Don't Touch is a unique Mac application designed to deter casual snooping and theft in public spaces like cafes. It transforms your MacBook into a vigilant alarm system. When activated, the app presents a calm screensaver. However, if anyone touches, moves, closes the lid, or unplugs your laptop, it triggers a loud siren, a red screen, and a series of vocal warnings. The alarm continues at full volume, even if someone attempts to lower it, until you return and enter your PIN. This tool is not intended as a high-security anti-theft device for determined thieves, but rather as a highly embarrassing deterrent for opportunistic individuals. It runs on macOS 13 Ventura or newer, supporting both Apple Silicon and Intel-based Macs. The application 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: touch, movement, lid closure, and charger disconnection.Forced full volume and blocked system controls (like closing windows or switching apps) while armed.Optional camera detection that only triggers if the entire laptop is moved, ignoring background activity.No recording or storage of camera data; the green light indicates it's active.A simple four-digit PIN for deactivation.A fallback option to hold the power button if the PIN is forgotten.No account, no cloud, and no internet connection required, ensuring privacy and offline functionality.A one-time purchase of $5, providing lifetime access to the app on all your Macs.The app aims to make taking your laptop the most awkward action in a crowded cafe, ensuring your device is safe during short breaks.
