Apple has seeded the fifth Developer Preview of OS X Mavericks to developers, approximately two weeks after the release of the fourth developer preview. The release comes as Apple continues to work on restoring full functionality to its Developer Center after bringing software downloads back online last week.
As noted by MacRumors forum members, the fifth Developer Preview of Mavericks includes both a new beta version of iPhoto (9.4.6) along with the iBooks app for Mac that was first unveiled at WWDC.
OS X Mavericks, which is expected to be released this fall, includes multiple new features like a tabbed Finder, full screen dual monitor capabilities, Safari improvements, and a new Maps app. Developers can receive the update via the Software Update tool in the Mac App Store.
Apple has also simultaneously seeded a new version of OS X 10.8.5 to developers.
