Which Apps Can Access Your Mac's Microphone? Here's How to Check

The Mac’s microphone permission system is solid in principle: apps have to ask before they can listen, and you get a dialog. The orange dot in the menu bar tells you when the mic is in use right now.

The weakness is the long term. Every app you’ve granted mic access to keeps it forever, unless you go in and revoke it. After three years of installing voice memo apps, video chat tools, podcast clients, and “transcribe my meeting” utilities you used twice, the list of apps with mic permission can be long. Most of them shouldn’t have it anymore.

Where the mic permission list lives

System Settings → Privacy & Security → Microphone. On older macOS, System Preferences → Security & Privacy → Privacy → Microphone.

You see every app that’s ever asked for mic permission, with a toggle for each. On means the app can listen any time it wants (with the orange dot indicator). Off means the app cannot, until you re-enable.

Apps that have never asked for mic access aren’t in this list — there’s nothing to revoke for them.

A typical Mac’s list

After a year or two of normal use, your list probably includes:

• Always reasonable: Zoom, Microsoft Teams, Google Meet (via browser), Webex, Slack, Discord
• Probably reasonable: Voice Memos, GarageBand, Logic, Audacity, Voice Control if you use it
• Maybe reasonable: Photo Booth, QuickTime, screen recorders with audio
• Often unnecessary: Old transcription apps, abandoned podcast clients, note apps with voice memo features you never used, “translate this” tools

The last category is where you’ll prune.

How to do the audit

1. Open System Settings → Privacy & Security → Microphone
2. Scroll the entire list
3. For each app: have I used its mic feature recently?
4. If no, toggle off
5. If you don’t recognise the app at all, definitely toggle off

That’s the whole thing. Five minutes.

If you accidentally revoke an app you actually use, no permanent damage — it’ll prompt next time. You allow, life goes on.

Browsers and per-site mic permissions

Browsers have system-level mic permission like other apps, but each website inside the browser also has its own per-site mic permission. This means a browser with mic permission still requires individual sites to ask before recording you.

Per-site mic permissions are managed inside each browser:

• Safari: Safari → Settings → Websites → Microphone. Lists every site, lets you change to Allow / Deny / Ask.
• Chrome: chrome://settings/content/microphone. Allowed and Blocked lists, both editable.
• Firefox: about:preferences#privacy → scroll to Permissions → Settings… next to Microphone.
• Arc: Inherits Chrome’s permission model. Find similar at chrome://settings/content/microphone in Arc.

If you ever clicked “Always allow” on a website asking for mic access, it’s in the browser’s allowed list and will use the mic without re-asking. Audit those lists too.

Apps that often shouldn’t have mic access anymore

Common over-permissioned apps:

1. Old podcast or transcription tools you tried briefly
2. Note-taking apps with voice memo features you used once
3. Screen recorders that needed audio for one project
4. Communication apps you’ve stopped using (Skype after switching to Zoom, etc.)
5. “AI assistant” apps from a year ago that needed mic for voice queries
6. Translation apps with voice input you never use
7. Game launchers with voice chat features you don’t use

Toggle off generously. Re-enable later if you actually need them.

Apps that genuinely need persistent mic access

Some apps need mic permission constantly to do what you want them to:

• Video conferencing tools you actively use (Zoom, Teams, etc.)
• Voice control / dictation accessibility tools
• Dictation in macOS itself (System Settings → Keyboard → Dictation)
• Music production apps for live recording
• Streaming software (OBS, Streamlabs)
• Voice memos for journaling

These should stay on. The point of the audit is to remove unnecessary access, not all access.

Stale entries from uninstalled apps

If you uninstalled an app weeks or months ago, its entry in the Microphone permission list might still be there. macOS keeps entries to remember choices in case you reinstall.

Stale entries with permission off are harmless — there’s no app to use the access. Stale entries with permission on are also functionally harmless (no app to claim it), but cluttered.

To remove stale entries: select the app in the list, click the minus button at the bottom of the Microphone panel. You may need to click the lock icon and authenticate first.

If macOS doesn’t let you remove an entry, the app might still be installed somewhere on your Mac. Search Applications and other locations to confirm.

The orange indicator: trust it

macOS shows an orange dot in the menu bar whenever an app is using the microphone. Click the dot to see which app. This is reliable — it’s a system-level signal that apps can’t suppress.

Things to know:

• The dot stays on briefly after the mic is released, which is fine
• During phone calls (Continuity calling), the dot is on
• Web video calls turn the dot on/off as expected
• Some menu bar apps (clipboard managers, screen recorders) might briefly trigger the dot if they have mic access for some optional feature

If you ever see the orange dot when no app should be using the mic, that’s worth investigating. Click it, see the app name, decide whether you trust that app to be listening.

Microphone privacy beyond app permissions

A few related considerations:

• AirPods and external mics: app permissions cover any audio input, not just the built-in mic. AirPods, USB mics, audio interfaces — all flow through the same permission system.
• Continuity camera with iPhone mic: when using iPhone as a Mac camera via Continuity, the iPhone’s mic can be used too. Same permissions apply.
• HomePod / Siri activation: Hey Siri uses the mic for activation phrase detection. Different system, different controls. System Settings → Apple Intelligence & Siri.
• Voice Control: powerful accessibility feature that uses the mic constantly. Off by default. System Settings → Accessibility → Voice Control.

For most users, the standard Microphone permission audit covers what matters.

Per-site browser mic audit specifically for video calls

Chrome, Safari, and Arc users who do video calls in the browser end up with persistent mic permission for sites like meet.google.com, zoom.us, whereby.com. That’s fine if you actively use them.

If you’ve switched away from a service (left a previous job, changed Zoom→Meet, etc.), prune the per-site list. Sites you no longer use shouldn’t keep open mic permission.

What this audit doesn’t cover

A few mic-adjacent privacy items that aren’t in Privacy & Security → Microphone:

• Spotlight Suggestions — your search queries can include voice input from Dictation. Manage at System Settings → Spotlight.
• iCloud sync of voice memos — System Settings → your Apple ID → iCloud
• Web sites’ history of mic access — only browser-internal, not OS-level

For most users, the OS-level Microphone audit is the thing that matters.

A routine worth keeping

Twice a year is plenty. Also worth doing after:

• Uninstalling apps in bulk
• Switching communication tools (Slack→Discord, Zoom→Teams)
• Major macOS upgrades (sometimes the permission system changes)
• Any time the orange dot lit up unexpectedly

The audit takes a few minutes. It’s the kind of maintenance that keeps your Mac’s privacy state accurate to who you are now, not who you were three years ago.

Sweep handles this audit in one screen — every app with every permission, mic included, with one-click revocation. The same scan also covers camera, location, files, and contacts permissions, so you can do all of them at once instead of clicking through System Settings category by category.
