Always on, through anything
Restart your Mac, wake it from sleep, or plug a keyboard back in — FastKey keeps Caps Lock instant automatically, and quietly double-checks that it stuck. You never have to lift a finger.
Caps Lock,
instantly.
Your Mac ignores quick Caps Lock taps on purpose — a hidden 75 ms delay buried in macOS. FastKey flips Apple's own switch, so every tap lands. Like it always should have.

You tapped it. macOS shrugged.
For years, macOS has held every Caps Lock press for a fraction of a second before it counts. Tap too quickly and the press is thrown away — no toggle, no light, nothing. It was meant to stop accidental brushes. It also eats the taps of anyone who types fast.
It's not your keyboard, and it's not your fingers. It's a setting deep inside macOS — and FastKey turns it off.
Don't take our word for it. Tap.
Two Caps Lock keys. The left one behaves exactly like your Mac right now — hold it under 75 ms and the press is swallowed. The right one is running FastKey. Tap both, fast, like you type.

FastKey includes this exact test for your real keyboard — ⇪ menu → Tap Test — so you can see the difference on your own Mac, any time.
Safe by design. Reversible in one click.
FastKey simply flips off the delay macOS puts on Caps Lock. It changes nothing permanent, installs no drivers, and never gets in the way of anything else you do.
- It can't break your Mac The change is temporary and lives only in memory. Restart without FastKey and your Mac is exactly as it was — always.
- Off in one click Turn it off from the menu and your Mac's normal behavior returns instantly. Uninstalling takes seconds.
- Signed & notarized by Apple Every release is checked by Apple's notary service, so it opens cleanly like any trusted Mac app.
- Private by default No accounts, no analytics, no tracking. FastKey never reads what you type — it only makes Caps Lock faster.
Set it once. Forget it exists.
FastKey keeps Caps Lock instant through everything — so you never have to think about it again.

Fair questions
No. The change is temporary and lives only in memory — nothing is written permanently. Restart without FastKey and your Mac is exactly as it was. The worst that can ever happen is that the delay simply comes back.
macOS requires that permission for FastKey to make Caps Lock instant and to run the Tap Test, which watches the Caps Lock key — and only that key. FastKey has no analytics and never reads anything else you type.
Caps Lock goes back to normal — nothing else changes, and nothing nags you on a timer. Buy a license (£4.99, once, 3 Macs) and it turns instant again. The Tap Test stays free forever, so you can always see the difference.
Yes — built-in, USB, and Bluetooth. FastKey keeps Caps Lock instant on every keyboard automatically, including ones you plug in later.
Not at all. Download it, open it, and Caps Lock just works. There's nothing to configure and no terminal involved — it lives quietly in your menu bar.
FastKey checks that it's working rather than assuming, and updates are free. If anything ever changes, the app tells you plainly in the menu bar instead of failing silently.
