Re: Redeemed Sims 3 codes but wont download as says only available on windows?

I play the Sims 3 on my Mac and I never got around to registering all of my packs.  Recently I started playing again but missed having the packs I used to have so I bought Pets, Supernatural, Movie Stuff, Showtime and Diesel Stuff.  After registering them I went to the EA app to install them.  But when I got there is said they were Windows Only.  In the past there was no such thing as a Windows only expansion pack and when I look at the packs on the site they say that they're compatible with my Mac.  I play the Sims 3 and my current packs with no issue.  Can someone tell me what's going on?  Do I have to buy them again and make sure they are Mac version?  How do you tell if they are or aren't?  So confused.
