Apple releases macOS Sierra 10.12.4 Beta 3 for developers

20 February 2017 0

Apple is on its software deployment cycle once again, where it releases new beta versions of all its platforms, including iOS, watchOS, and tvOS. Apple just released iOS 10.3 Beta 3 for developers, and now is also seeding the third beta of its macOS Sierra 10.12.4 to registered developers.

The update comes almost two weeks after the last release, which was the 10.12.4 second beta for public testers on February 7th. The third beta also brings native support for Night Shift mode to macOS. Originally a feature from iOS, the Night Shift mode is essentially a blue light filter for working during late hours, which helps maintain regular sleeping patterns.

Some other new features include system APIs for reading and writing PDF files, support for Shanghainese, and many performance enhancements/bug fixes.

Check out how the new Night Shift feature in macOS Sierra works:

The new update can be found in the Updates section of the Mac App Store. If you're a registered tester, you should be able to see updates available. If you want to become a part of Apple's testers' circle, then you can sign up on the official website.
