@nadsyons (and all the people who clicked Me Too) If your Mac runs Catalina, this is the issue: Sims 3 is a 32-bit app, and Catalina is 64-bit only. There's no way around this. But EA has announced a 64-bit-compatible version of TS3 for macOS, to be released some time this year. Here's the full announcement:
In the interim, your only options are to play on another computer, to install Windows on your Mac (via Parallels or Bootcamp), or to install Mojave or earlier on an external drive and play from there. If you'd like help with any of these options, feel free to ask.
If you'd rather not try those or wait for the new version of TS3, you can request a refund from EA:
