture-like looks are completely gone from iOS. Messages still has bubbles for text, but any gradients are now completely gone. The entire experience, through all apps, now includes an edge-to-edge design, and has very thin typography that looks like a variation on Helvetica Neue Thin. "Installing iOS 7 on your phone is like getting an entirely new phone," Mr. Federighi says. There are new features, too. Control Center allows you to swipe up with your thumb on the bottom of the device and see your phone's settings, which include brightness and media controls. 2:26 P.M. So Far, Markets Are Unimpressed Apple's stock, which has swooned since this event last year, is up for the day, but has declined - so far - since the keynote event started. 2:24 P.M. Different, Flatter Look to iOS A video is playing of the new iOS 7, which is flat, clean and looks beautiful. "We have always thought of design of being so much more than the way something looks," the voice of Jonathan Ive is saying on the video. The new design uses very thin typography and a new color palette. The keys on the keyboard look very simple, with gray letters on flat, white backgrounds. The crowd is whistling and cheering at the iOS 7, which looks incredibly simple. Mr. Cook, now standing on stage, is smiling from ear to ear. 2:19 P.M. Apple Unveils iOS 7 Mr. Cook is back on stage. He's talking about iOS. "We have sold over 600 million iOS devices," Mr. Cook says. IPhone users use their iPhone 50 percent more than Android users use their phone. Mr. Cook says, showing a recent survey. "They love them more," Mr. Cook added of the iPhone in comparison to Android. Over 90 percent of iOS users are using the latest version of iOS, Mr. Cook says. For comparison, he's showing a slide on Android, which he calls a "pretty bleak story." He added: "More than a third of Android users are using an operating system that was released in 2010." "Today, it is a great thrill that I announce iOS 7," Mr. Cook says. He is showing a very flat logo with the number 7. 2:13 P.M. Updates to Apple's iCloud And Mr. Cook is back on stage. He's talking about iCloud, the company's cloud-based service. There are 300 million iCloud accounts, he says. ICloud has sent 800 billion iMessages and 7.4 trillion push notifications, Mr. Cook says. Roger Rosner, an Apple software manager, is on stage demonstrating the new iWork for iCloud, which will let you create documents in a Web browser on a Mac or PC. Pages in iWork for iCloud work directly within a Web browser and look exactly like apps on a desktop. You can change fonts, insert images and insert graphics, all using drag and drop from the desktop. Mr. Rosner is explaining that Pages for iCloud can edit Microsoft Word documents and Numbers for iCloud can edit Microsoft Excel files. "Again, this is all happening in a Web browser," he says. He is now showing iWork for iCloud running on a Windows computer. "There you go, I am editing a Keynote document on Windows 8," Mr. Rosner says. iWork for iCloud is available today for developers, but will be available for everyone else by the end of the year. (Correction: An earlier version of this live update misspelled the surname of an Apple software manager. He is Roger Rosner, not Rosener.) 2:07 P.M. MacBook Airs to Feature "Haswell" Processors The Times's Quentin Hardy wrote in April about the Haswell processor, as its producer, Intel, hoped to move beyond PCs. 2:04 P.M. Mac Pro: An Entirely New Computer "We're going to do something different," Mr. Schiller says. We'd like to give you a sneak peek of something we're working on. He's about to show a new product called the Mac Pro, which is an entirely newly designed computer. The room just dimmed, a video is playing with loud music. The new Mac Pro looks like a cylinder-shaped black computer. Mr. Schiller just cracked a joke using a curse word at people who said Apple couldn't innovate anymore, and the crowd erupted in cheers. Mr. Schiller is now rattling through a number of statistics about the new Mac Pro. He's throwing out numbers and gigabits and teraflops that most likely make no sense to normal people, but have the room oohing and aahing. Mr. Schiller is talking very quickly about the new Mac Pro. He's either really excited about the new computer or he has had too many cups of coffee this morning. "It's designed in California and assembled right here in the U.S.A.," Mr. Schiller says. 1:57 P.M. MacBook Air Updated It's hardware time. Phil Schiller, Apple's senior vice president for marketing, is now on stage, and immediately jumps into the MacBook Air. "We've updated an entirely new line of MacBook Airs," he says. The 11-inch MacBook Air will have nine hours of battery life; the 13-inch will have 12 hours of battery life. There is also a new Airport Extreme base station that comes with a wider range, and it comes with a built-in two- or three-terabyte hard drive. Prices for the new MacBook Airs: 11-inch with 128 gigabytes is $999, the 13-inch starts at $1,100. (Correction: An earlier version of this entry misstated the battery life Apple is citing for the 13-inch MacBook Air. It is 12 hours, not 11.) 1:51 P.M. Update to iBooks IBooks now works on the Mac, too. The background, which on iOS used to look like an old wooden bookshelf, is now a stark white. Book covers sit in the air. You can scroll through iBooks right on the Mac. There are also study cards for students using iBooks on the Mac. 1:49 P.M. Apple Maps Updates Maps is now available for the Mac OS X. At first blush, it looks clean and slick, and people can share map locations to their iOS devices. We're seeing a demo of Maps. The map is in Paris, it looks fast as it switches to "flyover" pictures of the Eiffel Tower. It shows stunning images as the app spins around. Mr. Federighi is pulling up directions in Maps on his Mac and is then sending them directly to his iPhone. Maps is also integrated into the new Calendar app and can show a projected time to get to the destination of an appointment. 