If your third-party mouse feels rough on macOS — jumpy scrolling, dead side buttons, no real driver — LinguaX fixes it. LinguaX is a lightweight, native macOS mouse enhancement app that gives any USB or Bluetooth mouse trackpad-grade scrolling, real button and gesture mappings, and per-app behavior, all without installing a kernel driver.

It is under 5MB, fully native (no Electron), keeps every setting on your Mac (no account, no telemetry), and works as a lightweight Logi Options+ alternative. Alongside the mouse tools, LinguaX has a second core capability: it automates macOS input-source switching for multilingual users.
