Mac Mouse Fix
Trackpad gestures, mapped onto a third-party mouse

Buttons and the wheel become configurable triggers for Mission Control, desktop switching, and smart zoom.
Open-source mouse customization that maps trackpad-style gestures (Mission Control, desktop switching, smart zoom) onto a third-party mouse’s buttons and wheel. Pairs with LinearMouse — that one tunes the cursor, this one tunes the gestures.
The middle button can summon Mission Control, side buttons can switch desktops, modifier-plus-wheel can zoom or page-navigate. Smooth scrolling is reimplemented to match the trackpad’s momentum, so wheel scrolling stops feeling jagged compared to two-finger swipes.
A single menu-bar app, no kernel extension, no helper services. Free, donation-supported. macOS 11+.
