Teclo

Make your MacBook sound like a mechanical keyboard. Teclo is a small menu bar app that plays a sound for every key you press and release, in any app. Pick from 16 synthesized sound packs across five moods (Mechanical, Night, Retro, Arcade, Scifi), turn on mouse click sounds or a ding on Return, and watch a keycap pet type along: it sleeps when you stop and powers up when you keep the pace. Teclo hears the key, not the letter: no account, no server, no typing history. macOS 13 or later. USD 4.99 once for a lifetime licence on up to 3 Macs, with a 7-day free trial.
