Introduction

Mos is a free and open source macOS mouse wheel optimization artifact, specially designed to improve the scrolling experience of external mice on macOS, which can make the scroll wheel feel infinitely close to the silky and natural feeling of the trackpad, while retaining precise control, support macOS 10.13 and above systems, one-click installation or GitHub download through Homebrew,

support custom scroll curves (step, gain, and free adjustment of duration parameters), independent smoothing and reverse settings of horizontal and vertical axes, It is an indispensable lightweight efficiency improvement tool for Mac users who use external mice heavily, pursue a unified and personalized scrolling feel across applications, and are tired of the stiff scrolling of native mice.

Function

It is a free and open source macOS mouse wheel optimization widget, which specifically solves the problem of traditional mouse wheel scrolling stiff and not smooth on macOS, it uses intelligent smoothing algorithms, custom acceleration curves and axial separation, so that the scroll wheel feel is infinitely close to the silky experience of the trackpad, and at the same time supports independent configuration by application, shortcut key binding and other advanced gameplay, suitable for macOS 10.13 and above, becoming a must-have artifact for many users to improve the comfort of mouse use.

  • Smooth scrolling core algorithm: Transform the discrete increments of the original scroll wheel into continuous, predictable smooth motion, and easily adjust the step, gain and duration parameters to easily adjust the most comfortable scroll curve and avoid abrupt jumping sensations.
  • Independent control of the horizontal and vertical axes: Smooth and reverse scrolling settings can be enabled/disabled for vertical (Y-axis) and horizontal (X-axis) scrolling respectively to achieve finer feel customization and meet the needs of different scenarios.
  • Differentiate by application: Override global settings for each app individually, such as pursuing pixel-accurate scrolling in Xcode, maintaining the ultimate smoothness in Safari or Notion, and truly achieving “different apps feel differently”.
  • Real-time event monitor: Built-in device event monitoring tool, which can clearly view the original key and scroll wheel data emitted by the mouse, which is convenient for debugging and advanced customization.
  • Lightweight, free, and completely open source: The application is small in size, the resource occupation is extremely low, and it adopts an open source license, allowing users to freely view the code and participate in contributions.
  • Wide compatibility and long-term maintenance: Supports macOS 10.13 High Sierra to the latest version, and the developer continues to update to ensure stable performance on new systems and new mouse hardware.
