If you have a Mac, any mac, than you know that BOOOOOM noise, the chime noise, just that loud noise that goes off when you first turn on your mac. But theres a point where it gets annoying and you want to disable it but how? It`s actually really simple all you need to do is download the application Startup Ninja (http://www.allvu.com/index.php/products/startninja.html) and just follow the simple UI. First, enter your password to see your status than click OFF to turn the sound off and enter your password.
