Script to Change Screen Brightness on Mac

Users can change the brightness levels on macOS devices with the help of dedicated function keys or using the System Preferences. Despite these alternatives, administrators can directly run the Terminal commands to adjust brightness on Mac. Hexnode enables you to run these commands as scripts remotely using the Execute Custom Script action.

Disclaimer:


The Sample Scripts provided below are adapted from third-party Open-Source sites.

Pre-requisites:

  1. This script requires Homebrew and the associated command-line brightness control tool to be installed on the devices.
