OverSight

OverSight is a free, real-time monitoring tool from Objective-See that alerts users when their Mac's microphone or webcam is activated. It sits in the menu bar and logs all access attempts with detailed information including which app triggered the camera or mic, how long it was in use, and data about the process. OverSight is widely used by security-conscious macOS users, privacy advocates, and security professionals to catch unauthorized surveillance attempts or verify that system access is legitimate. The app provides both visual notifications and an archived history of all microphone and camera access, helping users maintain visibility over two of the most privacy-sensitive hardware components on their machine.
