Sims game won’t stop loading…

Please help, I’ve been stuck on the loading screen for almost 3 days now and I have no idea what to do. I’m assuming it’s a storage issue because I recently bought another pack and im running everything on my Macbook + mods. I’ve tired to force quit and restart but nothing seems to work. I don’t even care about restoring what I was currently working on anymore, I just want the game to close!!! Please help!!
