The iPhone and iPad have actually made an adorable little chime noise when plugged it into charge considering that their inception, however the Mac has no such noise as it utilizes the MagSafe light indications to show charging status. This changed with the brand-new 12-inch Retina MacBook which doesn’t have MagSafe so it makes use of the iOS chime noise to suggest charging. By default, this sound is merely handicapped for other Macs.
Nevertheless, there is a way to alter it so that any Mac laptop can make the chime by following a couple of simple steps making use of Terminal.
- Open Terminal.
- Type (or copy and paste) the following command into the Terminal console.
defaults write com.apple.PowerChime ChimeOnAllHardware -bool true; open/ System/Library/CoreServices/ PowerChime.app
Now, restart your Mac and let your power deplete below 100 %. Now, when you plug it in, you’ll hear the same renowned iOS chime noise. Charming.
The ‘‘ hack’ was highlighted on Reddit over the weekend however has existed ever given that OS 10.10.3 when the 12inch Retina MacBook was introduced. It also deals with the El Capitan betas. If you alter your mind and do not desire it any longer, you can simply turn it off again with the following Terminal command:
defaults write com.apple.PowerChime ChimeOnAllHardware -bool incorrect; open/ System/Library/CoreServices/ PowerChime.app
Now all your Macs can seem like your iOS devices when they charge! Note that this suggestion is clearly undocumented and future OS X updates might stop this from working. For now however, it’s been checked on OS X Yosemite 10.10.3 and later on as well as the current OS X El Capitan beta. [source]
