Apple has seeded the eighth Developer Preview of OS X Mavericks to developers, nearly two weeks after the release of the seventh Developer Preview. Registered developers can receive the update via the Software Update tool in the Mac App Store. 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. Apple is reportedly targeting a late October launch for OS X Mavericks.
