BetterMouse

The app provides macOS users with fine‑grained control over third‑party mice and keyboards. It delivers smooth, configurable scrolling with options for duration, direction and acceleration, as well as precise discrete scrolling and drag‑panning that works without a scroll wheel. Cursor speed and acceleration can be adjusted independently, and an on‑screen FPS counter shows real‑time performance. For supported Logitech devices it exposes hardware settings such as DPI, onboard profiles, vendor‑defined buttons and thumbwheel actions, and includes a tool for pairing unifying and Bolt receivers.

All mouse button events—including clicks, drags, holds and hold‑scrolls—can be mapped to keyboard shortcuts or custom actions, with support for modifier keys, click‑through, and multi‑shot behavior. Keyboard mappings cover general hotkeys, vendor‑specific functions for Logitech keyboards, and system‑level key‑to‑key substitutions. Per‑application profiles let users tailor scrolling, button and keyboard behavior for individual programs.

The utility runs as a menu‑bar app without installing extensions, drivers or agents, and it does not require registration or network access. It is Apple‑notarized, lightweight, and designed for low CPU and power usage. A seven‑day trial offers full functionality, after which a one‑time purchase provides lifetime access.
