The easiest thing to do would be to register your codes in Origin or the Sims 3 store, which would allow you to download all of your content from Origin for free. If you still have your CD cases, those codes will be on the backs of the inserts; they're the same ones you used when you installed the game via disc. If you don't have those inserts, you can look for the codes on your old computer, or perhaps they were transferred to your new one with your other data:

If none of this works, then your only other shot would be contacting EA customer support and providing photos of your discs, cases, inserts, etc. But that takes more effort and isn't guaranteed to work.

Once you've registered your codes, it's a good idea to do a clean uninstall of any files that were transferred to your new computer. If you don't remove them, those remnants could prevent you from launching the game going forward.

When you're ready to install, there are several steps you'll need to get TS3 running on your new mac. Bluebellflora has written a very helpful guide to installing TS3 on a mac, with descriptions of the various errors you'll need to handle:

I know this is a lot; feel free to ask for help with any of it. Just describe which step isn't working or what you don't understand. It would also help to know the specs of your mac, as well as which packs you plan to install. Of course, you may decide to throw up your hands and Bootcamp your mac instead (as a few of us have), and we can help with that too.
