Micro Snitch 4+
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.
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.
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.
Micro Snitch shows notifications when devices become active or inactive. You can also enable notifications when devices are connected or disconnected.
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 (https://obdev.at/microsnitch/support.html), but there may be other compatibility issues that are not yet known.
Improved compatibility with macOS Ventura
Added option to turn off camera activity notifications on Apple Silicon Macs running macOS Big Sur and Monterey. Due to a bug in these macOS versions, the built-in camera may sometimes be incorrectly reported as active for a short moment. This bug has already been fixed in macOS Ventura.
Ratings and Reviews
updated to Catalina, doesn't fully work
Perhaps there is some permission I need to grant?
I gave it accessin "Accessibility". Odd thing is that it does (before and after the previous mentioned change) give me notifications, but my headset is listed as "Inactive". So, just deducting a single star now that I know it notifies.
Simple but imortant
This is a good one. It's by the makers of Little Snitch, a very popular and trusted network privacy monitor.
Don't pay attention to the old reviews saying that some devices don't work. It's worked great for me over the past year.
Thank you for updating to support Apple Silicon
I was hoping this app would update to support my M1 MacBook, and toady is the day! Thank you developers for updating your app with this support. I'm a big fan.
