Don't Touch is a unique Mac application designed to deter casual snooping and theft in public spaces such as cafés. It transforms your MacBook into a vigilant alarm system.

When activated, the app displays a calm screensaver. If someone touches, moves, or closes your laptop, or disconnects the charger, it triggers a loud siren, a red screen, and a series of vocal warnings. The alarm continues at full volume, even if someone tries to lower it, until you return and enter your PIN.

This tool is not intended to protect against determined thieves. Instead, it serves as a highly embarrassing deterrent for opportunistic individuals.

Don't Touch runs on macOS 13 Ventura or later and supports both Apple Silicon and Intel-based Macs. It is a small, native app notarized by Apple, with no installation required.

Key features include:

* Menu bar integration for easy activation

* A calm screensaver mode when armed

* Detection of physical interaction, including touch, movement, lid closure, and charger disconnection

* Forced full volume and blocked system controls, such as closing windows or switching apps, while armed

* Optional camera detection that triggers only when the entire laptop is moved, ignoring background activity

* No recording or storage of camera data; the green light indicates when the camera is active

* A simple four-digit PIN for deactivation

* A fallback option to hold the power button if you forget the PIN

* No account, cloud service, or internet connection required, ensuring privacy and offline functionality

* A one-time purchase of $5, providing lifetime access on all your Macs

The app aims to make taking your laptop the most awkward action in a crowded café, helping keep your device safe during short breaks. It was developed by theill.
