Looking for Guided Access?

A simple Guided Access alternative for Mac.

Keep a toddler from clicking away from a video, ending a family call, changing the volume, or typing into another app—all while the screen, sound, camera, and microphone keep working.

See how it works

One job. Done well.

Three steps to accidental-input peace.

No accounts, modes, or complicated setup. You choose the keys that unlock your Mac.

1

Choose an unlock sequence

Use any case-sensitive key sequence with one or more visible characters. It is a convenience, not a password.

2

Press Start

A clear five-second countdown gives you time to prepare before all pointer and keyboard input is blocked.

3

Type to unlock

Enter the exact unlock sequence. Every keyboard, mouse, and trackpad becomes responsive again.

What gets locked

Accidental input stops.
Your Mac does not.

⌨

Every keyboard

Built-in and external keyboards become inert.

◉

Mouse & trackpad

Clicks, scrolling, dragging, and gestures are blocked.

▶

Everything keeps playing

Calls, video, music, camera, and microphone continue.

Transparent by design

Your keystrokes never leave your Mac.

Mac Input Lock has no analytics, accounts, network access, background service, advertising, or telemetry. It remembers only enough recent characters to recognize your unlock sequence.

Why Accessibility permission?

Because macOS protects system-wide input.

Accessibility access lets Mac Input Lock observe and consume keyboard and pointer events. It does not grant access to your camera, microphone, files, screen, or internet—and the app requests none of those permissions.

Know before you lock

If you can’t unlock.

Test your unlock sequence before handing the Mac to a child. While locked, ordinary Force Quit controls are not practical because local input is intentionally blocked.

If the unlock sequence does not work, hold the physical power or Touch ID button until the Mac turns off, then restart. Unsaved work may be lost. The app will not automatically relock after restart.
