Ive used this one since Oct. 2016, first with Sierra and now later with High Sierra, and it brought back the startup chime that had disappeared to my 2015 MacBook Pro.

Mac models built after late 2016 do not have this sound effect on boot, except for the 2017 MacBook Air.

The only exception is MacBook Air (13-inch, 2017), which does have a startup chime.

Of course this leads people to the obvious question, can I enable a startup chime sound on the new iMac or macBook Pro but, currently, there is no proven or effective way of doing so.

The claim was that by launching Terminal app and entering the following command syntax.

You can execute that command on a new silently booting Mac, but it will not actually re-enable the startup boot chime sound effect on a Mac which does not support the startup chime sound.

Its possible that a method of re-enabling the startup chime will arrive sometime, but at the moment its not possible, and currently all new Macs do not have the sound effect on boot.

And thats why your new iMac or MacBook Pro is not making any sound effect on boot.

The MBA recovers the startup chime with the Terminal command string and the Mini does not.

I thought it might be something in the OS build that got rid of the sound file but it must be something else.

Its like pulling up to a McDonalds and learning they dont sell Big Macs anymore.

I was so lost without this iconic audio signature and must-have symbol of my Apple heritage.

No chime on startingso I googled the query Why No Chime I enjoyed the chime, as it reassured me the booting-up was underway.

The startup chime has existed since the very first Mac, why they removed it is a mystery too many.

I was wondering if Apple will ever bring back the startup sound for the newer Macs in a future update.

I hope so. Even better, have the option to enable or disable the startup sound.

I was wondering about that to, because I am completely blind, and use VoiceOver to navigate successfully on the computer.

I like the startup chime, because it helps me to know that the computer has turned on and is loading.

There is a command to use, if you want the Mac to play a chime when you plug in the power adapter.

Type this exactly: defaults write com.apple.PowerChime ChimeOnAllHardware -bool true; open SystemLibraryCoreServicesPowerChime.app.

This is part of it.

One more thing. If you decide to turn it off, and I recommend that you unplug the power adapter for both of these.

To turn off the sound when power adapter is plugged in, do the following command exactly: defaults write com.apple.PowerChime ChimeOnAllHardware -bool false; killall PowerChime.

Ive tried countless things to try and fix it, but still neither applications are working.

Identifiers saved there might be part of the authentication to IDS (iMessageFaceTime).

Make sure youve also enabled it in both the iCloud preferences as well as the Messages preferences.
