My wife insisted on getting a Macbook Air a few years ago. I know very little about them and she knows just a little more than I do.

Her touchpad won't click anymore and the mouse won't move. From YouTube, I figured out how to turn on the keyboard mouse so she can now move the pointer around the screen with keystrokes, but it's super slow and horrible to use that way. Everything looks fine about the touchpad when I go to the System Settings. I can't figure things out from the online forums I've seen.

Do we just need to take it to a repair shop? If so, any recommendations out there? TIA
