Warns you if someone is trying to access your camera or mic on you Mac. If you're a paranoid like me you will want it. You would be surprized to see who wants to gain access to your Mac when you don't want them to!
Occasionally turns into the top process consuming battery power, according to Activity Monitor (macOS Sierra 10.12.5) Energy>Energy Impact: runs my MacBook's battery down while it's in Sleep mode.
After installing this, my MacPro running 10.12.3. started completely freezing up randomly. After I removed it & did an Onyx cleanup, the freezing disappeared completely. FYI: I regularly do a cleanup every 3 weeks.
"Q: How is OverSight different than other tools (such as MicroSnitch)? A: OverSight is unique in a variety of ways:
• OverSight is 100% free (no demo mode, limited functionality, etc).
• OverSight is able to identify the process that is accessing the webcam. When your webcam's LED light randomly comes on, you'd want to know what process triggered that, right?
• OverSight provides the means to either 'allow' or 'block' a process that is accessing the webcam.
• OverSight can detect secondary 'consumer' processes that may be piggy-backing off a legitimate webcam session in order to stealthily record the user without detection. (See: "Getting Duped: Piggybacking on Webcam Streams for Surreptitious Recordings" for details on this novel attack)."
