How to set Sims 3 in Traditional Chinese on a Mac?

Hi,

I gat problem with Sims 3 language setting on my Mac. The supported languages of Sims 3 that I bought on origin include Traditional Chinese. However, I do not get this option when I install the game. And some people said that Sims 3 can set the language by origin. I have bought both sims 3 and 4. For sure, Sims 4 can set the language by origin. However, I do not find the language setting option from the Sim 3 setting option. And I have also tried the way that EA said about how to change the language of Sims 3 online, it dose not work on me .
