Apple Seeds watchOS 4 Golden Master to Developers

Apple today seeded the golden master (GM version) of watchOS 4 to developers following a beta testing period that saw the company release a total of eight betas. The golden master version of watchOS 4 represents the version of the software that will be released to the public on Tuesday, September 19.

Once the proper configuration profile has been installed from the Apple Developer Center, the new watchOS 4 golden master 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.


watchOS 4 brings three new watch faces, including a dedicated Siri watch face that displays dynamic information unique to each individual user. There are new complications for Now Playing and Apple News, and an enhanced Workout app that supports High Intensity Interval Training and new swimming options.

GymKit, new in watchOS 4, lets the Apple Watch interface with gym equipment for workout data sharing purposes, and the Activity app has been updated to provide intelligent coaching, monthly activity challenges, and tailored workout encouragement.

Starting a workout is faster than ever with a new Quickstart interface, there's a new look for Apple Music, and with under-the-hood improvements, third-party apps are faster than ever and can do more.

Apple plans to release watchOS 4 to the public on Tuesday, September 19, three days ahead of when the new Apple Watch Series 3 will be available to consumers.

The heart rate capabilities were the best part. I liked the in depth Monitoring aspect.
Agree, really looking forward to having this kind of unique data the watch collects better exposed and proactively monitored. A great idea.

Just installed the GM. I'm not seeing the new HR monitor functionality nor am I seeing the red arms on the faces (assuming this is for LTE only).

Has anyone on WatchOS 4 been able to get the watch to sync to fitness equipment yet?

Is this not a public beta?
There isn't (and probably never will be) a public beta for watchOS.

If you are not a developer, you will have to wait until the official release.
