Fix Mic on Mac

Step-by-step macOS microphone troubleshooting

First, check if your mic is working:

🎤 Test My Microphone →

Step 1: Check System Settings

Click Apple menu → System Settings (or System Preferences on older macOS)
Go to Sound → Input tab
Select your microphone from the list
Speak — the Input level meter should move
If the meter doesn't move, the mic isn't being detected by macOS
Make sure Input volume is turned up (not all the way left)

Step 2: Check App Permissions

macOS requires explicit permission for each app to use the microphone.

Go to System Settings → Privacy & Security → Microphone
Find the app that can't access your mic
Make sure the toggle is On
If the app isn't listed, open it and it should prompt for permission
If you accidentally denied it before, toggle it off and on again, then restart the app

Step 3: Check Browser Permissions

If the mic doesn't work in a web app (Google Meet, web Zoom, etc.):

In Safari: Safari menu → Settings → Websites → Microphone → set to "Allow" for the site
In Chrome: Click the 🔒 lock icon in the address bar → Site settings → Microphone → Allow

Step 4: Reset NVRAM / PRAM

This can fix audio hardware detection issues:

Shut down your Mac
Turn it on and immediately hold Option + Command + P + R
Hold for about 20 seconds (you may hear the startup chime twice)
Release and let Mac boot normally
Note: On Apple Silicon Macs (M1/M2/M3/M4), NVRAM resets automatically. Just restart.

Step 5: Reset Core Audio

Restart the audio system without rebooting:

Open Terminal (Applications → Utilities → Terminal)
Type: sudo killall coreaudiod and press Enter
Enter your password when prompted
The audio system will restart automatically

Step 6: Check for macOS Updates

System Settings → General → Software Update
Install any available updates
Audio bugs are frequently fixed in point releases

Step 7: Create a Test User Account

To determine if it's a system issue or user profile issue:

Go to System Settings → Users & Groups
Create a new user account
Log into the new account and test the mic
If it works in the new account, the issue is with your user profile settings

Still Not Working?

Try a different mic or headset
Check if the mic works in Safe Mode (restart holding Shift key)
Run Apple Diagnostics (restart holding D key) to check for hardware issues
Visit an Apple Store or authorized service provider
