How to Fix Audio Errors on a Mac

If your Mac has audio problems, or when you’ve selected a playback device that doesn’t have sound, apply a few quick fixes before taking it to Apple’s technical support (also known as Apple’s technical support). Genius Bar). Sometimes we just need to plug in and unplug the headset, the sound can also work again.

Note: This is a sign of hardware failure so you need to do this several times until it’s ok. Then, bring the computer to Apple service for a thorough repair.
Some users have reported that using Apple headphones makes the process more efficient.
