About:
Mos is a macOS utility that smooths scrolling animations across applications, eliminating the jittery feel of non-native scroll behaviors. It also allows users to independently set scroll directions for trackpads and mice, providing granular control over input preferences.

Key Features:

Smooths scrolling animations for a consistent experience
Independent scroll direction settings for trackpad and mouse
Per-application scrolling customization
Lightweight background operation with minimal resource usage

Use Cases:

Improving scrolling smoothness in non-native macOS applications
Configuring different scroll directions for external mice versus built-in trackpads
Creating a uniform scrolling feel across all software on macOS

Alternatives:

Scroll Reverser – Focuses only on reversing scroll directions without smoothing animations
LinearMouse – Offers mouse customization including scrolling but with different smoothing algorithms
