Apple has reportedly commenced internal testing of Mac OS X 10.7 which indicates WWDC 2011 will be the time and place to make the software available to the general population.

Sources close to TUAW are signaling that OS X Lion has been in internal testing since last week. If everything goes according to plan, the software should launch publicly at the Worldwide Developers Conference 2011 keynote address (June 6).

On March 28, Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing said “At this year’s conference we are going to unveil the future of iOS and Mac OS. If you are an iOS or Mac OS X software developer, this is the event that you do not want to miss.”

Apple not only stated its intentions to offer a deeper look at Lion during WWDC 2011, but the company had already confirmed a rough shipping timeframe, and that date is approaching.

In February, when Apple released the first Developer Preview of Lion, the company confirmed that “The Lion preview is available to Mac Developer Program members through the Mac App Store today, and the final version of Lion will ship to customers this summer.”

Mac OS X Lion takes some of the best ideas from the iPad version of iOS and brings them “back to the Mac,” as Apple advertised the software in February.

The eighth major release of OS X, Lion delivers key new features like Mission Control, a new view of everything running on your Mac; Launchpad, described as “a home” for all of the Mac apps residing on your hard drive; full screen apps, new Multi-Touch gestures and more. Lion will ship with the Mac App Store pre-installed.

Softpedia recently raised the subject of OS X Lion pricing asking its readers how much they are willing to pay for the upgrade. Join the discussion here, or learn more about OS X Lion here.
