Instant lock
Start protection in seconds and prevent unwanted clicks, keystrokes, or changes.
A native macOS utility
Screen Locker
Your screen stays on.
Your work keeps moving.
Block mouse and keyboard input without signing out or stopping what is running in the background. Built for children, pets, displays, and every moment your Mac needs to keep working untouched.
The problem
Not every lock should stop what is happening on screen
A video is playing, a download is moving, or an important process is running. One accidental click can disrupt it all, while the system lock hides your content and asks you to sign in again.
Screen Locker adds a simple protective layer over your Mac. Content stays visible and activity continues while mouse and keyboard input is blocked.
