Do Not Disturb (DnD) is an open-source security tool designed specifically for macOS systems to monitor and detect unauthorized physical access to laptops. The tool operates as a background security monitor that alerts users when someone attempts to physically access their device without permission. It provides real-time detection capabilities for physical security breaches on Mac computers. DnD can be built from source code using Xcode or installed through a pre-built installer application. The tool includes both command-line functionality and a user interface application for installation and configuration. As an open-source project, the tool is available for free download and use. The development is supported through community contributions and optional financial support via the creator's Patreon page.
