A GM build is typically the final version of software that is to be made available to a wide release. It’s notable however that this release is called “macOS Sierra GM Candidate” suggesting that as a candidate it is possible there will be additional GM candidate builds if other bugs or issues are discovered with the release. Nonetheless if other GM builds are made available, they will certainly arrive from the Mac App Store Updates section as well.
Any user can choose to participate in the public beta program and gain access to the macOS Sierra GM build by signing their Mac up for the beta program here. Similarly, iPhone and iPad owners can opt to get the iOS 10 GM download as well by enrolling their iOS devices into the program.
For Mac users who want to make a macOS Sierra GM USB installer with the new build you’ll want to do so before starting the actual installation process.
The final public version of macOS Sierra will be released on September 20. MacOS Sierra includes a variety of new features for the Mac platform, including Siri support, enhanced iCloud integration, a universal clipboard, Picture in Picture mode, an enhanced Photos app experience, and many more subtle features and refinements.
