Introduction

Newer Mac Laptops have USB-C or MagSafe 3 instead of MagSafe or MagSafe 2 for charging. When you insert a USB-C or MagSafe 3 power adapter into a Mac laptop with those connectors, you'll hear a chime, indicating that the Mac laptop's battery is charging. Older Mac laptops without USB-C or MagSafe 3 don't have this function. You can enable this charging chime with a simple terminal command.

PS: The charging chime on newer Mac laptops is the same chime that's used on iPhones, iPads, and iPod touches to indicate charging on those devices.

    • 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.

    excellent. it worked exactly how it said after i raised the volume without having to restart

how to DISABLE THIS SOUND ? :)

Mars is flat too... -

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
