Re: [READ FIRST] Saves, CC/Mods or Library items disappeared? iCloud issues
You need to change your preferences in System Preferences to save your game to your Documents folder located on your hard drive. I turned off saving to iCloud and everything now saves correctly to my Mac's hard drive. Once you change this, start up your game and allow a new Sims 4 folder to generate on your hard drive and then you can move your saved games from the Cloud to your computer. And yes, saving to the Cloud or another hard drive does slow down the response time of the game and can cause problems like corrupted game files much faster than if it is saved on your computer directly.
