Apple has released the final version of macOS Sierra 10.12.6 for Mac users running the Sierra operating system.
The update includes bug fixes and security enhancements, but does not provide any new features or major changes to the operating system.
Separately, Mac users running El Capitan and Yosemite will find security updates available as well.
How to Download & Install macOS 10.12.6
Always back up a Mac before installing any software update, even smaller point releases. Time Machine is easy to setup and use for backups. The easiest way for Mac users can download and install macOS Sierra 10.12.6 is via the App Store:
- Pull down the Apple menu and choose “App Store”
- Go to the “Updates” tab and choose the ‘update’ button next to “macOS Sierra 10.12.6” when it becomes available
The Mac will install and update to the latest version of Sierra and then reboot when complete.
An update to iTunes 12.6.2 is also available in the Mac App Store.
Aside from Sierra, for those on Mac OS X Yosemite and OS X El Capitan, Security Update 2017-003 is available for each release in the Mac App Store as well.
macOS 10.12.6 Combo & Delta Updates
Mac users can also choose to install the latest version via a Combo Update or Delta update, available to download at Apple:
Using a combo update in Mac OS is fairly simple, as is using the delta update. Nonetheless, most Mac users are better served keeping things easier by just installing the update through the Mac App Store.
Direct links for concurrent 2017-003 security updates for prior Mac OS X releases are available as well:
Those security updates are bundled into macOS Sierra 10.12.6 if applicable, which is why there is not a separate security update release for Sierra.
