Transferring packs from Steam to EA

So my pc died a few days ago and I decided to upgrade to M4 MacBook Pro. But when I went to download sims and reinstall everything, the packs I bought on steam say “Available on Windows” and won’t allow me to install them. Does anyone know if EA can transfer these for me? Or how to get in contact with EA directly? I already tried asking Steam for refunds on the ones I bought in the last week but they denied all requests. Any help or ideas would be appreciated!
