Install and launch

1. Download the Mac-Monitor DMG on a Mac running macOS 13 or later.
2. Open the DMG and drag Mac-Monitor.app to Applications.
3. Launch MacMonitor from Applications, then open its menu bar controls.

Set up your display

Enable DDC/CI in the monitor’s on-screen settings if available. Brightness and volume support depend on the monitor, connection and adapter; some displays expose only a subset of controls.

Open Settings to choose keyboard shortcuts and which displays respond. You can also configure launch at login; macOS may ask you to approve the login item.

If a control does not respond

1. Confirm the display is connected and detected by macOS.
2. Check DDC/CI settings on the monitor. Try a direct cable connection if you are using a dock or adapter.
3. Reconnect the display, reopen the app, and try the control again.

Check the changelog for fixes related to your setup.

Disconnect and reconnect

Disconnect removes an external display from the macOS layout; the monitor may then enter its normal no-signal standby. Use Reconnect to restore it. This does not guarantee a hardware power-off mode on every monitor.
