Re: The Sims 3 64-bit for Mac: New Disc Codes
@NeonGreenCow You couldn't install the game via disc. But you could certainly register the disc codes in Origin, and they would work just like packs you bought directly from Origin (unless the codes have been used already).
It's possible that registering the discs would only give you the 32-bit version of the respective packs, but in that case, you could contact EA customer support and ask that the "entitlements," as they're called, be added for the 64-bit version as well.
