If you have CC/Mods installed in your game it is essential that you move them out of the Sims 4 folder before updating your game. To make sure you are not caught out by automatic updates, before you have a chance to move out your CC/Mods, you need to turn them off.
- To turn off automatic updates for your game, open Origin then go to Preferences:
Make sure you’re in the Application tab and scroll down to Client Update. Automatic game updates and Automatically update Origin should both be off:
- Make sure Origin is not automatically loading when you start up/login to your Mac. Automatically start Origin should be off:
- To verify that Origin shouldn’t be loading at startup/login you can double check whilst it’s open. Right click on the Origin icon in your Dock, go to Options and make sure Open at Login is unticked:
- And finally, to triply make sure Origin shouldn’t be loading at startup/login, check your user account preferences. Open System Preferences then click on Users & Groups:
Make sure your user account is selected then click on Login Items in the right hand pane. Origin should not show up there at all: 
If Origin is showing there simply click on it and then click on the minus (-) symbol under the window. That will remove it.
That’s it. Your game and Origin should never update automatically now. You will be prompted to update when you open Origin and when you launch the game. So remember, if you have Mods –

Hey, I’m new to the sims. What do I do if I haven’t moved my mods before updating? It was auto updated:/ (so, they auto disabled mods). It happened after the latest June 2019 update. Then, I have this issues where I can’t get my Sims into worlds. Do you know how to fix this? I already asked EA and they suggested me to delete all of my CC 😦 I can’t live without CC 😦

I don’t follow general game bugs so I’m afraid have no idea about the Sims not in worlds. You could check the bug forum for that – https://answers.ea.com/t5/Bug-Reports/bd-p/The-Sims-4-Bugs
You need to test your game without any mods – move your Mods folder to the desktop, trash the localthumbcache.package file, repair the game then launch it and see if your game performs properly. Play for a bit but don’t save.

I didn’t know that you had to remove your mods before the update so I updated it with the mods in, my mods are now not working I’ve deleted all my mods the game still says I have them, and when I try to add new ones it doesn’t work… Help.
