Apple today released the fourth beta of watchOS 4.3 for testing on the Apple Watch, two weeks after the third one was seeded. This comes after the fourth builds of iOS 11.3, tvOS 11.3, and macOS 10.13.4 were all released yesterday.
To install the beta, navigate to the Watch app on your paired iPhone and tap the “My Watch” tab. From there, go to General > Software Update and you should see the build ready for download. Be sure to place your iPhone on Wi-Fi while downloading this software as it’ll surely gobble up plenty of your data.
In watchOS 4.3, users can expect a portrait-oriented Nightstand Mode for when your Apple Watch is charging vertically, better control of music playback on your iPhone, and a new charging animation. There’s also, of course, bug fixes and security improvements. We’ll let you know of any other changes along the way.
