After developer beta releases for iOS, watchOS, and tvOS on Monday, Apple has released a second beta of macOS Sierra 10.12.4 beta for developers alongside a second beta release of iOS 10.3.

Apple included a new Night Shift mode borrowed from iOS in the recently released macOS Sierra 10.12.4 beta, promising a low blue light viewing experience for nighttime computer work. Other than the Night Shift addition for macOS, it is not known what new features, if any, are included with the 10.12.4 beta.

Tuesday's macOS Sierra 10.12.4 beta has a build number of 16E154a. Developers can obtain it through the "software update" on registered devices.

Apple's iOS 10.3 contains a bevy of new features, including a device file system upgrade to APFS, a new "Find My AirPods" ability, additions to Siri, CarPlay improvements, and some changes to Maps.

Monday's releases for developers included second developer beta releases of iOS 10.3, watchOS 3.2, and tvOS 10.2.
