Following the first betas of iOS 11.4, Today, Apple officially seeded the first developer betas of watchOS 4.3.1 and tvOS 11.4. Registers developers can download the new betas through Apple’s dev center, or they can be installed using each platform’s respective OTA updating mechanism.
Apple seeded tvOS 11.4 to developers. This follows the public launch of tvOS 11.3 last week, which brought with it only minor updates and features to the mix. It is likely that this release will continue that trend, with tvOS 11.4 likely only meant to fix behind-the-scenes bugs that may have cropped up since the public launch of tvOS 11.3. The new software may also be meant to enhance the overall experience and add general improvements as well.
To update, 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.
At the time of publication, it is not known what is new in the pre-release software. However, considering watchOS 4.3 was just released and welcomed new features like Portrait Mode for Nightstand Mode, as well as a few other additions, this new software is probably just meant to address any behind-the-scenes issues that have cropped up since the public launch of watchOS 4.3 last week.
To update, the Apple Watch needs to have at least 50 percent battery, it needs to be charging, and it has to be connected to the iPhone. For developers who already have the registered configuration profile installed, they can find the new software by going to the Watch app on their iPhone, then opening General –> Software Update.
If any new features are discovered in the new software, though, we will update this post accordingly.
