Use an Apple wireless mouse
You can use the Magic Mouse and Magic Mouse 2 to interact with your Mac in much the same way you use the trackpad of a MacBook, MacBook Pro, or MacBook Air.
Using gestures, you can scroll long lists and webpages with one finger, swipe left and right with two fingers to navigate, and use screen zoom to make onscreen images larger.
You can also use the right or left side of the mouse as a secondary click.
Before using an Apple wireless mouse, you need to connect it with your Mac. See Connect an Apple wireless keyboard, mouse, or trackpad for more information.
Choose Apple menu > System Preferences, then click Mouse.
Select point and click options:
Scroll direction: natural: Select this option to move the contents of a window in the same direction as your fingers.
Secondary click: Select the option, then choose “Click on the right side,” or “Click on the left side” to secondary (or Control) click items on your screen.
Smart zoom: Select this option to double-tap with one finger to zoom in or out.
Select more gestures:
Swipe between pages: Select this option and choose “Scroll left or right with one finger,” “Swipe left or right with two fingers,” or “Swipe with one or two fingers” to move between pages in a document.
Swipe between full-screen apps: Select this option to move between apps in full screen.
Mission Control: Select this option to double-tap with two fingers to enter Mission Control.
