That’s the famous Mac startup chime, and like all technology, it has both good and bad aspects. On the good side, the chime tells you the Mac’s startup tests are complete and all is good. If the chime changes or doesn’t sound at all, then your Mac has a problem. What if you don’t want to hear the chime at all?
Silence Is Golden
If the Mac’s startup chime is a good thing, and it is, in what scenario is the chime not so good? For those of us who use the Mac’s chime and automatic startup time as an alarm clock, it’s a good thing.
Some Mac users would rather not hear the chime at all but Apple doesn’t build in an easy way to dispense with the chime’s distinctive sound. That’s what StartNinja does. This free utility gives you some control over the Mac’s built in startup chime. Install it, open it, click the setting to On, and the next startup arrives without the familiar Mac chime.
Caveats? Yes, a few. StartNinja doesn’t silence the startup chime on most iMacs, but works fine on all the MacBook Pro models in the Miller household. If you don’t mind spending a couple of bucks there’s the Silent Start app which does much the same thing (but doesn’t silent the chime if headphones are plugged into the Mac) but has a few more features, including Notification Center alert.
While silence is golden, remember, the Mac’s chime is there for a reason.
