Game not starting

Now it says "You cannot open the application "The Sims 4" because it may be damaged or incomplete.

Ok. It may be corrupted. Can you right click on it in your Origin Games Library and select Repair Game?

It won't even come up in my game library

The same screens that came up before are back, but now there's a big white x around the sims 4 when I try to open it on spotlight search

@emmyxsims

Can you post a screenshot?

Please can you also provide more information about your Mac. Instructions on how to do so here - http://answers.ea.com/t5/The-Sims-Mac/READ-FIRST-Sims-4-Mac-Help-Guides-and-Troubleshooting/m-p/4612396/highlight/true#M162

I restarted my computer and the sims 4 is showing up in my game library again so I'm repairing it, if that doesn't work I'll send you the screenshots

Hi, I'm sorry I've been super busy lately so I haven't been able to reply. My brother said I should try opening the game through finder and when I tried it said that the game may be damaged or incomplete. 

So I decided to move the sims to my desktop to open it and my ENTIRE game has restarted and I'm freaking out, all of my packs have restarted, my entire game, and my custom content. I don't care that much about the game it's just I would like to keep my custom content since I liked the items I had in it

Why did you move it to the Desktop? The Sims game icon should be in your Applications folder. Your game data - saves, CC etc. is in the Sims 4 folder in Documents > Electronic Arts. If you have moved out that Sims 4 folder to your desktop then the game will start as new again and create a new folder in Documents > Electronic Arts. Your previous saves, CC etc. will be in the folder you moved.

My friend had a very similar problem and that worked for her and many other people I have seen but it actually helped cause it created a new mods folder for my game so I moved my custom content into that folder and my game is now working
