MiddleDrag – three-finger trackpad gestures for middle button emulation

Summary: MiddleDrag enables middle-click and middle-drag actions on MacBook trackpads using three-finger gestures, addressing the lack of a physical middle mouse button required by professional 3D software. It integrates with system gestures like Mission Control without interference and installs easily via Homebrew.

What it does

MiddleDrag uses Apple's private MultitouchSupport framework to detect three-finger taps and drags, emulating middle mouse button clicks and drags on MacBook trackpads while preserving native system gestures.

Who it's for

It is designed for Mac users, especially CAD and 3D software professionals, who need reliable middle-button functionality without external devices or complex workarounds.

Why it matters

It solves the problem of missing middle mouse button support on Mac trackpads, enabling smoother 3D navigation without additional hardware or complicated setups.
