This wikiHow teaches you how to activate the built-in or external microphone on your Mac.
Step

Step 1. If desired, connect an external microphone via USB port, audio input port, or Bluetooth
- Most Mac computers (and all Mac laptops) have a built-in microphone. However, an external microphone will improve the sound quality of the recording.
- The available port configurations will vary depending on the Mac you have. Not every Mac has a sound input port, and some MacBooks have a single audio port that can be used as an input or output port. Check the sides and back of your Mac to see what ports are available on your Mac.

Step 2. Click the Apple menu in the top left corner of the screen

Step 3. Click System Preferences on the menu that appears

Step 4. In the middle right of the System Preferences screen, click Sound

Step 5. Click the Input tab at the top of the window

Step 6. Select a microphone
All microphones and audio input devices will appear in the menu at the top of the window. Select the input device you want to use.
- If your Mac has a built-in microphone, it will appear labeled Internal Microphone.
- If you don't see an external microphone in the list, check the microphone connection.

Step 7. Adjust the selected microphone settings with the controls at the bottom of the window
Slide the Input Volume switch to the right to increase the microphone sensitivity

Step 8. Test the volume by speaking into the microphone
Your voice will appear in the Input Level field. If you see a blue light in the Input Level field while speaking, your microphone is on.
- Uncheck the Mute box in the lower right corner of the screen.
- If the Input level bar doesn't light up while you talk, check the microphone connection, and adjust the volume.
Tips
- If using audio software along with an external microphone, you may need to change the software settings to select the audio input.
- Slide the Input volume button up to at least 70% for optimal sound recording.
