OverSight

OverSight is a lightweight security monitoring tool developed by Objective-See that watches your Mac's microphone and webcam in real-time. It displays visual and audio alerts whenever these sensitive hardware resources are accessed by any application, helping you detect unauthorized or unexpected use. The app runs quietly in the background and is particularly useful for privacy-conscious users who want transparency into which apps are attempting to use their camera or mic. It's a popular choice among security researchers, journalists, and anyone concerned about protecting their digital privacy on macOS.
