Older Game: New Mac Computer
I have a Sims 3 deluxe addition, DVD-ROM software, that I bought years ago, but never used. I recently got a new mac, but seems like I am unable to install the program on my new computer? On the DVD-...
@k_ker21 I've moved your post to the Mac section.
The disc issue isn't new: all versions of macOS starting with El Capitan (10.11) will fail to authenticate Sims 3 discs. But El Capitan is newer than the game, so that wouldn't have made it into the official requirements printed on your disc case.
The more immediate problem though is that Sims 3 doesn't run in Catalina (10.15) at all. The game is a 32-bit app, and Catalina is 64-bit only. There's no way around this issue, at least for now. EA has announced a 64-bit-compatible version of the game, to be released (hopefully) this year, but it's not clear at all when this is going to happen.
In the interim, your only options are to play on a different computer, to install Windows alongside macOS (via Bootcampe or Parallels), or to install Mojave on an external drive or USB and boot into that when you want to play. For the second option, you'd need enough enternal storage to dedicate to Windows: 100 GB is probably the bare minimum, plus enough left over for the Mac side. For the third option, you'd need temporary access to a Mac running Mojave or earlier. Let me know if you want more information about any of these options.
Edit: Yes @igazor, I'm moving a bit slow today. I take 16 hours off from posting, and suddenly my fingers barely work anymore.
