Knock Overview
Knock is a unique macOS utility application that leverages the built-in accelerometer of Apple Silicon MacBooks to create a novel input method. Instead of using the trackpad or keyboard shortcuts, users can physically tap on the MacBook's chassis (the body itself) to trigger programmable actions. This transforms your laptop into an interactive device that responds to physical gestures, enabling instant access to common tasks and complex workflows directly from a simple knock, double knock, or triple knock pattern. It runs as a background utility, integrating deeply with macOS to execute commands seamlessly.
How to use Knock
First, download the Knock application from the official website. It requires macOS Sequoia or later and an Apple Silicon M2 or newer MacBook. After installation, launch the app and configure your desired actions. You can assign specific commands, application launches, macOS Shortcuts, terminal scripts, or system toggles (like mute audio or lock screen) to single, double, or triple knock gestures. The app uses a "Knock Test" tool to help you verify tap detection sensitivity before finalizing your setup. Once configured, you can simply knock on your MacBook's body to trigger the assigned action instantly, even through a desk surface.
Core Features of Knock
- Accelerometer-Based Tap Detection: Utilizes the MacBook's internal motion sensor to detect distinct knock patterns (single, double, triple) on the laptop chassis, not the trackpad.
- Programmable Gesture Actions: Assign custom commands to each knock type. Built-in actions include muting audio, locking the screen, taking screenshots, and toggling Focus modes.
- Command and Script Execution: Trigger the launch of any application, run custom terminal commands or shell scripts, and execute macOS Shortcuts automation workflows.
- Adjustable Sensitivity: Fine-tune detection sensitivity for lighter or heavier taps and includes automatic gesture suppression while typing to prevent accidental triggers.
- System Integration: Seamlessly works with macOS system functions and native Shortcuts app for comprehensive automation.
Use Cases for Knock
Knock is ideal for users seeking faster, hands-free control over their Mac. Quickly mute or unmute audio during video meetings with a discreet tap. Launch your most-used apps or documents without reaching for the keyboard. Program a triple knock to run a complex automation sequence that prepares your workspace. Developers can trigger terminal scripts or build processes. It's also useful for controlling media playback, toggling Do Not Disturb, or locking the screen when stepping away, all while maintaining focus on your primary task.
Advantages of Knock
Knock offers a tangible productivity boost by creating a new, intuitive physical shortcut layer. It eliminates the need to memorize keyboard shortcuts or navigate menus, allowing for instantaneous action execution. Its deep integration with macOS ensures reliable performance. The technology is clever, using existing hardware (the accelerometer) in a novel way. Being a lightweight utility, it runs unobtrusively in the background. The ability to trigger complex automations with a simple physical gesture can significantly streamline repetitive workflows for power users and professionals.
