MonitorControl
MonitorControl is a macOS utility that lets you adjust external display brightness, volume, and contrast from the menu bar or keyboard keys.
What is MonitorControl?
MonitorControl is a macOS utility for managing external display settings directly from your Mac. It helps users control brightness, volume, and contrast on supported monitors without reaching for the monitor’s physical buttons. The app integrates with the menu bar and can use standard brightness and media keys, making external displays behave more like native Apple screens. It also supports software dimming methods for displays and connection types that do not provide full hardware control. MonitorControl is especially useful for people who work with one or more external monitors and want faster display adjustments during everyday use. The project is maintained as an open-source Mac utility, with Joni Van Roost listed among its maintainers.

Safety overview
Status: Mostly safe
MonitorControl is a legitimate display-control utility for macOS. It may request Accessibility access if you want to use native keyboard brightness or media keys, which is normal for that feature. The app can also run in the menu bar so display controls stay available while you use your Mac. Hardware control depends on your monitor and connection type, so some setups may use software dimming instead of direct monitor control.
Recommendation: Keep MonitorControl if you use external displays and want quick brightness, volume, or contrast controls from macOS. If you no longer use it, you can remove it like other apps, but you may lose menu bar controls, keyboard integration, and saved display behavior.
