To go along with this morning’s third iOS 7 beta, Apple has released OS X Mavericks Developer Preview 3. This new preview arrives two weeks following Preview 2. Like Preview 2, it seems likely that Preview 3 focuses on bug and performance fixes.

OS X Mavericks launches for the general public this fall with new Maps and iBooks apps, significant battery life, scrolling, and overall performance adjustments, and power-user features like revamped multiple-monitor support, Finder Tags, Finder Tabs, and a faster Safari browser.
