Lock the keys. Love the cat. Cats Lock is a one-click keyboard lock for Mac, built for the moments your cat decides your laptop is the warmest spot in the house. Hit the lock, let her settle in, and get back to whatever you were doing without random typing, deleted documents, or a sudden trip to System Settings. ONE SHORTCUT, ANY APP Press ⌘L from anywhere — Safari, Mail, Notes, your terminal — and Cats Lock instantly blocks every key. A friendly overlay shows what's happening; the same shortcut releases it when you're ready. Prefer a different combo? Record your own in Settings. STEALTH LOCK FOR SLEEPING CATS When your cat is already settled and you don't want a visual takeover, flip on Stealth Lock from the menu bar or Settings. Same keyboard blocking, no overlay, no sound. LOCK THE FUNCTION ROW (OPTIONAL) Got a cat that loves the top row? Optionally block the function keys too (F1 through F12), including Mission Control, brightness, volume, and media keys. This feature needs Accessibility permission, so it stays off until you choose to turn it on. PICK YOUR FELINE DETERRENT Choose from six built-in sounds — including a spoken "Warning, cat on keyboard" voice prompt — or import your own. Sounds play on each blocked keystroke to help train your cat over time. Or stay completely silent. KEEP YOUR MAC AWAKE Optional setting keeps your Mac (and the overlay) awake while you step away, so you can come back to the same locked state hours later. LIVES IN THE MENU BAR Cats Lock stays out of your way. Always one click from the menu bar pawprint. Optional Hide from Dock for a pure menu bar experience. Optional Launch at Login. Auto-unlocks when your screen goes to sleep so you're never locked out of your own Mac. PRIVACY-FIRST Cats Lock runs entirely on your Mac. No accounts, no cloud, no analytics, no data ever leaves your device. The app is fully sandboxed and uses only standard Mac frameworks. The core lock needs no special permissions. The optional function-key locking feature is the only thing that ever asks for Accessibility, and only if you choose to turn it on. DESIGNED FOR CAT PEOPLE Made by a cat owner who got tired of his cat rewriting documents in real time. Every setting exists because a real cat needed it. REQUIREMENTS macOS 14.0 (Sonoma) or later. Apple Silicon and Intel Macs supported.
