Solution 2: Check for Pending Software Updates

To ensure that your macOS is up-to-date, go to System Preferences and select the Software Update option.

Install the latest update of macOS on your device and check if the issue was resolved.

Solution 3: Check the Sound Settings

Go to the Apple menu > System Preferences > Sound. Make sure that the Output tab is selected and that the correct audio output device is chosen. Try changing the output device to see if it resolves the “MacBook Pro speakers crackling” issue.

Your sound preference settings could also be the cause of the crackling issue. To check this, go to System Preferences, select Sound, and then choose the Sound Effects tab.

Solution 4: Review the CPU Usage

Ensure that your Mac is not overloaded by opening the Activity Monitor and selecting “CPU Usage” from the “Choose Window” menu.

This will help you determine whether your CPU is being overworked and causing the crackling. If the CPU usage is high, try closing some applications to see if it resolves the issue.

Solution 5: Reset NVRAM

Resetting the NVRAM (non-volatile random-access memory) on a MacBook Pro can help resolve issues related to the system’s settings, such as display resolution, sound volume, and startup disk selection. Here are the steps to reset NVRAM on a MacBook Pro:

1. Shut down your MacBook Pro.
2. Press the power button to turn it on and immediately hold down the Command + Option + P + R keys.

   

3. Hold these keys down for at least 20 seconds, until you hear the startup sound twice.

After resetting the NVRAM, you may need to reconfigure some settings, such as the display resolution or the startup disk selection. However, your personal data and files should not be affected by this procedure.

Solution 6: Kill the Core Audio Process

Core Audio service is responsible for managing and processing all audio on your Mac, including recording, editing, playback, compression, decompression, signal processing, and audio systems.

If you experience audio crackling issues on your MacBook Pro, force-closing this service may help resolve the problem.

To do this, you can execute a Terminal command, but keep in mind that you will require admin privileges for this to work.

Head to Applications> Utilities> Terminal.

Enter the following command in the Terminal window and press the Return key to execute it:

 

sudo killall coreaudiod

Enter your password to authenticate and proceed. Your device will now reboot automatically. Play any audio to check if the “MacBook Pro speakers crackling” issue was resolved after killing the Core Audio process.

Solution 7: Restart Mac in Safe Mode

To restart a Mac in safe mode, follow these steps:

1. Shut down your Mac completely by choosing Shut Down from the Apple menu or holding down the power button until the screen goes dark.
2. Press the power button to turn on your Mac and immediately press and hold the Shift key.
3. Keep holding the Shift key until the Apple logo appears on the screen. This means that your Mac is starting up in safe mode.

4. Once your Mac has started up in safe mode, you will see a login screen. Enter your username and password, as usual, to log in.
5. When you are finished using safe mode, you can restart your Mac normally by choosing Restart from the Apple menu.

Safe mode is useful for troubleshooting various issues with your Mac, such as starting up problems, software conflicts, or other unexpected behaviors. During safe mode, your Mac will only load necessary system extensions, so some features may be unavailable or not work as expected.