1:44 P.M. Updates to Calendar Next up, Calendar. It looks flatter and much cleaner than the previous version. "Absolutely no virtual cows were harmed during the making of Calendar," Mr. Federighi says. 1:40 P.M. Strong Response to Federighi As Craig Federighi, Apple's senior vice president for software engineering, explained updates to the new operating system and the Safari browser, among other new features, his affability and humor drew admiration from Twitter users. Some even wondered if Mr. Federighi would be someone the public would get to know better in the future. 1:41 P.M. Updates to Safari Browser Mr. Federighi is now moving into the Safari Web browser. There is a sidebar within the app that can give you access to all of your bookmarks and reading lists, and "a new feature called shared links, where you see all of the links shared by people you're following on Twitter and LinkedIn." No love for Facebook, though. Mr. Federighi shows slides that say Safari is the fastest browser available today. "When compared to Firefox," he says, "it's just kind of sad." He moves on to more in-depth demos of Safari, showing how the new bookmarks and shared links features work. A new feature called iCloud Keychain is built into Safari, to remember your Web site logins, passwords and credit card numbers. It can even auto-suggest a new password for Web sites. It looks very similar to the password application 1Password. 1:34 P.M. Mavericks Reduces Power Consumption Mavericks includes new smart technologies that can reduce power consumption on the processor by 72 percent. There is also a new feature called "compressed memory," which can speed up a Mac. 1:29 P.M. More Details on Mavericks Next up, multiple displays. "In Mavericks, you can get your menus and summon your dock across multiple displays," Mr. Federighi says. We're now seeing demos of tagging and a full-screen finder experience, which is how you understand where your files are on your computer. The overall user interface looks the same. And we're also seeing a more in-depth demonstration of Tags, full-screen displays and multiple screens. They are providing an Apple TV demonstration, where a Mac computer is connected using Airplay, and is displaying the contents and apps. Say goodbye to traditional projectors. 1:22 P.M. Mac OS Update: A New Theme And we're about to see an update to OS X. Craig Federighi, Apple's senior vice president for software, is on stage. He's kidding around about Apple running out of cats to name its OS after, and suggested Mac OS X Sea Lion, then laughs. The new OS X will have a California-themed release. The new OS X will be called OS X Mavericks after the biggest surf spot in California. The waves at Mavericks are sometimes as high as 40 feet, and it's home to a famous surf contest. OS X is going to introduce "Tags" to the Mac. When a document is saved, in addition to providing its location and name, it will appear in the sidebar of a finder under the tag name. 1:20 P.M. Mr. Cook Provides Mac Update Next up, the Mac. We announced the new iMac at the end of last year and it went on to become the No. 1 desktop in the U.S.," he says. The Mac sales are up 100 percent, versus, as Mr. Cook calls it, "a paltry" 18 percent for the rest of the PC market. "Thirty-five percent of Apple's users are using Mountain Lion," Mr. Cook says. 1:13 P.M. Mr. Cook Is Joined by Toy Cars "We have now paid developers $10 billion" through the App Store, Mr. Cook says. "That's three times more than all other platforms, combined," he adds, showing a graph of iOS versus Android. There is now a demo by Anki, a new company that integrates iOS with physical toys. Boris Sofman, the company's co-founder, explains that the company began as a robotics idea from a lab. There are cars steering around a physical toy car track using an iOS app on an iPhone. There are a lot of "oooohs" from the audience. "We are using iOS devices not just as a remote control, but as the brains behind an immersive experience," Mr. Sofman says, as four cars spin around on a toy track. 1:12 P.M. A New iOS Developer1:09 P.M. Update on Retail Business Mr. Cook gives an update on Apple's retail stores. They get one million daily visitors a day. Tens of thousands of schoolchildren pick their local Apple store as the destination for their annual field trip. Millions of customers come to stores for personal training. There are 407 stores in 14 countries. A new store was opened in Berlin. Now Apple is showing a video about the opening of the Berlin store. "We also have some pretty great digital stores," Mr. Cook says, noting that the App Store is going to celebrate its fifth birthday next month. Customers have now downloaded 50 billion apps from the Apple iTunes store. The company now has 900,000 apps in the store, 375,000 apps that have been designed for iPads, and 575 million accounts. "We have now paid developers $10 billion," through the App Store, Mr. Cook says. 1:06 P.M. Mr. Cook Addresses Attendance "Those words mean a great deal to us," Mr. Cook says. Welcome to the Worldwide Developers Conference. The crowd is cheering and clapping. Mr. Cook is talking about the company's developer program. Apple sold out tickets to WWDC in 71 seconds, Mr. Cook says. 1:04 P.M. Timothy Cook Takes Stage And we're beginning. There's an ad for Apple design, asking, "How can anyone perfect anything?" then showing a series of quotes about simplicity and design. As the ad concludes, touting Apple's design, Timothy D. Cook, Apple's chief executive, walks out on stage. 12:29 P.M. Crowd Filing Into Moscone Center We're finally seated in the auditorium. The song "Let's Go," by Matt & Kim, is playing on the loudspeakers as thousands of people are rushing to grab their seats. In the hallway outside some large billboards are shrouded in black cloth, presumably hiding some of the new products we will see when the Apple event begins in 30 minutes.
