Introduction

Newer Mac Laptops have USB-C instead of MagSafe or MagSafe 2 for charging. When you insert your USB-C power adapter into your Mac Laptop with a USB-C port you will hear a charging chime that verifies your Mac Laptop is charging. Older Mac Laptops without USB-C do not have this function. You can enable this charging chime with this simple terminal command.

PS: The charging chime on the newer Mac Laptops is the exact same chime used on iPhones and iPads to verify charging on those devices too.

  1. Disconnect your MagSafe/MagSafe 2 power adapter.
    • Disconnect your MagSafe/MagSafe 2 power adapter.

    • Go to the spotlight search and search for Terminal. Open Terminal by double clicking it in the results area.

    • Paste the following command into the Terminal window and press enter

    • defaults write com.apple.PowerChime ChimeOnAllHardware -bool true; open /System/Library/CoreServices/PowerChime.app &

    • Terminal may automatically press enter for you. This may vary depending upon circumstances.

    • Done! Reconnect your MagSafe/MagSafe 2 power adapter and you should hear the charging chime

    • Your volume must be raised in order to hear the chime.

Conclusion

To disable the charging chime, simply change -bool true; in the command above to -bool false;

Hey there! You are able to turn off the chime by simply changing the command:

Turn on:

defaults write com.apple.PowerChime ChimeOnAllHardware -bool true; open /System/Library/CoreServices/PowerChime.app &

Turn off:

defaults write com.apple.PowerChime ChimeOnAllHardware -bool false; open /System/Library/CoreServices/PowerChime.app &

Difference is that the ‘on’ command states true and the off command states ‘false’

Try to attempt this, it may not work depending on your mac
