Apple’s WWDC 2013 keynote event will go live today at the Moscone West convention center in San Francisco. Tim Cook, Apple’s CEO, will kick off the event with a keynote presentation at 10 AM Pacific Time.

At this years Worldwide Developers Conference Apple will unveil iOS 7 and the next major release for OS X. A live video stream of the keynote event will be available at Apple’s website and requires Safari 4 or later on Mac OS X v10.6 or later; Safari on iOS 4.2 or later. The company has added a new section for streaming via Apple TV and requires second- or third-generation Apple TV with software 5.0.2 or later to stream the event.

iOS 7 will be the first release that has been developed under the leadership of Jony Ive, SVP of Industrial Design, as Apple fired Scott Forstall allegedly over Apple maps fiasco and an internal divide over the skeuomorphic design elements. In addition to a redesign iOS 7 is expected to open new API’s for developers giving more control over features and could also introduce AirDrop for iOS to make sharing between iOS devices easier.

No details have been available about what’s new in OS X. Apple usually previews new version of OS X earlier in the year however, it is believed that the company had to pull engineers from OS X team to work on iOS 7.

Banners for iOS 7 and OS X suggest a clean and flat design for the upcoming update. Apple is expected to release the software updates later this fall. Apple’s online store is down at the time of writing which suggests that the rumors about possible MacBook Air and MacBook Pro models could turn out to be true.

Apple earlier today released Mac OS X Lion GM seed to developers as it prepares for the official launch of the next major software upgrade. The Golden Master seed is the same version which will be made publicly available when the update hits Apple’s Mac App Store for $29.99.

Unlike previous software upgrades Apple will make OS X Lion exclusively available on Mac App Store. The download is expected to be around 4GB so if you’re are on a slower connection you might just have to wait longer before you can actually install the update.

Once Lion is purchased it will appear on your Dock, when you click the icon it will begin the installation process seamlessly. The upgrade will bring over 250 new user features which include but not limited to multi-touch gestures, resume, auto save, versions, air drop and much more.

Developers can download OS X Lion GM build by logging into the developer portal. A developer account is required to install and run this version.

During ‘Back to the Mac‘ event Apple explained that Lion has been inspired by the advancements made on the iPad. Full-screen apps and Launchpad are two such features which almost mimic the way Apple’s tablet works.

The release was expected in July and 9to5 Mac speculates based on rumors and reports OS X Lion could launch on July 14th and further suggests that the updated MacBook Air could also be unveiled on the same day.
