OS X 10.10.3 Beta 4 Released for Testing
Apple has released the fourth beta of OS X 10.10.3 Yosemite for testing. The new beta build arrives as 14D105g and includes updates to the OS X 10.10.3 system software and seems to continue focus on the new Photos app for Mac. Additionally, the new beta build apparently fixes a bug that impacts newly released Mac hardware.
Mac developers and Mac users participating in the OS X Public Beta programs can find the new version available to them through the Software Update mechanism of OS X, accessible from the Apple menu > App Store > Updates. The download itself is labeled as “Pre-release OS X Update Seed 10.10.3” and is around 1GB in size, requiring a reboot to complete installation of.
OS X 10.10.3 is said to include various bug fixes, feature enhancements, but perhaps most notable is the inclusion of the new Photos app. Photos for OS X resembles Photos for iOS in many ways, and will be familiar to use for those coming to and from an iPhone or iPad, the app will replace iPhoto moving forward.
While anyone can sign up to participate in the OS X Yosemite Public Beta program (and a similar program for iOS betas), it’s generally not recommended to run beta software on a primary Mac, instead it would be more appropriate to run beta operating system software on a secondary machine that is not particularly mission critical or containing any important data. Always back up your Mac before updating, and always back up before running beta software.
There is no known final release date scheduled for OS X 10.10.3, but the pace of beta releases is picking up, perhaps indicating that a widespread release is nearing.
