I have the same problem, but some of my content I can download in the launcher. The weird thing is, that I can see everything I bought over the years when trying to download in game. And when looking at the sims 3 store it is also shown under where I have bought the things over the years. For instance it would let me download Riverwiev but not Monte Vista, Hidden Springs and BarnacleBay, there are all shown under things I have bought (theese are redeemed with codes), but they are not shown on my front-page profile (the sims 3) as owned. The same with a lot of the Expansionspacs (are not shown on the front-page profile in the sims 3 store), but they are shown in EA-App.
I figured out that the objects in the purchase history I can click on, and go to the objects page, and it says download right away, also can be downloaded through the sims (in game).
But some of the things are not properly registered in the sims store, so when trying to download things, you have bought, but when you go to the objects page, it doesn't say owned, cannot be downloaded (in game). That is even though that you can see them in game and can click on download, but it is saying download fail every time.
So I actually do not think it is only a MacBook problem, but also specially a sims 3 store problem. And many have bought the things 10-15 years ago, and the old things probably and registered, because of the sims 3 store- glitch.
Does anyone know how to get your stuff properly registered?
