There’s a difference when you want to use your mouse scroll wheel and your MacBook’s trackpad. I use my MacBook Pro as my main computer, connected to dual monitors and external keyboard and mouse. When I disconnect from all that, I use its keyboard and trackpad. And I want to use the trackpad different(ly).
When I spin the mouse’s scroll wheel down, I prefer the window contents to go downward. When I use two fingertips and swipe upward, I prefer the window contents to also go downward. It’s just natural to me, and it keeps my muscle memory in line with my required usage of Windows.
Apple disagrees. If you set the trackpad for natural scrolling, it also sets it for your mouse. You know, for convenience… In other words, macOS prevents you from mixing these settings even though they are separate settings. Grrr.
Scroll Reverser is the solution. The settings are simple. Then use your mouse the way you want, and then use your trackpad the way you want.
And Scroll Reverser is free.
