Components of the MacOS - Security - Enforce Lock Screen on Inactivity Worklet

The Worklet comprises two primary components:an evaluation script, and a remediation script.

Both elements are customizable to suit specific organizational needs. For example, you can adjust the desired_logout_seconds variable to set the auto logout time according to your preferences.

How does the MacOS - Security - Enforce Lock Screen on Inactivity Worklet work?

Upon execution, this Bash-based Worklet first checks whether an existing idle timer is already installed within your system. If not found, or if the configured settings do not match your desired values, it proceeds with remediation steps, such as creating an idle timer shell script and .plist file.

These files are then placed respectively within the "/Library/Application Support/Automox/" directory as "idle_timer.sh" and in the "/Library/LaunchDaemons/" directory as "com.idletimer.axtask.plist." Once these files have been created successfully, the launch daemon loads and schedules the idle timer check at regular intervals, as defined by the plist_interval variable.
