Re: Sims 3 stuck on 'finalizing'
@BridgetSimmer Being on a Mac has everything to do with this. The unknown error is Mac-specific and has several causes, depending on your specs and which packs you have installed. So please list those packs, and whether you've uninstalled any of them while troubleshooting, as well as your specs, and I'll write out the workarounds you need to apply. Here's how to find your specs:
In the meantime, you can run the Origin reset tool for Macs to try to get rid of the "finalizing" message. It doesn't always work, but then again you don't need to run the game through Origin anyway.
