70 megabytes. That's the download size for a small Mac app whose entire job is to make your keyboard sound like a mechanical one. Klack isn't a utility trying to solve a dozen problems—it does one thing and does it with the kind of care you notice on the first keystroke.

Built with Swift and tuned for the Mac's audio stack, Klack uses spatial audio to place the sound around you—key presses land differently than key releases. The feedback is instant, so there's no lag between your fingers and your ears. Once it's running, it lives quietly in the menu bar, out of your way. No data collection, no personal information gathered. It's for people who miss the clack of a mechanical board but prefer the typing experience they already have, or for anyone who simply enjoys the sound.
Version 1.7.2 was a housekeeping update that made the app behave better in everyday use without adding anything flashy. The developer tightened up the audio engine so the typing sound doesn’t drift out of sync during long writing sessions—something you’d only notice if you spend hours in a text editor. Randomization of the key sounds also got a little smarter, so repeated letters sound less like a copy-paste job and more like a real switch under your fingers.
A few conveniences worth knowing about:
- You can swap switch sounds from the menu bar without opening a preference window—just hold Option and click the Klack icon to cycle through your installed switches.
- The spatial audio isn’t just a gimmick. If you wear headphones, key-down sounds sit slightly lower and closer than key-up sounds, which tricks your brain into hearing depth. It’s subtle, but once you notice it, turning it off makes everything feel flat.
- Klack plays nicely with Do Not Disturb focus modes. The sounds duck automatically when a call comes in or when you switch to a focus mode that silences system audio.
If you want to try different switch profiles, dragging a new sound pack onto the menu bar icon installs it without digging through folders. The app handles the rest.
- macOS 13.1 or newer
- Runs on both Apple Silicon and Intel Macs
