the error keeps popping up for sims 3 install after downloading on MAC laptop. an alert appears saying to turn off firewall and restart the computer (this did not work) and if that doesn't work run origin in administrative mode but does not tell me how to do that.
@Tashia016 Does your Mac run Catalina? If so, that's the issue: Sims 3 is a 32-bit app, and Catalina is 64-bit only. (The error message is kind of misleading.) There's no way around this problem. However, EA has announced a 64-bit-compatible version of Sims 3 for macOS, to be released (hopefully) some time this year.
In the interim, your only options are to play in a different computer, to install Windows on your Mac (via Bootcamp or Parallels), or to install an earlier version of macOS on an external drive and boot into that when you want to play. If you'd like more information on the last two options, let me know.
If you only just bought Sims 3 and don't want to wait for the new version, you can request a refund instead:
