This small utility fixes macOS's unnecessary scroll acceleration. It runs in the background and allows you to scroll 3 lines with each tick of the wheel.

As of April 2024, this fix works on macOS versions 10.9–14.0.

You may download the binary here. It needs to be run each time you boot. If you want this to be automatic, do the following:

1. On macOS 13.0 and later, go to System Settings > General > Login Items; otherwise, go to System Preferences > Users & Groups > Login Items.
2. Add DiscreteScroll to the list.

If you want to undo the effect you may launch Activity Monitor, search for DiscreteScroll and force it to quit.
