Works perfectly. Make both files executable: Check if any hooks already exist these will be overwritten, so make sure it is OK for you sudo defaults read com. Add hooks for muting sudo defaults write com. So in order to do a very simple thing one needs an advanced degree in computer science… I thought Macs were easy to use….
On my MBP all I have to do it turn down the volume of the built-in speakers while in MacOS X, which is different from the volume of the headphone jack that I use all the time. Then select back the sound output device you were using or plug in your headphones.
As someone with an advanced degree in computer science I must have missed the day when we covered basic shell scripting. Oh that right shell scripting is not computer science… that must be why it was not covered.
How to Temporarily Disable the Startup Sound
Then again, props to you for chiming in with an unrelated post about your academic achievements. Not a good idea. The boot chime actually means something when doing diagnostics. Again LOL. All the information needed is output via the diagnostic port. The dong is just branding. A diagnostic tool that is rendered useless by muting the sound before rebooting would be pretty stupid. I have a MBP running I cannot mute or change the startup sound level from what it was set to last.
How to permanently turn off your Mac’s startup sound
Next thing Apple is going to take away the power button because, of course, we Apple zombies never want to turn off our devices! Thank you for getting to the point.
This commentary is almost as annoying as how complicated it is to do something that should be very easy. I thought Macs were user friendly. At least, it was while Steve Jobs was alive. That comment is true. Apple should reverse it and allow the sound when something is wrong with it, which is almost never. Thank you. Weird thing is that after using this command my mac is restarting and booting slower than befor: I hate that chime…i usually work till late…but in any chance if i had to restart the mac everytime when i restart this wakes everyone who is sleeping…why cant it be played in ear phones when ear phones are pluged…oh god apple give option to disable it or simply played through ear phones….
Thanks a lot for the info. I have been trying to find a solution for hours. Btw, it works very well on Mavericks. Evidently, the apple people themselves cannot mute this expletive deleted sound.
Want an easy way of disabling the startup sound?
Well, it was very loud in the store and I did not hear any boot chime there, but when I got home and turned the machine on the sound was still there, but lower in volume. I have never before heard this annoying sound when mute was activated. After the Pram reset, which in addition to resetting whatever it was supposed to, scrambled my desktop, magnified the whole screen AND THEN made that idiotic sound immune to the mute button!
Apple geniuses could not remove that sound or mute it. Well, the thing that worked for me was a download from arcana research. None of the other stuff worked. Imagine if you live in a crowded apartment. Its real late at night. You need to turn on your computer. Imagine if that happens in a high crime area at night. This does work in OS X Mavericks on any Mac, check your syntax to be sure you are properly entering the command. Off topic: How do you stop the Windows systems from chiming on startup?
You just go into your theme settings and disable system startup sound. It was also easy to do on an older mac. Terminal commands to disable a sound is rather extreme, I too dislike the startup chime. Out of the box a mac is arguably easier than Windows PC. However, when it comes to diverse budget range for notebook computers, Windows OS is more available. One may be willing to save hundreds of dollars instead of get aesthetics and a dramatized linux shell. How did you do to get rid of this horrible branding starting sound? Lots of opinions no real answers for a basic function.
Fortunately there is an article with details on exactly how to turn off the boot startup sound on any Mac:. Hmm, well the answer seems to vary from machine to machine and osx version as well. Eventually used. I dual boot ubuntu and osx and neither system detected the card until i removed the variable with the -d option. I turn on my macbook air to work when my toddler is sleeping and have woken him several times. Hi guys, I have been fighting with this stupid startup chimes and none of the terminal commands worked for me.
Now I have tried AutMute from app store and it works. Name required. Mail will not be published required. All Rights Reserved. Reproduction without explicit permission is prohibited.

Cocktail then obligingly reset the volume to the default value!
There were no other sounds in their place — the machines simply booted up and worked as appropriate — at least as far as could be told, no big deal. However, the machines eventually did need to be replaced: Till then, I will now silently cheer when I hear them. I checked that earlier today, but it shows that checkbox NOT used. Still, I think that may have been the app I used many years ago to disable it.

Indeed it kills the startup sound. And now my family is not upset or complaining about that Apple chord startup sound. Cocktail killed my entire sound system. Now what??? I got my first Mac about a year ago and this was my first project, getting rid of that annoying startup sound.
How to Disable the Mac Boot Chime Completely
At one point I seriously considered cracking the case and clipping the speaker wires. That did the job without any drama or third-party software. Does the nvram approach outlined above preserve the previous sound level setting or does it set it to zero every time you reboot? The very first time it set the sound level to zero which as i noted above i thought Cocktail had somehow destroyed my internal sound system.
Although perhaps they did provide a paper on why and what the three chord song is telling me. These days the base Unix OS itself and the high end commercial software used to defrag directories , repair permissions which always seems to be out of whack or repair hard drives and what ever other types of software one can buy all seem to preempt what ever it is that chord is telling me.
Still love Apple and especially their cryptic only Apple gurus can understand messages that pop up on my desktop and sit there for about a Milli second.
How to Mute Mac Startup Sound
Sometimes the problem is that the Mac is poorly built. I remember the fiasco Apple had with their Mirror door Macs and the flawed motherboards. There was something in the news recently about this sound. I think Apple was awarded a patent for it? I may be misremembering. Anyway, it was supposedly some sort of Zen thing. The sound that is, not the effect it apparently has on many of us. Mac startup sounds of the past:
