Disabling chime boot sound on imac

[Ransz]

So i tried disabling the chime sound on boot through terminal command because i switch a lot between os x and windows, but after a few times , the sound returns... Any idea how to perma disable it?

I can't figure it out. For me it's just way too loud. I don't know how to turn the volume down so that the chime boot is quieter.

How old is your iMac? AFAIK all Macs since about 2008 or so link the chime volume to the volume on OSX. So if your computer is on mute, your chime will not play.

I disabled the boot chime about 5 years ago and haven't heard it since. I use this http://www5e.biglobe.ne.jp/~arcana/StartupSound/BETA/index.en.html which adds a system preference. Another option seems to be a script you can get here: https://github.com/teored90/nobootsound

I just used the terminal command on here:

No need for the startup sound.
