Apple today released macOS Sierra 10.12.6, the sixth update to the macOS Sierra operating system that launched in September of 2016. macOS Sierra 10.12.6 comes two months after the release of macOS Sierra 10.12.5, an update that introduced a headphones audio fix, enhanced Mac App Store compatibility, and more.

macOS Sierra 10.12.6 is a free update for all customers who have a compatible machine. The update can be downloaded using the Software Update function in the Mac App Store.

There were no bug fixes, feature additions, or other changes found in macOS Sierra 10.12.6 during the beta testing process, suggesting the update focuses on security improvements and other small enhancements.

macOS Sierra 10.12.6 is likely to be one of the last updates to the macOS Sierra operating system, as Apple is preparing to shift focus to macOS High Sierra, the next version of macOS. Apple introduced macOS High Sierra at the Worldwide Developers Conference on June 5.
