Hello, I just got a MacBook Air over the weekend and I'm already having an irritating problem. Seemingly at random, the cursor on screen will become only a highlight selector. I can't click on any elements of the UI- but if I move the cursor up and down it begins to highlight text on whatever window I was most recently using. I have been able to remedy this issue by connecting my Magic Mouse and right clicking or completely forcing the Mac to shutdown. I have tried closing the app most recently on screen by CMD-OPT-ESC, and have tried resetting the nvRAM, which did not help my issue at all. Am I causing some sort of user error? I am new to macOS so maybe I'm not doing something right. Also, the keyboard works so I can use tab and the arrow keys to navigate sort of. Closing the lid and waiting does not fix the issue. Thank you all for any help- it would be much appreciated.
