Overview
Mac Mouse Fix transforms any standard $10 three-button or multi-button mouse into an Apple Trackpad-grade navigation device on macOS. Featuring buttery-smooth inertial scroll momentum, Mission Control / App Exposé gesture emulation, Space switching via button drags, and zero external kernel drivers, it delivers crisp native ergonomics.
How It Works
Mac Mouse Fix operates through structured, deterministic execution stages:
Modern Trackpad Gesture Simulation: Maps third-party multi-button mice and middle-clicks to Mission Control, App Exposé, Look Up, and smooth desktop swiping.
Inertial & Accelerated Smooth Scrolling: Eliminates coarse stepped wheel ticks by synthesizing fluid, pixel-accurate Apple trackpad momentum curves.
Per-Application Remapping Rules: Adapts button modifiers, pinch-zoom triggers, and drag-to-scroll actions dynamically based on the active window.
Zero-Driver Quartz Event Tap: Intercepts HID events securely in userspace through Apple's CoreGraphics Event Services with complete privacy.
Key Technical Features & Capabilities
Smooth Trackpad-Grade Scrolling: Rewrites stepped physical mouse wheel pulses into fluid, variable-momentum pixels mirroring Magic Trackpad inertia.
Gesture Simulation on Standard Mice: Hold and drag side or middle buttons to glide smoothly between Mission Control, App Exposé, and macOS Spaces.
Rich Button & Modifier Remapping: Remaps mouse buttons 3-32 and click-and-drag gestures independently per keyboard modifier (
⌘, ⌥, ⇧, ⌃).Lightweight Helper Architecture: Runs all HID event capture via Apple's Accessibility and CoreGraphics Event Services with ultra-low background CPU usage.
