Indie Developer Releases $3 Mac App to Mitigate Pet-Induced Keyboard Errors

Indie developer Todd Alexander has released Cats Lock, a $3 application available on the Mac App Store, designed to prevent accidental keyboard inputs caused by pets. The utility addresses a frequent operational disruption for Mac users, specifically where cats walk, sit, or sprawl across laptop keyboards, resulting in unintended character entries. The app was released on the weekend preceding May 17, 2026, and is compatible with devices running macOS 14.0 (Sonoma) and subsequent versions.

The application provides users with a mechanism to quickly secure their input devices, either through a single click in the menu bar or via a designated keyboard shortcut. This functionality blocks all typing activity when there is a risk of interference from animals. Alexander’s development focuses on a straightforward solution to a niche but widespread problem, allowing users to maintain control over their devices without interrupting their workflow.

Cats Lock includes several features aimed at managing pet interactions and user discretion. The app offers deterrent sounds, including a pre-set warning tone and the option for users to record custom audio. Additionally, a Stealth Mode allows the application to run without visual overlays or audible noises, ensuring it remains unobtrusive during activities such as video playback, reading, or professional meetings.

The software also incorporates auto-unlock functionality, which disengages the keyboard lock when the screen enters sleep mode. This feature ensures that users do not need to manually re-engage the security measure upon waking their device. The combination of manual controls and automated responses aims to provide a seamless experience for users managing multiple pets or varying work environments.

While the source material describes the utility as a solution to a "very specific, but very common problem," it notes that the app’s effectiveness relies on individual user experiences. The release represents a targeted entry into the macOS utility market, leveraging the widespread ownership of Mac devices by pet owners. No data regarding download volumes or long-term stability metrics is currently available.
