Apple on Tuesday provided members of its public beta testing programs with pre-release builds of both iOS 9.3 and OS X 10.11.4, a day after the fourth betas were provided to developers.
iOS 9.3 beta 4 can now be accessed by public beta program members through Software Update on a registered device. Likewide, OS X El Capitan 10.11.4 beta 4 is available through the Mac App Store on a registered Mac.
iOS 9.3 beta 4 is identified as build 13E5214d, and OS X 10.11.4 is 15E49a.
iOS 9.3 brings with it a number of new features, notably the sleep-enhancing Night Shift mode. The iPad gains multi-user login for educational customers, while Music, CarPlay, and Health have also received some attention.
AppleInsider also detailed last week how the forthcoming update will allow third-party apps to match songs to an Apple Music user's iCloud Music Library directly from the device.
OS X 10.11.4 includes a handful of new features, like individually encrypted items in Notes, and support for displaying iPhone 6s Live Photos in Messages. It also patches a bug related to opening links on Twitter via Apple's Safari browser.
Not part of Tuesday's release are watchOS 2.2 or tvOS 9.2, as neither the Apple Watch nor the fourth-generation Apple TV are part of Apple's public beta program.
