Why?
Because the moment you step away is the moment something gets touched.
Coffee run
Your agents are mid-task. Lock it, grab a refill, come back to finished work.
The cat
She walks across keyboards. Now she walks across a glass square instead.
Tiny hands
The toddler wants to "help." Let them mash the trackpad, consequence-free.
Helpful coworker
Stop the over-eager teammate from "just fixing one thing" on your machine.
Bio break
Walk away from a long run without a lock screen swallowing the output.
Screen sharing
Present live logs and agents without anyone — including you — fat-fingering input.
Hot desk
Mark your machine "in use, hands off" while you're in a meeting nearby.
Petty revenge
Hand your laptop to the friend who rearranges your icons. Good luck.
How it works
Three keys. Zero windows in your way.
Hit the shortcut
Press ⌘⇧L from anywhere — or click Lock Now in the menu bar.
Input is sealed
Every keyboard and mouse event is swallowed system-wide. Your work keeps running, fully visible behind the glass.
Press ESC to release
Back in control instantly — or in Max mode, it locks your screen the moment you leave.
Built for people who leave the keyboard running
A tiny menu-bar app. No Dock icon, no clutter.
Two security modes
Low just blocks input. Max locks your Mac the instant you hit ESC — nothing gets through.
Every display
The lock covers all your monitors at once. The square follows your cursor across them.
Your words
Customize both lines of text, their colors, size and opacity — per light and dark mode.
Your shortcut
Pick any global hotkey to arm the lock. The default is ⌘⇧L; change it in seconds.
Official Apple Glass API
Built on Apple's native glass effect — the square looks like it belongs in macOS, because it's made of the real thing.
Open at login
Launches quietly with your Mac and waits in the menu bar until you need it.
Don't touch my Mac.
