Apple activated single sign-on for Apple 4 tvOS 10.1 and iOS 10.2 devices for beta users. The feature was already announced in June and now Apple has also phased the beta phase for this service.
If you are a registered developer with Apple, you will get new pre-versions of iOS 10.2, macOS Sierra 10.12.2, watchOS 3.1.1 and tvOS 10.1. Apple has now updated all its operating systems, at least for developers. What exactly is hidden at innovations in the updates, has been determined by first tests, but not exactly documented, at least with watchOS 3.1.1 and macOS Sierra 10.12.2 but it should be at most minor updates.
After Apple has already released iOS 10.1.1 for all, the developers are now to get an update, or more exactly four updates. Apple has released all operating systems, which are currently up-to-date, in a pre-release version. Although not documented, what might have changed is called to the cheers test.
The new versions of the four operating systems from Apple are currently only available to developers. Apple itself has not documented what has changed. However, some innovations have already been discovered on the Internet.
In iOS 10.2, for example, new background images were made. These are water drops in different colors, which were already on the “hello again” -Keynote on screenshots to be seen. There are also new emojis. Apparently, Apple has added the new images, which have been specified in Unicode 9.0. This should also be one of the changes in macOS Sierra 10.12.2 Beta 1. In addition, iOS 10.2 Beta 1 has a new widget for the video app and the camera settings can be retained for the next session.
