With sonorOS you can assign your own sounds to any of 36 common macOS system events. Customize alerts, modifier key presses, mouse clicks, window dragging and a whole lot more to play whatever sounds you like. Drag your .m4a, .mp3, .wav or .aif sound file onto an event in sonorOS and it will play every time that event occurs, for as long as the app is running unobtrusively in the background.

Always envied those futuristic blips and bleeps the computers in cheesy cyberpunk movies make? sonorOS has you covered. Tweak the noises coming out of your Mac to suit your tastes. Tinker to your heart’s content and create as many different sound profiles as you like, switching between them according to your mood.

In addition to injecting some personality into your computer, sonorOS can give you useful audio cues for important events that may happen when you've wandered away from your machine. Why not set it to sound a warning when your laptop's battery is perilously low, or play a sound to alert you when Safari finally finishes downloading a huge file?

These are the system events that you can assign custom sounds to in sonorOS:

An alert sound occurs
Battery needs charging
Clock strikes :00
Clock chimes the hour
Clock strikes :15
Clock strikes :30
Clock strikes :45
Safari download(s) begin
