packs not working

okay so I downloaded sims4 through steam on a Samsung windows computer and bought the "get together" pack and got the holiday celebrations which is free. I just got a MacBook and transferred everything over to the Mac but the only problem is both of the packs keep saying "available on windows". I don't have steam on the MacBook since I knew steam doesn't support Mac and Im pretty sure I've done everything you can do lol. I've uninstalled and re-installed sims4, I've checked my ea to make sure I'm logged in correctly, I've repaired the game, I've logged out of EA and I even talked to EA customer support for an hour. is there anything I can do or am I gonna have to start an entire new game?
