Download Sierra through CLI

EDIT:
Apple’s readded sierra to MAS

One of the changes that came with High Sierra’s release and affected fellow macadmins was the removal of Sierra from the app store.

 

For now, there’s a work around as Apple still has Sierra in the Software Update Catalogue

  1. Sign into the Mac App Store with an account that had Sierra
  2. Download Mas CLI https://github.com/mas-cli/mas
  3. Extract mac cli
  4. Drag mas into the Applications folder
  5. Open Terminal located in Applications -> Utilities
  6. type cd /Applications/
  7. type ./mas install 1127487414  This will download the installer Application
  8. Wait
