Hi TheOriginalPatricio,
For help with your MacBook Pro microphone not working, we'd recommend walking through the following steps:
- Update your macOS to the latest version, 13.4.1: Update macOS on Mac
- Make sure there are no accessories (Bluetooth or otherwise) connected that could be interfering with the microphone input.
- Check your Sound settings.
- Open System Settings > Sound.
- Tap the Input tab.
- Make sure the MacBook Pro microphone shows and is selected.
- Make volume adjustments as needed.
If you don't see your MacBook Pro microphone listed to select at all, there may be a deeper issue. You can run an Apple Diagnostics to test the hardware on your Mac and identify any potential hardware issues.
