On Monday Apple released eighth beta releases iOS 11, watchOS 4, macOS 10.13 and tvOS 11 to registered developers. New betas were released just a week after the previous ones were released, and there are still two weeks before the conference iPhone 8. Most likely Apple is already ready to release public versions of the system.
iOS 11 beta 8
If you are a registered developer and you already have a previous beta version iOS 11, you can upgrade to the latest 'over the air' through the Software Update mechanism in Settings.
We will also install update iOS 11 beta 8 to look for new features and changes.
macOS 10.13 beta 8
MacOS High Sierra 10.13 beta 8 can also be downloaded over the air in Mac Updates App Store. If you don't have a previous beta installed, the setup file can be downloaded from Apple Dev Center.
watchOS 4 beta 8
Registered developers with Apple Watch who have a previous beta version can install the update via the Software Update in Settings.
tvOS 11 beta 8
Developers with a suitable profile on their Apple TV (4th generation) can install a new beta through Settings> System> Software Update.
Otherwise, you will need to connect Apple TV to your Mac and download the file from Dev Center. tvOS 11 is the most modest update with the fewest changes.
