OS X Yosemite 10.10.3 Beta 6 Available Now for Testing
Apple has released the sixth beta version of OS X Yosemite 10.10.3. The new build arrives as 14D127a and is available for those participating in the Public Beta test program and users who are registered as a Mac Developer.
Users who are eligible to receive the OS X Update Seed will find the download available now through the Mac App Store, accessible from the Apple menu. Installing the update requires a reboot. All users should back up their Macs before attempting to install any operating system updates, let alone beta software.
OS X 10.10.3 Yosemite mostly emphasizes the Photos app, which will replace iPhoto on the Mac. The new Photos app is similar to that which appears in iOS, offering a fluid thumbnail based approach for browsing and managing photo libraries. Photos app offers tie-ins to iCloud Photo Library, with automatic syncing between a Mac and an iPhone or other iOS devices.
Other feature enhancements and bug fixes are also to be included in OS X 10.10.3, though most of the other feature related changes are fairly minor, pertaining to things like Emoji icons and support for Google two-step authentication. The final list of bugs to be addressed in the update remains to be seen, but many beta users report anecdotally the new release performs well.
A public release date is not known for OS X 10.10.3, but a sixth beta build may suggest a final version is approaching soon. For now, the latest publicly available version of Mac system software remains OS X 10.10.2.
