Apple has just seeded the fifth beta of macOS Sierra to developers and public beta testers, just over one week after seeding the fourth beta and a month after releasing the new macOS Sierra operating system to the public.
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, and it’s also likely adding features designed for next-generation MacBook Pro models set to be released later this year.
Few outward-facing changes were discovered in the first four betas, but it 10.12.1 does include Photos support for the new iPhone 7 Plus Portrait feature introduced with iOS 10.1. New features discovered in the fifth 10.12.1 beta will be listed below.
The new beta can be installed as an over-the-air update via the Mac App Store for machines that are already running the fourth beta. It’s also available on Apple’s dedicated site for developers.
