How to make your MacBook keyboard sound mechanical

A MacBook keyboard can't sound like a mechanical one by itself, and macOS has no keyboard click setting to turn on. What you can do is run an app that hears each key you press and plays a recorded switch at the same moment. Done well, with a different sound for the key coming back up and a little change from press to press, it's hard to tell from the real thing through headphones.

Koi 2.0 does it with 16 packs, from mechanical switches to a typewriter. For free, MechvibesDX is the open-source route. Klack is the well-known paid app, $4.99 once.

We make Koi, so read this with that in mind. Everything about Koi here is what version 2.0 does. Facts about other apps come from their own listings and READMEs, checked October 25, 2026.

1. Open Koi's Settings, then Notch & tools, and find Keyboard sounds. Or hover the notch, open the Tools and click Keyboard sounds.
2. Turn it on. It's off until you do.
3. Pick a pack. Each one types hello koi as you click it, so you hear it straight away.
4. Set the volume, then type anywhere: Mail, Slack, your code editor, a browser.

The 16 packs, in the order Koi lists them:

• Mechanical switches: Tactile (muted), Clicky (crisp), Linear (smooth), Brown (a tactile bump), Thock (deep), Alps (vintage) and Buckling (spring).
• Other keyboards: Retro (1980s), Office (rubber dome), Membrane (low profile) and Laptop (scissor keys).
• Typewriter, all metal.
• Just for fun: Toy (plastic), Pop (bubbles), Click (interface sounds) and Tick (soft).

Where a pack has one, the key coming back up has its own sound, and Space, Return and Delete sound like the bigger keys they are. Each press is a little higher or lower and softer or louder than the last, so a fast burst of typing doesn't turn into a drum machine.

• In password fields.
• For a key held down and repeating.
• For text Koi types itself.
• While you dictate, so your microphone doesn't hear clicks.
• On a call with Koi, while a call is recorded, and while a meeting app like Zoom has the microphone.

That last one matters more than it sounds. Your microphone hears the clicks your speakers play, so a keyboard sound app left on during a meeting can make you the loud typer on the call.

MechvibesDX is the official successor to Mechvibes, free and MIT licensed, with a curated set of sounds and custom packs. Its own README is honest about the Mac build, so go in knowing:

• It's for Apple silicon Macs only, and marked experimental and untested.
• It isn't notarized, so macOS blocks it the first time. You allow it from System Settings, Privacy & Security.
• It needs Accessibility and Input Monitoring. Without Input Monitoring it's silent whenever another app is in front.
• After an update you grant both permissions again.
• It sends one anonymous ping each time it starts.

The original Mechvibes still has a Mac download, but its last release was in December 2023, and “Mechvibes no sound on Mac” is a common search for a reason.

Klack's details are from its site and App Store listing. More options, including KeyClicker and Tapkey, are in the best keyboard sound apps for Mac.

• Headphones help. Through MacBook speakers the clicks sit on top of the real keys; through headphones they drown them out.
• Permission: every keyboard sound app needs Accessibility or Input Monitoring. You can see which apps have it in System Settings, Privacy & Security.
• Calls: turn sounds off before a meeting unless your app goes quiet by itself, as Koi does.
• Volume: start low. A loud thock gets tiring faster than you'd think.

Nothing beyond the sound. Koi hears each key going down and up through Accessibility only to play its sound at once. Which key it was is never kept, logged or sent. The packs are free-to-use recordings, built into the app and credited there, so nothing is downloaded either.

Koi has no free plan: Pro is $20 a month, or $7 for a first week. Lifetime is paid once. Keyboard sounds use no AI, so they never count against Koi's usage. If typing sounds are the only thing you want, Klack or MechvibesDX costs less. Koi makes sense if you'd also use its dictation, call recording or the rest. See the plans.
