A new Mac app called Cats Lock enables users to lock their keyboard instantly to stop cats from causing accidental inputs. Created by indie developer Todd Alexander, it offers quick access and deterrent sounds. The app is compatible with macOS 14.0 and later.

A new Mac app called Cats Lock, released this weekend, allows users to instantly lock their keyboard to prevent accidental inputs caused by cats walking over their devices, addressing a common pet-owner annoyance.

Cats Lock was developed by indie programmer Todd Alexander and is now available on the Mac App Store. It provides a one-click option from the menu bar or a customizable keyboard shortcut to lock the keyboard entirely, preventing any accidental keystrokes when cats are sprawled across the keyboard.

The app includes a feature to play deterrent sounds, alerting users when a cat steps onto the keyboard, with options to choose from preset sounds or record custom warnings. Additionally, it offers a ‘Stealth Mode’ that runs without visual indicators or noises, ensuring minimal disruption while in use. If the Mac’s screen sleeps, the app automatically unlocks the keyboard to avoid inconvenience. It is compatible with macOS 14.0 (Sonoma) and later versions.

Why It Matters

This app addresses a niche but widespread problem among pet owners who use Macs: cats interfering with their work or leisure by walking over keyboards and causing unintended inputs. By providing a quick, easy way to lock the keyboard, Cats Lock can improve productivity and reduce frustration, especially during meetings or while watching videos. Its deterrent sound feature also offers a novel way to discourage cats from approaching the keyboard in the first place.

Background

Pet owners have long dealt with cats walking across keyboards, often leading to accidental commands or disruptions. While some have used physical barriers or manual disconnection, these solutions are inconvenient. The release of Cats Lock aligns with a trend of niche utility apps designed to solve specific user frustrations on macOS. The app’s launch coincides with increased remote work and home computing, where pets frequently interfere with work devices.

“Cats Lock is a simple, effective tool for pet owners who want to prevent their cats from causing chaos on their keyboards.”
