Apple today released the third Yosemite public beta for beta testers, following the release of the second Yosemite public beta on August 21. Developer Preview 8 has also been released for developers, two weeks after the seventh Developer Preview was released.

The software update can be downloaded through the software update function of the Mac App Store, and developers can also download DP 8 from the Mac Developer Center.

It is possible given the release timing that both versions of Yosemite, DP 8 and the new public beta, are the same. The public beta will also include updates from Developer Preview 7, which included a new look for Dark Mode, several tweaked icons, and the removal of the "Software Update" option from the main Apple menu.

Apple is expected to release OS X Yosemite to the general public later this year, possibly following an October event that may introduce new iPads.
