Update 02/10/19 – EA announced today that they will be releasing a 64-bit version of Sims 3 in early 2020!
We knew it was coming and now it’s real:
32-bit apps are dead in 10.15. If you’re thinking about upgrading when the public beta is released in July, or when it is released in the Autumn, you may want to install Mojave or an earlier version of macOS on an external drive beforehand if you want to continue to play the legacy sims games.

Lol. To be fair 32-bit is so old now although it would be nice if EA/Aspyr updated the games. Shouldn’t think it will happen though.

Yeah, I agree. That’s the annoying thing. I wish aspyr would at least update Sims 2. I don’t expect EA to update Sims 3 but

And SimCity, though I don’t know if it’s only for the App Store version or if our copies we purchased on Origin are going to be fixed too.
