I was cleaning my keyboard one day and sent a dozen emails in the process. So I built a small macOS app that locks all input while you wipe down. One click to lock, hold a shortcut to unlock.

It’s a stupid problem, but a surprisingly common one. You lift your laptop to clean underneath, your palm grazes the trackpad, and suddenly you’ve opened six tabs, activated Siri twice, and somehow entered a meeting you weren’t in.
I looked around for something that would just lock the keyboard and mouse temporarily - not sleep the screen, not require a password to unlock, just pause all input while I cleaned. Nothing did exactly that. So I built it.
WipeMode sits in your menu bar. Click it and it locks all input system-wide using macOS’s CGEventTap API - not just the app in focus, everything. An overlay goes up and your desktop blurs behind it.
To unlock, hold a configurable shortcut (default ⌘⌃U) for about a second. A progress ring fills as you hold - deliberate enough that a rogue swipe won’t trigger it, fast enough that it doesn’t feel like a chore. The shortcut and hold duration are both adjustable in settings.
The interesting part is the input blocking. macOS lets you create a CGEventTap - a system-level listener that can intercept and suppress keyboard and mouse events before they reach any application. That’s what WipeMode uses. It requires Accessibility permission, which macOS will prompt for on first run.
The app is built in Swift and SwiftUI, weighs under 1MB, and runs on macOS 13 and later. No telemetry, no network calls, no accounts. The source is on GitHub.

If something here resonated, I'd like to hear from you.

macOS gives you one option for login items — they all fire at once. I wanted some apps to wait. So I built a small SwiftUI app that staggers launches with configurable delays.
