One of the most common reasons for no sound on a Mac is that the volume is muted or turned down. It’s easy to accidentally mute or turn down the volume, especially if you’re using the keyboard shortcuts. To check the volume, click on the volume icon in the menu bar or use the keyboard shortcuts to increase the volume.

Audio Output is Incorrectly Configured

If you have multiple audio output devices connected to your Mac, such as headphones or external speakers, it’s possible that the audio output is configured incorrectly. To check the audio output, go to System Preferences > Sound and select the correct audio output device. You may also need to check the volume settings for each device.

Application Settings

Another reason for no sound on a Mac is that the application settings are configured incorrectly. Some applications, such as media players and web browsers, have their own volume settings that may be turned down or muted. Check the application settings to make sure the volume is turned up and not muted.

Hardware Issues

If none of the above solutions work, it’s possible that there is a hardware issue with your Mac. A faulty audio port, speaker, or cable could be causing the no sound problem. In this case, it’s best to take your Mac to a professional for repair.

Software Updates

Software updates can also cause issues with sound on a Mac. If you recently updated your Mac’s operating system, it’s possible that the update caused a conflict with the audio drivers. In this case, you may need to update the audio drivers or wait for a new update that resolves the issue.


Losing sound on your Mac can be frustrating, but there are multiple solutions to fix the problem. Check the volume settings, audio output, and application settings to make sure they’re configured correctly. If none of these solutions work, there may be a hardware issue or a conflict with a software update. Always make sure to backup your data before attempting any repairs or updates to your Mac.
