Note the battery charging indicator will only display onscreen if there is less than 100% power available with the Mac battery and the Mac is either in sleep mode or the screen is locked. This may be helpful if you’re confused, or you just want to see what it does rather than try it yourself: The brief video below walks through entering the syntax into the Terminal app and then disconnecting and re-connecting a MagSafe adapter to trigger the power sound effect.

If you keep an eye on the battery and energy use menu of Mac OS X and you’ll see the sound triggers at the exact same time as the charging bolt appears on the battery menu item. You’ll hear the familiar power connected / charging sound effect from your iPhone and iPad devices. Now you just have to disconnect your MagSafe (or USB-C) power connector from the Mac, wait a second or two, then reconnect it. This will enable the feature through the defaults command string and simultaneously launch the PowerChime application, the latter tiny app must be running in order for the power chime sound effect to trigger.

Re-connect the MacBook power supply to hear the chime.

Enter the following command syntax, be sure there are no breaks as you’ll want to fit the entire sequence onto a single line (no it doesn’t matter if it wraps):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 a Power Chime Sound Effect on a MacBook Pro & MacBook Air This also requires Mac OS X Yosemite (10.10.3 or later) as the PowerChime.app does not appear to exist in prior releases of Mac system software. You won’t need to do this on the MacBook line because it makes the sound by default (though you can turn it off on that machine if you want to, more on that in a minute). Because the power indicator is dependent on a battery, this almost certainly requires a MacBook Pro or MacBook Air to function as intended. More insight in thread comments.Enabling the power chime sound effect on a Mac is pretty easy. May be a problem with adapter or cable as some have suggested. Issue is back, seemingly no fix as of yet. I'm not quite sure what the issue was, but it was and is concerning enough still, that I'll keep an eye out. Given this, I think everything is working as intended now, or at least much more reasonably, I would say. Also, I saw elsewhere that earlier MacBooks with MagSafe may have also quickly changed the indicated colour before staying solid when off. Plugging in when on immediately shows the correct solid amber or green light which I would still probably prefer to happen when off, but I can't say this is an issue as it is obviously much more acceptable behaviour than obnoxious flashing and noise.

Now, when plugging in when off, the adapter seems to take a moment to flash once between red/red or green, but remains correctly solid following that, without any power chime noise after the first.

Thankfully, after doing a full system erase, the flashing amber light and beeping are both gone.

Has anyone experienced the same? I don't think this is intended behaviour but if anyone knows more, it would be appreciated if shared. However, when the MacBook is off, the MagSafe light indicator continuously flashes amber to off to amber (etc.) every few seconds, while making the power chime sound every time. When on, charging seems to work as expected. I've already charged the device to 100% with no issues. This is my first Mac and I'm experiencing what I believe might be an issue, as I can't find any information about it online. I just received the new 2021 M1 Pro MacBook Pro 16' yesterday.
