The double-click variable above my mac cannot be selected, so it is very inconvenient to copy. How do you do it?

Problem analysis:

You can't double-click the selected word, either there's something wrong with your mouse (or you have a problem with double-clicking on your touchpad settings), or you have a problem downloading or installing, but I don't think the latter requires any steps and is less likely to go wrong. I prefer to believe that the former is the problem.

Solution:

Try another mouse.

Go to the touchpad settings to see the settings related to double-click.

Download and install again

Another situation is that the mouse double-click tracking speed is too fast, set a little slower on it.
