Apple on Monday released macOS High Sierra 10.13 beta 6, iOS 11 beta 6, watchOS 4 beta 6, and tvOS 11 beta 6 to registered developers. This new round of beta software comes a week after the release of beta 5 for these platforms.

iOS 11 beta 6

If you’re a developer with a device already running a previous beta version of iOS 11, you can upgrade to iOS 11 beta 6 (build number 15J5360b) over the air using the Software Update mechanism in the Settings app.

While we’re digging into new features and changes in beta 6, you can catch up with all that was new in beta 5 in this video:

watchOS 4 beta 6

Along with iOS 11 beta 6, Apple today seeded watchOS 4 beta 6 (build number 15R5357b) to the registered developers and members of its developer program.

If you’re a developer and would like to install watchOS 4 beta 6 on your Apple Watch over the air, tap My Watch → General → Software Update in the Watch app on your paired iPhone.

Non-developers are not permitted to test the software because the company’s official public beta-testing program currently does not support the watchOS platform.

You can watch everything that was new in watchOS 4 beta 5 in this video:

The iPhone maker today released a sixth beta (build number 15J5360b) of the upcoming tvOS 11 software update for the fourth-generation Apple TV to its registered developers and members of the paid Apple Developer Program, ahead of its scheduled release in the fall.
