Re: I can't find my sims 4 folder anywhere
The Sims 4 in your Applications folder and Launchpad is the actual game.
The Sims 4 in your Documents > Electronic Arts folder is your user data. This is where your saves are stored, in-game graphics settings, CC/Mods if you use them, and game cache files.
When you move the Sims 4 folder out of the Electronic Arts folder and launch your game it is forcing the game to create a new Sims 4 folder as it thinks you are launching your game for the first time. This is the first, and most important, troubleshooting step as user data can become corrupted resulting in a game which will not load.
