Apple's Magic Mouse now comes standard on most Mac models. By default, users may notice extreme oversensitivity when attempting to use the scroll function on the mouse to zoom in Vectorworks. To alleviate the worst of this problem, go to Apple > System Preferences > Mouse once the Magic Mouse has been paired with your machine and change the Scrolling option to "Without Momentum"
Once this is done, you should notice a dramatic improvement in scrolling behavior when drafting in Vectorworks.
