Stop High Sierra Installs and Updates

With High Sierra causing so many issues for Enterprise environments at the moment you may want to block the install. This can be achieved in various ways.

If you are using Jamf MDM then a simple Restricted Software policy can stop the install:

However this won’t stop macOS downloading the updater in the background and prompting the user to install, but there are two other commands we can issues to try and stop auto updates and notifications:

To stop Auto Updates:

defaults write /Library/Preferences/ AutomaticCheckEnabled -bool FALSE

To turn Auto Updates back on:

defaults write /Library/Preferences/ AutomaticCheckEnabled -bool TRUE

To turn off High Sierra notifications

sudo softwareupdate --ignore macOS High

An when you do want to allow notifications you can switch it back on with:

sudo softwareupdate  --reset-ignored
