How to Disable the Microphone on a MacBook

Your Apple MacBook has a built-in microphone that comes in handy when you want to record audio in certain applications. This microphone can also be used for dictation purposes on your system. If you’re using Microsoft Word or any other text document, you can use your microphone and dictate the words that you would like to appear on the document, instead of using your keyboard to type.

If you want to talk to a client, customer or colleague via video chat, you’ll need to use the built-in microphone on your system. However, if you end up leaving your microphone on accidentally, then it may pick up and record unwanted sounds on your computer. This can be quite troublesome. Luckily, you can easily stop the microphone from recording audio, by turning the volume all the way down. You also have the option to disable your microphone by switching the audio inputs.
