How to Fix Sound Not Working on Mac or MacBook

1. Check volume and mute settings

This may seem too simple, but sometimes the obvious is the most overlooked. Make sure the volume on your Mac is turned up and not muted.

1. Look for the volume icon in the menu bar at the top of the screen.
2. Click on it and adjust the volume slider.
3. Also, check that the "Mute" box is checked. If it is, uncheck it.

2. Check Output Selection

Sometimes, your Mac may have switched to an output device you didn't expect (such as external speakers or headphones).

1. Go to System Preferences >Sound.
2. Click the "Output" tab.
3. Here you should see a list of devices you want to send sound output to. Make sure "Built-in speakers" is selected.

3. Check sound settings in apps

Individual apps on Mac can also set their volume settings. Make sure the app's sound settings are correct. If you hear sound elsewhere but not within a specific app, check the sound settings for the app itself.

4. Restart your Mac

Often simple problems can be solved by simply restarting the system. If the problem persists, it's time to dig deeper.

5. Reset Stroller/NVRAM

Parameter RAM (PRAM) or Non-Volatile RAM (NVRAM) is a small portion of computer memory used to store certain settings in Locations that macOS can quickly access. Audio issues sometimes occur due to issues with these settings.

1. Turn off your Mac.
2. Press the power button, then immediately hold down the Option, Command, P, and R keys simultaneously.
3. Release the button after about 20 seconds. During this time, your Mac may restart.
4. If your Mac plays a startup sound, you can release the keys after the second startup sound.

6. Reset SMC (System Management Controller)

If the PRAM/NVRAM reset is unsuccessful, you can try to reset the SMC. This will control various hardware settings on your Mac.

1. Turn off your Mac.
2. If your MacBook has a non-removable battery:
   • Also hold down the Shift Control Options Power button.
   • Release all the keys at the same time, then turn on your Mac.
3. If you have a Mac desktop or MacBook with a removable battery:
   • Unplug the power cord, wait 15 seconds, then plug it back in.
   • Wait another 5 seconds, then turn on your Mac.

7. Update macOS

Updating your Mac may also solve your problem. Apple frequently releases software updates that fix potential problems with its systems.

1. Go to System Preferences >Software Update.
2. If an update is available, click the Update Now button.

8. Safe Mode

Start your Mac in Safe Mode to check whether the problem is caused by a cached data issue or a problematic application.

1. Turn off your Mac.
2. Press the power button, then immediately hold down the shift key.
3. Release the shift key when you see the login window.

Test the sound in safe mode. If it works, the problem may be due to a software conflict. Follow these steps: Restart your Mac to exit Safe Mode and find and uninstall recently installed apps.

9. Contact Apple Support

If none of the above measures work, then you may be facing a more serious hardware problem that requires professional repair. If you need professional help, contact Apple Support or visit an Apple Store.

Remember, if you are not a trained professional, do not open your Mac yourself as it may void your warranty and possibly cause more damage. Advanced hardware repairs are best left to the professionals.

These steps below should resolve most audio issues you may encounter on your Mac. It's best to start with the basics before moving on to more advanced steps, as the solution may be simpler than you think. If the problem persists, feel free to seek professional help.
