How to Fix MacBook Microphone Issues

If basic troubleshooting doesn’t work, you might need more targeted fixes. Here are some methods worth trying:

1. Check Connections:
For external microphones, verify that they are properly connected. Remove and reinsert the plug. If using USB or Bluetooth microphones, ensure those devices are charged and connected.

Sometimes, the issue may lie within a specific app. Test your microphone in multiple applications (like Zoom, Skype, etc.) to see if the problem persists across the board.
