Zoom can't access the microphone on Mac: fixes in order of likelihood
Updated 2026-07-23
If Zoom says it can't access the mic (or you're just silent to everyone), it's almost always one of three things: the Microphone permission is off in System Settings, Zoom is set to the wrong input device, or Zoom hasn't been restarted since permissions changed. Run the checklist below top to bottom.
1. Check the permission
- 1
System Settings > Privacy & Security > Microphone.
- 2
Toggle zoom.us ON.
- 3
Quit Zoom fully (Cmd+Q) and reopen - permission is read at launch.
2. Check Zoom's own input device
- 1
In a meeting, click the arrow next to the Mute button.
- 2
Under 'Select a Microphone', pick your actual mic - not an output-only device or a virtual driver you don't use.
- 3
'Same as System' is the safe default; explicit AirPods selection stops working when they disconnect.
3. The AirPods trap
AirPods switch between devices aggressively. Mid-meeting they can jump to your iPhone, leaving Zoom capturing a mic that's no longer connected - you sound silent, no error shown. Turn off 'Automatically switch' in Bluetooth settings for the AirPods, or pick the built-in mic before important calls.
4. Input volume at zero
- 1
System Settings > Sound > Input.
- 2
Select your mic and check the input level meter moves when you speak.
- 3
If the slider is at zero, raise it - Zoom can't boost a muted OS-level input.
5. Reset a stale permission
After Zoom auto-updates, the mic grant can point at the old version. Reset and re-grant:
tccutil reset Microphone us.zoom.xos
Relaunch Zoom, grant the prompt, restart Zoom once more.
6. Another app has exclusive hold of the device
Pro-audio apps (or a stuck process) can hog the input device. Quit DAWs and other call apps, or unplug/replug the interface. A restart clears a wedged coreaudiod as a last resort - or run sudo killall coreaudiod (audio drops for a second, then rebuilds).
Frequently asked
Zoom shows 'you are muted' but I'm not - why can nobody hear me?
Zoom is capturing from a device that isn't your live mic (disconnected AirPods, a virtual device, an interface that's off). Fix 2 and 3: pick the correct input explicitly.
Why does Zoom lose mic access after every update?
macOS ties permissions to the app's code signature; some Zoom updates change it. Re-grant, or use tccutil reset for a clean prompt.
Do I need the Microphone AND Screen Recording permission for Zoom?
Microphone is required to speak. Screen & System Audio Recording is only needed to share your screen. They're independent grants.
