Not sure if you’ve ever slept around computers, but when you don’t remember to mute them… man, it’s annoying when in the middle of the night you hear an update sound or something that scares the living bajeebus out of you.
We’re talking, “WHOA! What the heck was that!” type of startling. Well, no more of that. You can sleep soundly knowing that your Mac won’t be waking you up with SoundAsleep. Just set the “night time mode” with hours and all, and sleep soundly.
