I’m not sure if this is a Mac specific issue so I’m just throwing it out there.

If you are trying to download University Life for the Sims 3 but can’t because Origin is telling you  it hasn’t yet been released, please post in this thread over at EA’s Answers HQ. It seems to be an issue with the latest update – 9.10.2.4863 – 398079.

It doesn’t seem to be operating system related. but the more info EA get the better so they can (hopefully) fix it.
