Micro Sniff
Micro Sniff is a lightweight macOS menu bar utility that alerts you whenever your Mac’s microphone is actively being used.
What is Micro Sniff?
Micro Sniff is a macOS utility that helps users notice when their microphone is active. It runs from the menu bar and shows an on-screen indicator whenever an app starts using the microphone, making it easier to spot unexpected audio access during calls, recordings, browser sessions, or other microphone-based tasks. This can be useful for privacy-conscious users who want clearer visibility into microphone activity beyond what they might otherwise notice. The app is designed as a small focused helper rather than a full security suite, so its main job is simple: notify you when microphone use begins. Micro Sniff is published by Dwarves Foundation and is offered for Mac as a utilities app.

Safety overview
Status: Mostly safe
Micro Sniff’s behavior is consistent with its purpose as a microphone activity notifier. To work properly, it may need normal macOS permissions related to monitoring microphone use or displaying an on-screen indicator. That access is expected for this kind of utility, but you should still install it only if you want this feature and review any permissions it requests. Removing the app stops its microphone-use alerts but should not affect normal microphone operation in other apps.
Recommendation: Keep Micro Sniff if you want a simple visual reminder whenever your microphone is active. If you do not use microphone monitoring or prefer macOS’s built-in indicators alone, you can remove it without affecting your other apps beyond losing its alerts.
