Check if your Mac is connected to a power supply
If you're experiencing issues with the sound on your Mac, there are several troubleshooting steps you can take to identify and resolve the problem. One important step is to check if your Mac is connected to a power supply. Here are some detailed instructions to guide you through this process:
Check Your Connections
Begin by physically inspecting the connections between your Mac and its power source. Ensure that the power cable is securely plugged into both the wall outlet or power strip and your Mac's power adapter or charging port. Sometimes, a loose connection can cause power-related issues, so make sure all connections are snug and secure.
Identify the Correct Power Adapter
It's important to use the correct power adapter for your specific Mac model. Different Mac models may have different power requirements and connectors. For example, newer MacBook models often use USB-C connectors for charging, while older models may use MagSafe adapters. Check Apple Support or your Mac's documentation to identify the correct power adapter for your model.
Verify Power Adapter Wattage
In addition to using the correct power adapter, ensure that it provides the appropriate wattage for your Mac. You can usually find a certification label on the power adapter that indicates its wattage (in watts or W). If your Mac is connected to a power adapter with insufficient wattage, it may not receive adequate power, which could potentially affect its performance, including audio functions.
Check Power Adapter Functionality
If your Mac is connected to the correct power adapter with the appropriate wattage, the next step is to ensure that the power adapter itself is functional. Try using a different power outlet or power strip to rule out any issues with the power source. If possible, test the power adapter with another device to confirm whether it's working correctly.
Try a Different Power Adapter
If you have access to another compatible power adapter, try using it with your Mac. This can help determine if the issue lies with your original power adapter. Remember that you can use a compatible higher or lower wattage adapter without issues, but using an adapter with lower wattage than recommended may result in slower charging.
By following these steps, you can comprehensively check if your Mac is connected to a power supply and troubleshoot any related issues. It's important to ensure a stable power connection to maintain optimal performance, including sound functionality, on your Mac.

Check your Mac's sound settings
If you're experiencing issues with the sound on your Mac, there are several troubleshooting steps you can take to resolve the problem. Here are detailed instructions to help you check and adjust your Mac's sound settings:
Check Your Connections and Outputs:
First, ensure that your speakers or headphones are properly connected to your Mac. Check that the cables from your display or audio device are securely plugged into the corresponding audio ports on your Mac. If you're using external speakers, make sure they're plugged into a power supply and turned on.
Access Sound Settings:
Now, let's adjust the sound settings on your Mac:
- Click on the Apple logo () in the top-left corner of your screen and select "System Settings" or "System Preferences."
- In the System Settings window, scroll down and click on "Sound."
- In the Sound preferences, click on the Output tab.
- Verify that the correct output device is selected. Your Mac may have switched to a different audio device, so ensure that your preferred device (Internal Speakers, Line Out, or an external device) is highlighted or selected in the output device list.
Adjust Volume and Test:
Once you've selected the correct output device, adjust the volume settings:
- Drag the "Output Volume" slider to adjust the volume.
- If you're using external speakers, they may have their own volume controls, so check and adjust the speaker volume accordingly.
- If you're using Bluetooth headphones or speakers, go to System Settings > Bluetooth to ensure your device is connected. If it's not listed, put your device in pairing mode and click "Connect" when it appears.
Additional Troubleshooting:
If you're still experiencing sound issues, try these additional steps:
- Check for App-Specific Issues: Determine if the sound issue is specific to a particular app. For example, if you can't hear sound from a video in Safari, ensure the audio isn't muted within the video player.
- Restart the Sound Controller: Open Activity Monitor, locate the Core Audio controller ("coreaudiod"), and quit the process. Then, restart your Mac to reset the sound controller.
- Update macOS: Ensure that you're running the latest version of macOS. Go to Apple menu > About This Mac to check your current version. If updates are available, install them to potentially fix any audio-related bugs.
- Disconnect Peripheral Devices: If a USB device is selected as the output instead of the built-in speakers, disconnect all peripheral devices (such as headphones or external speakers) and try again.
By following these steps and checking your Mac's sound settings, you should be able to identify and resolve most sound-related issues.

Try using a different output device
If you're experiencing sound issues with your Mac, there are several troubleshooting steps you can take to resolve the problem. One potential solution is to try using a different output device, such as headphones or external speakers. Here are some detailed instructions on how to go about this:
First, ensure that your Mac is updated to the latest version of macOS. Outdated software could be the reason why your Mac is not playing sound through its internal speakers. To check for updates, click on the Apple menu and select "System Settings". Then, click on "Software Update" and install any available updates.
Next, disconnect any external output devices such as headphones or speakers that are currently connected to your Mac. This includes checking and disconnecting any devices connected to the 3.5mm headphone jack, USB or Thunderbolt ports, and HDMI ports. Once disconnected, try playing something on your Mac's internal speakers to see if the sound works.
If the sound is still not working, connect your headphones or external speakers back to your Mac. Go to System Settings, then click on "Sound" in the sidebar. Click on the "Output" tab and select your output device (headphones or external speakers) from the list. Make sure that your output device is properly selected and not muted.
If you're using Bluetooth headphones or speakers, you may need to take additional steps. Go to System Settings, choose "Sound", and then select the "Output" tab. Choose your Bluetooth device from the list of output devices. Make sure Bluetooth is turned on and your device is connected.
By following these steps and trying a different output device, you can troubleshoot sound issues on your Mac and determine if the problem lies with your internal speakers or something else. It's always a good idea to check your connections, settings, and alternative devices when encountering audio problems on your Mac.

Reset your Mac's PRAM
If you're experiencing issues with your Mac, such as strange behaviour from the clock, lights, battery meter, ports, or power button, then it may be time to reset your Mac's PRAM. PRAM (Parameter Random Access Memory) is the memory that stores core details about your Mac, including display settings, time zone, volume, and more. Resetting the PRAM can be a quick and easy solution to get your Mac back to normal.
To reset your Mac's PRAM, follow these steps:
- Shut down your Mac completely.
- Press the power button and, as soon as you power up the Mac, hold down Command-Option-P-R.
- Keep holding down those keys for about 20 seconds. If you have an older Mac that chimes at boot, hold down the keys until you hear a second startup chime.
- Let go of the keys and allow your Mac to continue starting normally.
- After your Mac has started up, go to System Preferences and check the Startup Disk, Display, and Date & Time panes to make sure they're set to your preferred settings.
If you hold down Command-Option-P-R at startup and only see a grey screen, don't panic. Wait for several minutes to see if anything changes. If you still don't see the Apple logo, a progress bar, or a second startup chime, try repeating the steps above or seek further troubleshooting advice.
Resetting your Mac's PRAM will return it to its default, factory values. This process is safe for your Mac and will not cause any harm. However, please be aware that any customisations you've made to your system settings may be lost, and you may need to reinstate some of your preferred settings.
