Cats Lock Mac app exists because some pets treat an open laptop like shared property. The new macOS utility locks your keyboard and trackpad so a cat, dog or toddler cannot step across your Mac and turn a quiet afternoon into surprise emails, mystery shortcuts or a deleted paragraph.
Developer Todd Alexander launched the app on May 15, and the pitch is refreshingly simple. Cats Lock costs $2.99 once, has no subscription, requires no account and says it does not collect analytics or tracking data. It runs as a sandboxed Mac App Store app for macOS 14 or later.
A Small Fix for a Real Problem
The official Cats Lock press kit frames the app around pet chaos, but the use case is broader. It can also help when cleaning a keyboard, watching a video near a curious child or leaving a Mac open on a desk for a minute.
The app can play sounds, show an overlay and sit in the menu bar. The Mac App Store listing describes the lock shortcut as Command + Option + L, which is the safer detail to follow because app marketing copy can drift across a launch site and press kit.
The privacy posture also helps. A keyboard-locking app does not need cloud accounts, ad tech or a subscription dashboard. Cats Lock feels like the old-school Mac utility model in the best way: pay once, solve the annoyance and move on.
The Best Kind of Utility App
Cats Lock is not trying to become a platform. That is part of the appeal. It solves one goofy but common problem, charges a normal one-time price and stays out of the way. More small Mac utilities should be this honest.
