brassebrannstrom Yes, you can register your codes in the EA App, IF they haven't already been used. Install the App, open your library, click the Redeem Code button in the upper-right corner, and add each code in turn. They're the same ones you'd use if you were installing the game via disc.
When you're done, the base game and all expansions and stuff packs should be available to download through your library. You'll only see the base game entry, but when you click Download, you'll be asked which EPs and SPs you'd like to install at the same time. The game should run fine, minus some extra bugs specific to the 64-bit Mac version.
It's possible, however, that only the Windows entitlements for the base game and your packs will be added to your account. In that case, you'll need to contact EA customer support and ask that the 64-bit entitlements get manually added. Use this link:

The "missing content" category should work; use the live chat option rather than email. You can then explain the issue and ask for the entitlements. Feel free to link this master thread covering the subject if the support rep needs further context:
