Problems Redeeming My Sims 3 Expansions on EA Account

Hello everyone,

I’m having a really frustrating issue with my Sims 3 expansions and I hope someone here might have advice or has experienced the same problem. I have the 64-bit version of The Sims 3 on my EA account, but I’ve run into a lot of trouble with the expansions. The only add-on I was successfully able to add and that actually works is Late Night. University Life and Pets are also on my EA account, but they only work for Windows – even though I’m using a Mac. The other expansion packs — Seasons, Tropical Paradise, Supernatural, and Ambitions — I cannot redeem at all. Whenever I try, it says the codes have already been redeemed, even though I never activated them on any EA account myself.

I own the physical CDs for all of these expansions from back when I was a child. I installed and played the games on my desktop computer back then, long before I ever had an EA or Origin account. I would really love it if there were a way to add these expansions to my EA account so I could enjoy the full Sims 3 experience on my Mac. I can even provide photos of the physical CDs as proof of ownership if needed. It’s really disappointing that these legally purchased expansions are basically unusable for me now, and I’m hoping there might be some solution. 

Thank you for any help or advice!
