TapNoisemacOS can provide click feedback through Slow Keys, an accessibility feature. However, Slow Keys also changes how long a key must be held before it is accepted. That makes it a different tool from a typing sound app.
What Slow Keys is for
Open System Settings › Accessibility › Keyboard to find Slow Keys and its options. Its acceptance delay is designed to change keyboard response, and click feedback helps indicate that response.
If you need that accessibility behaviour, tune it for your own use. If you only want a mechanical-style sound, enabling an acceptance delay may make normal typing feel unexpectedly unresponsive.
Keep keyboard response separate from audio
A sound app accompanies the key events that macOS delivers. It can offer different timbres and volume without deliberately asking you to hold each letter for longer.
There is still playback latency to consider, especially through wireless headphones. That is different from a setting that delays whether the key press itself is accepted.
Choose based on the actual need
Use Slow Keys when its input behaviour helps you. Use a typing sound app when you want an audio preference while keeping normal keyboard response. If you enable both, test the combined feedback carefully; two click layers can be confusing.
TapNoise’s demo lets you compare themes first. For a keyboard that suddenly seems slow, check Slow Keys troubleshooting before assuming a sound app or the hardware is broken.
