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.

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. Always envied those futuristic blips and bleeps the computers in cheesy cyberpunk movies make? sonorOS has you covered.

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 sonorOS to shout a warning that your MacBook needs charging when the battery level drops below 10%? Or how about telling it to play a sound to alert you as soon as Safari finally completes a lengthy download and deposits the file in your Downloads folder?

Perhaps you’ll load up your own grandfather clock sounds to help you keep track of the passage of time. You could set them to chime loudly on the hour while you contemplate the fragility of existence and the ephemeral nature of simple human pleasures.

Bored of the generic, anodyne Mac noises you’ve been listening to day in, day out for years? You can use sonorOS to play your own custom sound effects for any of these 36 system events – many of which are otherwise completely silent:
