Apple is following up its release of iOS 8.4 beta 4 this morning with a new beta build of OS X 10.10.4 for developers.
The update promises to improves the stability, compatibility and security of your Mac with a bevy of bug fixes, and is being released alongside a third beta of Xcode 6.4.
Details about new features weren’t included in the OS X 10.10.4 seed note; however, Apple has asked developers to focus on Photos, Migration and Arabic and Hebrew. While OS X 10.10.3 added a number of new features, including improved emoji, OS X 10.10.4 has been mostly focused on under-the-hood fixes.
OS X 10.10.4 beta build 14E17e can be downloaded directly from the Mac Dev Center or from the Updates section in the Mac App Store if your computer is already running an older OS X 10.10.4 beta.
