Many new MacBook owners have hardly noticed this feature, but the source of the audio was discovered by which reports that some Macs even have a vibrating trackpad with it feature enabled (a new Retina MacBook Pro doesn’t offer that aspect). This will turn off the sound effect when connecting a power cable to the MacBook Air, MacBook Pro, and yes, it will also turn off the sound effect of the power bell on the MacBook line. You can also turn off the power bell sound effect when connecting a power cable to a Mac by specifying a different default command string in the Mac OS X Terminal:ĭefaults write ChimeOnAllHardware -bool false killall PowerChime Use the following command to play the sound effect of the electric chime:Īfplay /System/Library/CoreServices/PowerChime.app/Contents/Resources/connect_power.aif Turn off the chime effect on the power cable connection in Mac OS X. You can also activate the sound effect manually, maybe you like the way it sounds or you are just curious what we are talking about here. The sound effect is triggered even when the MacBook is also sleeping, although that aspect seems limited to newer hardware with the ability to use PowerNap. Note that the battery charging indicator will only show on the screen when less than 100% power is available with the Mac battery and the Mac is in sleep mode or the screen is locked. This can be helpful if you’re confused, or if you just want to see what it does instead of trying it yourself: The short video below explains how to enter the syntax in the Terminal app and then disconnect and reconnect a MagSafe adapter to activate the powerful sound effect. If you keep an eye on the Mac OS X battery and power menu, you’ll see the sound triggering at the same time as the charging bolt appears on the battery menu item. You will hear the familiar sound effect of connected power / charging through your iPhone and iPad devices. Now all you need to do is unplug your MagSafe (or USB-C) power connector from the Mac, wait a few seconds, then plug it back in.

This will it feature via the standard command string and launching the PowerChime application at the same time, the last small app must be running to activate the powerchime sound effect.

Reconnect the MacBook power to hear the beep.

Enter the following command syntax, making sure there are no gaps as you want to fit the whole string on one line (it doesn’t matter if it wraps around):ĭefaults write ChimeOnAllHardware -bool true open /System/Library/CoreServices/PowerChime.app &.

Open the Terminal app, found in / Applications / Utilities /.

Disconnect the Mac from the MagSafe power source.

Enable playing Power Chime sound effect on MacBook Pro and MacBook Air This also requires Mac OS X Yosemite (10.10.3 or later) as the PowerChime.app does not appear to exist in previous releases of Mac system software. You don’t need to do this on the MacBook line as it makes the noise by default (although you can turn it off on that machine if you want, more on that later). Since the power indicator relies on a battery, this will almost certainly require a MacBook Pro or MacBook Air to function as intended.

Enabling the Power Chime’s sound effect on a Mac is quite easy.
