How to rearrange icons on the Dock
The Dock is very customizable, I already showed you guys how to add and remove icons from the Dock so today we’ll rearrange icons on the Dock so we have each icon in the order that we want.
From the Dock “Click, hold and drag” the icon to the spot you’d like and then release the click to drop the icon in place.
The only rule for moving icons around the Dock is applications stay on the left side and files/folders goes on the right side. If you look closely at the Dock you’ll notice a dotted line, this is the divider that keeps apps on one side and folders on the other.
