Apple Seeds Third macOS Sierra 10.12.1 Beta to Developers
Apple today seeded the third beta of an upcoming macOS Sierra update to developers for testing purposes, nearly one week after seeding the second beta and two weeks after releasing the new macOS Sierra operating system to the public.
macOS Sierra 10.12.1 beta 3 can be downloaded from the Apple Developer Center or through the Software update mechanism in the Mac App Store.
macOS Sierra 10.12.1 appears to focus on bug fixes and under-the-hood performance improvements to address issues that have been found since the operating system's release. Few outward-facing changes were discovered in the first two betas, but it does include Photos support for the new iPhone 7 Plus Portrait feature introduced with iOS 10.1. New features discovered in the third 10.12.1 beta will be listed below.
macOS Sierra is a significant update that brings features like Siri support, a new storage optimization option, cross device copy paste, auto unlocking with the Apple Watch, and more. For full details on macOS Sierra, make sure to check out our roundup.
