Apple today seeded the second beta of an upcoming watchOS 4 update to developers for testing purposes, nearly two weeks after releasing the first watchOS 4.1 beta and three weeks after releasing the new watchOS 4 operating system to the public.
Once the proper configuration profile has been installed from the Apple Developer Center, the new watchOS 4 beta can be downloaded through the dedicated Apple Watch app on the iPhone by going to General --> Software update.
To install the update, the Apple Watch needs to have at least 50 percent battery, it must be placed on the charger, and it has to be in range of the iPhone.
The watchOS 4.1 update introduces support for streaming Apple Music content directly to the Apple Watch Series 3 over LTE and it brings a new Radio app with access to Beats 1 and other Apple Music radio stations.
While the Music app on the watch looks the same, offering up access to the Music Library, recently played songs, playlists, and Apple Music mixes, but now all Apple Music content can be streamed over an LTE connection and doesn't need to be downloaded to the device.
Support for Apple Music streaming appears to be the main feature in the new watchOS 4.1 update, but Apple is also introducing new Unicode 10 emoji characters. Today's update adds a new Wi-Fi toggle for turning off Wi-Fi to force the Apple Watch Series 3 to use LTE and it displays the Wi-Fi SSID so users can see the Wi-Fi Network an Apple Watch is connected to.
watchOS 4 is a significant refresh of the watchOS operating system introducing new watch faces, including a personalized Siri face, improvements to the Workout app, support for integration with gym equipment, an Apple News app, a vertical Dock, and a new Flashlight feature in the Control Center.
