Apple is rolling out the final macOS Sierra Golden Master version to developers ahead of the software update’s official release next week. The release of the second macOS Sierra GM version comes more than a week after the first GM version of the new OS for Apple’s Mac devices was launched for developers to try out.

During the release of the first GM version, we reported that it was supposed to be the final test version of the upcoming operating system, but as it turns out, it was just the penultimate copy with the release of the second macOS Sierra GM version this Thursday.

MacRumors reports that the final Golden Master update with build code 16A323 is now available for download via the Apple Developer Center and that there is no indication yet if it’s going to be made available through the Mac App Store.

As the final test version ahead of the official release, the second macOS Sierra GM version should show improvements in the implementations of Sierra’s new features, such as the integration of Siri to Mac devices, the new Continuity feature called Auto Unlock that enables Apple Watch owners to remotely unlock their Mac devices using their smartwatch and the Universal Clipboard feature that allows users to copy text from one Apple device and paste it on another.

As previously reported, the previous betas for developers and public beta testers revealed that the new macOS Sierra will have deeper iCloud integration in order for users to easily retrieve any file saved in one of their Apple devices using a different one. In addition, the Safari browser was revealed to have been enhanced, such that it will now disable Flash content by default in favor of HTML5 content.

The sixth beta version of the macOS Sierra also comes with support for storing Microsoft OneDrive credentials in Keychain. The said beta also also came with a feature that enables Mac devices to identify Apple Pay-compatible Apple Watch and iPhones. And with the recent release of the iPhone 7, iPhone 7 Plus and Apple Watch 2, this would mean that the new devices would also be supported by this feature.
