On this day, Apple released iOS 10.2 beta 6 watchOS 3.1.1 beta 5 and beta 5 macOS 10.12.2. Developers can install updates via the company development portal, from the respective update mechanisms that are included in the operating systems. It is worth noting that betas of iOS 10.2 and macOS are also available for betatesters who have subscribed to the company's testing program.
The new betas come to light a week after Apple released developer beta 4 and a few days after the release of iOS 10.2 beta 5. The rapid deployment suggests that we are close to seeing public versions of the software, probably before closing ITunes Connect vacation in 2 weeks.
From what we have seen in the betas so far, IOS 10.2 includes a lot of improvements, including new emoji, wallpapers, settings and more. On the other hand, macOS 10.12.2 watchOS 3.1.1, seem to be the typical maintenance updates and the naked eye, do not seem to have many changes aimed at improving the user experience.
