How to Make Your Mac Play a Sound When You Plug in the Charger

Confirmation is a strange beast in the computing world. Sometimes you perform an action and wonder if what you did had any effect. Other times, a window will pop up alerting you to some obvious fact that you didn’t need to be reminded about.

Charging your device is one activity where a confirmation is appreciated, however. Everyone at least once has thought they were plugging in their phone at night, only to wake up and discover that it didn’t charge.

This is why the new MacBooks include a chirp when their USB-C charging cable is connected. For those whose charger requires some acrobatics to connect just right, this tone can lets you know for sure that you’ve got it hooked up properly. If you’d like to enable this sound on your own Mac, you can follow these quick steps to do so.

You’ll need to open a Terminal window by pressing Command + Space to open Spotlight, then typing Terminal. Next, paste in the following command to enable the chime:

defaults write ChimeOnAllHardware -bool true; open /System/Library/CoreServices/ &

If you turn on the sound and decide you don’t like it, it’s easy to disable. Head back to the Terminal and use this command to reverse it:

defaults write ChimeOnAllHardware -bool false;killall PowerChime

Using this, you’ll have audio confirmation, plus the light on the charger, to confirm that everything is connected. That should suffice for any device!

Now that you always know when it’s charging, it’s worth taking the time to maintain your MacBook’s battery.

Do you appreciate this chime? Let us know if you’ve ever accidentally forgotten to charge your computer properly in the comments!

    What's the problem with checking the green/orange light on the charger itself?

      My 12" MacBook has no such LED indicator on the cable or the adapter. This helps out just nicely!

        This is one use case I had in mind for this. Glad it helps you, Raphael!
