Apple has released OS X Yosemite Public Beta 3 to those Mac users registered with the public beta program. Additionally, Apple released OS X Yosemite Developer Preview 8 to Mac developers. The two builds include bug fixes and feature enhancements, and appear to largely be the same, pushing the release of OS X 10.10 ever closer to the public launch this fall.
Separately, OS X Yosemite Beta Recovery 1.0 is also available as an update, which is aimed at resolving issues with the recovery boot partition for Yosemite beta users.
Mac users who participate in the beta and development programs for OS X will find the relevant updates available to download from the Mac App Store, accessible from the Apple menu.
Release notes accompanying the Mac App Store updates are brief as usual, simply suggesting that “This update is recommended for all users.”
