andreaxreadss I thought you said you'd bought the packs through the EA App, not through Steam. Any content you own in Steam will only be available in Windows, by design. So there's nothing you can do except repurchase the content. You haven't technically lost it in that it would be available if you ever reinstalled the game in Windows, but it's gone for now at least.
Depending on how much content you own, a cheaper Windows laptop, especially a used one, might be a better purchase than another copy of each pack. Or you could consider buying a subscription to Parallels, which allows you to run a Windows virtual machine on your Mac. It has a free trial if you'd like to test it out before paying. It's also not cheap, especially long-term.
