Todd Alexander released Cats Lock on the Mac App Store between May 30 and May 31, 2026, offering Mac users a solution to accidental keyboard inputs caused by their cats walking or lounging on laptops [1].
The app allows users to quickly lock their Mac keyboard via the menu bar or through a keyboard shortcut, effectively blocking all typing when cats are present on the keys [1]. Cats Lock also features deterrent sounds, including warning noises activated when a cat approaches the keyboard, and users can record custom sounds to discourage feline interruptions [1].
A stealth mode runs Cats Lock silently without visual overlays or noises. This mode targets users engaged in video watching, reading, or meetings, where disruptions could be distracting [1]. Furthermore, the app automatically unlocks the keyboard when the Mac’s screen goes to sleep, ensuring users are not locked out during inactive periods [1].
Cats Lock supports macOS 14.0 Sonoma and later versions, aligning with Apple’s latest operating system requirements [1]. It is available as a one-time purchase priced around $3 on the Mac App Store [2, 1].
Engadget’s reviewer, who described themselves as a cat owner, praised the app as “kind of genius in a very silly way,” given the challenges cats pose by stomping over laptops [1].
With the launch completed over this past weekend, users can now download Cats Lock to protect their Macs from unintended typing caused by their feline companions.
