Control Center
Click the Control Center icon to open Control Center, where you can access features you use often, such as AirDrop, Stage Manager, Screen Mirroring, Focus, and more. See Use Control Center.
Privacy indicators, which can be dots or arrows, are located to the right of Control Center. An orange dot next to the Control Center icon in the menu bar indicates the microphone on your Mac is in use; a green dot indicates a camera is in use; a purple dot indicates the system audio is being recorded; and an arrow indicates your location is in use. Only one privacy indicator dot is shown at a time. For example, if both the microphone and a camera are in use, you only see a green dot. When you open Control Center, the top of the window may contain a field that shows which apps are using your microphone, location, camera, or system audio. You can click that field to open the Privacy window, which may have additional information (macOS 13.3 or later).
