Block all keyboard input
Every keypress is swallowed while Clean Mode is active — letters, shortcuts, function keys, everything.
Toggle Clean Mode and all keyboard input is blocked instantly. Wipe your keys without triggering shortcuts, sending messages, or opening random apps.
Requires macOS 13 Ventura or later · Apple Silicon & Intel
Cleaning a MacBook keyboard while apps are open is a minefield — you bump a key, a shortcut fires, something unexpected happens. Synapse's Clean Mode blocks all keyboard input the moment you toggle it on. Nothing registers. Wipe away. When you're done, toggle it off and everything works again. It's the kind of tiny feature that makes you wonder why macOS doesn't ship it.
Every keypress is swallowed while Clean Mode is active — letters, shortcuts, function keys, everything.
Protect against accidental trackpad taps while you're wiping the surface.
Turn it on and off from the Synapse menu bar in a single click — no settings, no dialogs.
The Clean Mode tile turns blue and shows 'Input Blocked' so you always know when it's active.
No need to quit or hide anything. Clean Mode blocks input without affecting your running apps or windows.
Wipe aggressively, spray, whatever you need — nothing will fire while Clean Mode is on.
Click the S icon in your menu bar to open Synapse.
Click the Clean Mode tile in the Quick Actions grid.
The tile turns blue and shows 'Input Blocked' — keyboard input is now disabled.
Clean your keyboard and trackpad freely without anything triggering.
Click the tile again (mouse still works) to turn Clean Mode off.
