Mac: While it is not easy for malware to hijack a Mac’s microphone or webcam, it is always a theoretical possibility. Oversight is a free app that will alert you every time the app tries to access your camera or microphone.
Surveillance works in much the same way as the previously mentioned Micro Snitch , except that it is free.
