Fix "MacBook Sound Not Working after Tahoe Update" Issue

Why Isn't My Sound Working on My Mac?

Before diving into the solutions, it’s helpful to understand the possible reasons why your MacBook's sound isn’t working after an update. The most common causes include:

  • The sound is muted, and you didn’t notice.
  • Your MacBook was last connected to Bluetooth and is still paired.
  • The volume is turned all the way down.
  • Peripheral errors.
  • Outdated macOS version.
  • macOS Tahoe bugs.
  • Wrong output device selection.

How to Fix Sound Not Working on MacBook

Now that you know the possible causes, let’s look at some practical ways to fix the issue.

It’s best to start with the simpler methods and work your way up to more advanced ones.

1. Check if Mute Is Turned On

In most cases, your MacBook speakers may not work simply because Mute is enabled. It’s common for users to turn Mute on and forget to turn it off.

Here’s how to check the sound settings on your Mac:

  1. Click the Apple icon in the top-left corner.
  2. Select System SettingsSound.
  3. Scroll down and see if Mute is enabled.
Check if Mute Is Enabled

2. Check if the Volume Is Turned Down

If the volume is turned all the way down, it may look like your MacBook has no sound. For example, you might lower the volume while taking a call and then forget to turn it back up.

To check, go to System SettingsSound and look at Output volume above Mute.

You can also check this via Control Center in the Menu Bar.
Check if You Turn the Volume to the Lowest

3. Check the Output Device

Your Mac may have more than one output device. If the wrong device is selected, you won’t hear sound from the MacBook speakers.

Go to System SettingsSound and check the selected device. If it’s wrong, reselect the correct device under Play sound effects through.

Alternatively, open Control Center in the Menu Bar, click Sound, and select the right device.
Check if You Select the Right Output Device

4. Check if Bluetooth Is Enabled

If your MacBook is still connected to a Bluetooth headset or speaker, sound will not come from the built-in speakers.

Wear your Bluetooth headphones to see if sound plays through them. If so, disconnect Bluetooth, and the sound should return to your MacBook.

You can disconnect Bluetooth in System SettingsBluetooth or via Control Center.

5. Restart the Sound Controller via Activity Monitor

Sometimes the sound controller may stop working properly. Restarting it through Activity Monitor often helps.

Here’s how:

  1. Open Spotlight and type Activity Monitor.
  2. Search for coreaudiod.
  3. Select it and click the X button to quit the process.
    Restart the Sound Controller via Activity Monitor
  4. Wait for the sound controller to restart automatically.

6. Restart Your MacBook

Restarting your Mac can fix minor glitches. If the above methods don’t work, restart your MacBook and check if the sound is back.

If restarting resolves the issue, it was likely a temporary error.

Tip
Some users report that freeing up memory with BuhoCleaner before restarting helped restore sound on their Mac.

7. Update macOS

An outdated macOS version can cause unexpected errors. Check your version under About This Mac or in System Settings. If it’s not up to date, go to Settings > General > Software Update to install the latest version.

8. Uninstall and Reinstall the Problematic App

Tip
Many apps have their own volume controls. Check the app’s volume settings before uninstalling it.

If a specific app is causing sound issues, uninstalling and reinstalling it may help.

Manual removal isn’t always thorough, so using a professional Mac cleaner is recommended.

BuhoCleaner is one of the best options for quickly and completely uninstalling problematic apps.
