Just a cool little trick to enable your macbook to Chime like iPhone when you connect power cable.

Here are the terminal commands:

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

defaults write com.apple.PowerChime ChimeOnAllHardware -bool false;killall PowerChime
