Apple today released macOS Sierra 10.12.6 as a free update to those who own a Mac computer. This comes two weeks after the sixth beta version of this operating system upgrade was released to early testers.
To update your Mac, head over to the “Updates” tab in the App Store. There, you’ll find the new build ready to install. Just click the “Update” button next to the macOS Sierra 10.12.6 listing and restart your Mac. The process may take a little while, so be patient and don’t turn off your Mac manually if you don’t have to.
Apple only includes bug fixes and security enhancements in macOS 10.12.6 which makes sense since this is a cumulative update. If you want new features like the Apple File System, you need to try out macOS High Sierra.
