Alongside iOS 11.4.1 beta 1, Apple on Wednesday seeded the first betas of macOS 10.13.6, tvOS 11.4.1 and watchOS 4.3.2.
Each of the updates appear to be minor in scope, new software designed to address any issues that were discovered in previous version of the platforms. At the time of publication, it is not known what, if anything, is new for the end user in the new versions of the platforms, but if anything is discovered we will update this post accordingly.
To update to macOS High Sierra 10.13.6, the proper configuration profiles must be installed. Once they are, the new software can be downloaded and installed from the Mac App Store by selecting the Updates tab and choosing to install the new software.
Updating to watchOS 4.3.2 requires that the Apple Watch has at least 50 percent battery, it needs to be charging, and it has to be connected to the iPhone. Once all that’s covered, you’ll use the stock Apple Watch app to go through the update process.
Finally, to update supported Apple TV set-top boxes to tvOS 11.4.1, developers must have the proper configuration profile installed, and the Apple TV set-top box must be connected to a computer so the pre-release software can be setup via Xcode. If the developer already has a registered fourth- or fifth-generation Apple TV, they can also turn on automatic updates, which will pull down the latest beta seed as well.
It is possible that Apple will seed corresponding public betas of the pre-release software ahead of a public launch as well, which may arrive next week.
