How to Download and Install macOS Sierra
The latest operating system update for MacBooks and desktop Macs, macOS Sierra, is finally here. Besides eschewing the OS X moniker, Sierra finally brings Siri to the Mac, alongside picture-in-picture, updated Photos app, Apple Pay in Safari and the ability to unlock your computer with an Apple Watch.

4. Agree to the terms and conditions.
5. Click Agree in the pop-up box.
6. Click Install when it shows your boot drive.
