Apple today released the second Yosemite public beta for beta testers, following the release of the sixth Developer Preview earlier this week. Apple has also released a new version of iTunes 12 for Yosemite.
The software update, build 14A329r, can be downloaded through the software update function of the Mac App Store.
Apple is expected to release OS X Yosemite to the general public later this year, possibly following an October event that may also introduce both the iWatch and new iPads.
