MiddleDrag

MiddleDrag adds middle‑mouse functionality to macOS trackpads by mapping three‑finger gestures to middle‑click and middle‑drag actions. A three‑finger tap generates a standard middle click, while a three‑finger drag produces a middle‑drag event that can be used for panning, orbiting, or scrolling in applications that expect a middle mouse button. The utility runs as a native menu‑bar app, works alongside existing system gestures such as Mission Control, and offers configurable sensitivity and smoothing settings.

The tool is aimed at users who rely on middle‑mouse input for web browsing, design, development, 3D modeling, or general productivity but lack a physical middle button on their Mac trackpad. It enables common workflows like opening links in background tabs, closing editor tabs, panning canvases in graphics programs, and navigating large documents without modifier keys.

MiddleDrag is distributed as an open‑source, free‑tier macOS application compatible with macOS 15+ and Swift 6.2+. It can be installed via Homebrew Cask, MacPorts, or a downloadable PKG installer, and it verifies download integrity through GitHub artifact attestations.
