Preview at WWDC likely in June, followed by September launch.
Apple Releases OS X Yosemite Developer Preview 2
The update, Developer Preview 2, has a build number of 14A261i, and can be downloaded from the Mac App Store or the Mac Dev Center.
OS X Yosemite brings a flatter, more modern look to OS X, with an emphasis on translucency, along with a slew of new features, including improved integration with iOS 8 through Continuity. It also includes a new "Today" view in Notification Center that offers integration with third-party apps, a retooled Spotlight search that offers new data sources, and several new features for apps like Mail, Safari, and Messages.
OS X Yosemite is currently only available to developers, but Apple plans to offer a beta version of the software to Mac users at some point during the summer. A public release of OS X Yosemite is expected in the fall, after several additional beta iterations.
- Photo Booth: Photo Booth, which was missing from the first Yosemite beta, has now returned.
- Time Machine: Time Machine has a redesigned interface that removes the stars. (via 9to5Mac).
- Screen Sharing: Screen Sharing has been updated to version 6, allowing users to block incoming screen share requests.
- Settings: There's a new Settings icon.
- AirDrop: AirDrop now offers a notification directly on the screen when a file is incoming, so it is no longer necessary to open Finder to receive a file (via 9to5Mac).
Handoff: According to several of our forum members, Handoff between iOS 8 and OS X Yosemite is now far more functional.
System Information: There's a new field for Continuity support in the Bluetooth category of the System Information app, which lets users know if their machines support features like Continuity and AirDrop.
