I think this is it. idk if the file will show up.
@putridpicklemilk Try doing a clean uninstall of Origin; the reset tool does miss one file:

Restart your computer before trying to install Sims 3 again.
If that doesn't help, please make sure Origin has full disk access. Click the Apple icon in the upper left corner of your screen, select System Preferences, then Security & Privacy, then the Privacy section, and scroll down to Full Disk Access. (It has a folder icon.) Add Origin to the list if it's not already there. Then run the Origin reset tool, restart your computer, and try to install.
If that doesn't help either, do another clean uninstall of Origin, create a new user account on your Mac, and try installing into that account. Make it an admin account; the username should contain only letters and numbers, no special characters, accents, etc.
