Please bear with me. I am a recovering Windowsholic. My new M2 MacBook Air has the system tray (or whatever Apple calls it) at the bottom full of every app on the machine. Is there a way to clean that up so that it only displays apps that are actually running? I understand the little black dot shows active apps. But it is hard for me to deal with all that clutter. Or is this something that I will have to learn to "like"?
