To personalize your Mac, you may like to change the color of folders from the default blue to a shade of your choice.In the new IOS Catalina, I cannot see my curser (pointer). If you drag the slider all the way to the left, that's the normal (default) size all the way to the right, that's the biggest size.
Now, you may move the Cursor Size slider to the right as far as you need, larger or smaller.
