By default, your MacBook Air trackpad is set to scroll in a “natural” direction (scroll up to move the page up and scroll down to move the page down). Some people prefer to scroll the opposite direction.
- Open System Preferences
- Click on Trackpad system preference
- In the Scroll & Zoom tab, uncheck Scroll Direction: Natural
Secondary Click (or a right-click)
The default settings is a two-finger click, but this can be changed to the bottom right or bottom left corner from the Point & Click tab.
Tap to Click
This setting allows you to tap to select rather than click. You can also change the firmness of the tap/click and the tracking speed.
