Turn the mouseinto flow.
Mos is a free, open-source macOS utility that makes wheel scrolling feel closer to a trackpad, without getting in your way. Tune curves, split axes, and override behavior per app.
Deterministic scroll. Tunable feel.
Mos turns raw wheel deltas into predictable motion. Keep the same feel across apps, and override it when you need to.
Smoothness is a curve. Adjust step, gain, and duration, and see how raw wheel deltas turn into controlled motion.
Treat vertical and horizontal scroll as separate axes. Toggle smoothing and reverse independently for each.
Let each app inherit defaults, or override scroll and button rules. Precision where it matters, smooth everywhere else.
Record mouse or keyboard events and bind them to system shortcuts. Use the live monitor to see what your devices are sending.
Download Mos. Tune your scroll.
Install in seconds, tweak it when you need to, and keep your scroll behavior consistent across the apps you live in.
