Apple is seeding a fourth Developer Preview of OS X Mavericks
, users note. Any significant changes have yet to be identified. The new beta is arriving just under two weeks after the previous one
, which went out July 9th.
The finished version of Mavericks is due to ship sometime this fall. It will introduce a variety of features to OS X, such as Finder tabs, Mac versions of Maps and iBooks, and technical improvements like App Nap, compressed memory, and expanded multi-monitor support.
