can someone help me with unity not responding on mac?

so Im trying the roll a ball tutorial to get some experience and every time i go to make the plane, i try to save the project so that its saved, I'm on an apple laptop and just want to make a little game for a high school project I'm working on. The problem is like i said i try to save after i set the plane and rename it ground from the tutorial and then the spinning wheel of death comes up, i go to the apple button since it has force quit and in the menu for the things you can force quit it says if something is not responding, it tells me that unity is not responding and i can't figure out how to fix it.
