How do I see which app is using my Mac microphone?
Tested on macOS 26.4.1 (Tahoe), Apple M3 Max, 3 Sept 2026. Updated 2026-09-03.
You can see which app is using your Mac microphone by clicking the Control Center icon in the menu bar: an orange dot next to it means the microphone is in use, and the top of Control Center names the app. If the dot stays after the app is closed, a background process still holds the input. Quit it from Activity Monitor, or revoke its access under System Settings > Privacy & Security > Microphone or with one tccutil command.
What does the orange dot next to Control Center mean?
Apple's Control Center guide states it directly: "An orange dot next to the Control Center icon in the menu bar indicates the microphone on your Mac is in use." The dot is drawn by the system, not the app, so an app cannot hide it. It appears when any process opens an audio input through Core Audio and disappears when the last one closes it.
To find the app:
- Click the Control Center icon at the right end of the menu bar.
- Read the field at the top. As Apple puts it, "the top of the window may contain a field that shows which apps are using your microphone, location, camera, or system audio."
- Click that field to open the matching Privacy & Security pane, which lists every app with a grant.
Tested on macOS 26.4.1: the field shows the app's name and icon while the input is open and clears within a second or two after it closes. "System audio" is listed too, so on macOS 26 Tahoe a recorder capturing what the Mac plays appears there although no microphone is involved. That is the Screen & System Audio Recording permission at work, explained in Screen & System Audio Recording permission not showing.
How do I stop an app from using the microphone?
Work from the least to the most forceful option.
- End the call or recording inside the app. Most apps release the input at that point.
- Quit the app with Cmd-Q. Closing a window is not enough; menu-bar and background apps keep running.
- Force quit from Activity Monitor (Applications > Utilities). Search for the app's name, select it, click the X button. This also catches helper processes that keep the mic open after the main window closed.
- Revoke access in System Settings > Privacy & Security > Microphone. Apple's guide: "Turn access to the microphone on or off for each app in the list." The app cannot open the input again until you turn it back on.
- Reset the decision from Terminal so the app has to ask again:
tccutil reset Microphone com.example.app. The manual page describes this as causing "apps to prompt again the next time they access the service."
Documented failure mode: the orange dot persists with no app named in Control Center. That is usually a helper process with no window, such as a meeting app's audio helper or a dictation service. Activity Monitor with the vendor's name in the search field finds it. If the dot survives even that, sudo killall coreaudiod restarts the audio daemon; every input is closed and the dot clears.
Can I check microphone use from the Terminal?
Partly. There is no single command that lists "apps recording right now", and the usual tools mislead:
lsofdoes not help. Apps do not open the microphone as a file; they talk to thecoreaudioddaemon.lsofon the app shows no audio device, and oncoreaudiodit shows the daemon's own files, not its clients.system_profiler SPAudioDataTypelists every input and output device with channel counts, useful for confirming a device exists, but says nothing about who is using it.
What does work:
- Find and end a suspected process:
pgrep -l -i zoomlists matching processes, thenkill <pid>. - Revoke and reset the grant:
tccutil reset Microphone com.example.app. - Last resort:
sudo killall coreaudiod.
The database behind the Microphone pane is protected, so the pane itself is the practical view of who is allowed. For whether an app may record at all, see Mac microphone permission not working; for a recording of your own that came out silent, start with why is my Mac not recording sound.
Why does it matter for my own recordings which app holds the mic?
Two apps can open the same microphone at once on macOS; Core Audio gives each client the stream. A second app holding the mic does not block your recorder. It causes two other problems:
- Bluetooth quality. If the open microphone belongs to a Bluetooth headset, the headset is in the Hands-Free Profile: mono, 8 or 16 kHz, for playback and capture alike. Your built-in-mic recording is fine, but everything you monitor through the headset sounds like a phone call until the other app releases the mic. Detail in Bluetooth headphones make Mac recordings sound bad.
- Exclusive access. Some DJ and DAW apps open an audio interface exclusively. Your recorder then sees the interface but receives no buffers. The orange dot says an input is open; Activity Monitor says by whom.
A recorder that captures system audio instead of a microphone is affected by neither, because it opens no input device. It still appears in Control Center under "system audio" on Tahoe, which is correct behaviour, not a leak.
When you open Control Center, the top of the window may contain a field that shows which apps are using your microphone, location, camera, or system audio.

Ways to find and stop the app using the microphone
| Method | Shows app name | Stops it | Prevents next time | Needs Terminal |
|---|---|---|---|---|
| Orange dot plus Control Center | yes | no | no | no |
| Privacy & Security > Microphone toggle | no, shows grants | yes, on next open | yes | no |
| Activity Monitor force quit | yes, by process | yes | no | no |
| tccutil reset Microphone <bundle id> | no | no | yes, until re-granted | yes |
| sudo killall coreaudiod | no | yes, every input | no | yes |
Where AirCheck fits
AirCheck opens a microphone or interface only while a take is running, so the orange dot and the Control Center field appear when you press Record and clear when you stop; no background helper keeps the input open. For a system audio take it opens no microphone at all and is listed under system audio instead. AirCheck is $39 once, needs macOS 14 Sonoma or newer, and records one source per take to 24-bit AIFF before export.
When you do not need it: Finding and stopping a rogue app needs no third-party tool; Control Center, Activity Monitor and System Settings cover it. If you only need to know whether your mic is on, the orange dot answers that for free.
AirCheck records what your Mac plays, or any input, to one file. $39 once.
macOS 14 or newer. One-off payment. Fourteen-day refund, no questions asked.
Questions people ask
Why is the orange dot on when no app is open?
A background process still holds the input, often a meeting app's helper or a dictation service. Open Activity Monitor, search for the vendor name, and quit the helper. If the dot remains, run sudo killall coreaudiod to close every input.
Can an app use my microphone without the orange dot?
Not through the normal audio APIs. The indicator is drawn by macOS whenever any process has an audio input open. Apps that have been granted Microphone access can open it without asking again, which is why revoking the grant matters.
Does system audio recording show the orange dot?
On macOS 26 Tahoe the Control Center field lists apps using system audio alongside microphone, camera and location. A recorder capturing what the Mac plays appears there, but it opens no microphone, so the orange microphone dot is not the indicator to watch for it.
