I guess it’s a sign of my age. But I can’t stand that whole natural scrolling thing. So I disable it as a part of my imaging process. To do so, set the com.apple.swipescrolldirection global domain to false using defaults, as follows:
defaults write NSGlobalDomain com.apple.swipescrolldirection -bool false
To set it back:
defaults write NSGlobalDomain com.apple.swipescrolldirection -bool true
