Know when someone spies on you!

Ever wondered if an application records audio through your Mac’s built-in microphone without your knowledge? Or if the camera captures video for no good reason?

With Micro Snitch there’s no doubt anymore. This ultra-light menu bar application operates inconspicuously in the background. It monitors and reports any microphone and camera activity to help you figure out if someone’s spying on you.

Fair enough, you might see the camera’s indicator light, but what if you are away from your computer? And for the microphone there is no activity indication at all, so you won’t notice if the microphone is turned on even if you’re sitting right in front of your Mac.

With Micro Snitch you always know whether some app is currently using your microphone and its logging facilities allow you to reveal any suspicious activities later on.

• Menu Bar Icon
Any current microphone or camera activity is displayed in the menu bar. The menu also shows a list of connected audio/video devices.

• Overlay
An on-screen overlay is shown while the micro­phone or camera is turned on to make sure you won’t miss it even if the menu bar isn’t currently visible.

• Logging
Never miss any microphone or camera activity, even in your absence. Every status change is logged to a file, so you can review it later to find suspicious activities.

• Notifications
Micro Snitch shows notifications when devices become active or inactive. You can also enable notifications when devices are connected or disconnected.

• Accessibility
Micro Snitch plays nicely with the accessibility features built into OS X, like VoiceOver. By pressing a configurable hotkey, Micro Snitch shows the current microphone or camera activity textually, which VoiceOver reads automatically.


Note: Micro Snitch was tested with as many different Mac computers and audio/video devices as we could get our hands on. The limitations we found are documented in the “Compatibility” section of the Micro Snitch FAQ (, but there may be other compatibility issues that are not yet known.

Works as described. If I launch Facetime, notification pops up letting me know built-in facetime HD camera is being used and the status bar icon fills in with solid white. Take a chance, you won’t be disappointed.

Since I don’t want to put “tape” on my MacBook...

I am using the MacBook Pro (Retina, 15-inch, Mid 2015) with OS X 10.11.6 El Capitan (15G1004) and have zero issues with operation. It works exactly as described by showing notifications as well as logging activity for later review. Excellent program that keeps your Mac looking “professional” but you can always play it safe and add the tape if you’re paranoid.

If you are concerned about equipment compatibility, they offer a free, download to test and see if it works so I’d recommend that before buying it and then complaining it does not work.
