Mouse drag on OSX

[GuruGurra]

Is there a difference between MouseMove and MouseDrag in OSX?

I hover over an item (e.g., a file in the explorer/finder) and execute the sequence:

robot.MouseDown()
robot.MouseMove()
robot.MouseUp()

On Windows, the item is selected, and when the mouse is moved, the item is moved with it.
On macOS, the item is selected, and when the mouse is moved, the item is left in place.
