First, make sure you have an updated version of macOS. If you are on macOS 10.12, please note that scrolling might not work for versions prior to 10.12.6.

In macOS 10.13, scrolling might not work for versions prior to 10.13.4.

If you’re trying to scroll using the mouse wheel, make sure that “Wheel” is set to “On” in the properties panel of the scroll component.
