MacTap is a macOS menu-bar app that turns one, two, or three knocks on a compatible MacBook chassis or the desk beneath it into keyboard shortcuts and other mapped actions. It supports left- and right-edge layouts, configurable sensitivity and actions, presets such as Daily, Coding, Capture, Media, and Focus, and per-application overrides. Tap classification runs on-device, with gesture mappings stored locally and nothing uploaded. It requires macOS 14.6 or later and a MacBook whose motion sensor is exposed as an SPU HID device, including M2-and-later models and M1 Pro, Max, or Ultra systems; some M1 models, including the original M1 Air, are unsupported. The app requires Accessibility permission for actions to send shortcuts, is distributed as a signed and notarized macOS app, and is licensed under the MIT license.

Sonar is an experimental macOS app by Emanuel Perez that uses a Mac’s built-in speakers and microphone for camera-free hand-gesture control. It plays a steady high-frequency tone, typically 20 kHz, analyzes Doppler shifts in echoes reflected from the user’s hand, and maps detected movement to scrolling, swiping, and zoom commands. It includes calibration, practice demos, signal visualization, diagnostics, and support for other applications; microphone audio is processed locally in memory and discarded after processing. Sonar requires macOS 14 or later, supports Apple silicon downloads, and is distributed under the MIT license.

macTilt is a native macOS application that renders a 3D clamshell-fold animation as a MacBook lid closes. It reads the lid angle sensor and uses the live display, wallpaper, or other captured desktop content as the folding surface; the image remains fixed in space while the screen hardware moves through it, progressively blurring and fading to black. When the lid is open, the overlay is hidden and click-through, with no stated CPU or GPU activity. On Macs with a continuous lid-angle sensor, the animation follows the hinge angle directly; on machines with only a binary clamshell switch, it plays a time-based opening animation with an adjustable duration. The app uses Metal shaders, is written in Swift, supports Apple silicon and Intel Macs running macOS 14 or later, and requires Screen Recording permission to capture the desktop. It can also provide an interactive preview on desktop Macs, while external-display clamshell mode suppresses the hinge animation.

Mac Duo is a native Swift and Metal macOS app that makes desktop effects follow the position of a MacBook lid. It provides six transitions—Duo, Ghost, Roll, Shutter, Flex, and Iris—that animate the desktop around the hinge, including panel sliding, display curling, bowing, or iris-like closure. The app includes live preview, floating controls, menu-bar access, pause controls, and an option to clear the screen after the lid remains still. It runs locally without third-party runtime dependencies, accounts, analytics, or screen-content uploads; screen frames remain in memory when Screen Recording permission is enabled. It supports macOS 13 Ventura or newer on compatible Apple-silicon MacBooks, with an Intel preview for the 2019 16-inch MacBook Pro, and is distributed under the MIT license.

OpenLogi is a native, local-first desktop application and CLI for configuring Logitech mice, keyboards, lights, and UVC webcams without Logitech Options+, an account, or telemetry. Written in Rust with GPUI, it communicates with supported devices through HID++, UVC, Logi Bolt and Unifying receivers, Bluetooth, or wired connections. It provides button and F-key remapping, DPI presets, SmartShift controls, gesture bindings, device-specific settings, per-application profile overlays, webcam image controls, and plain-text TOML configuration; the GUI and CLI run on macOS, Linux, and Windows, although some profile and platform actions have narrower support. The repository states that the project is under active development and not yet stable.
