How to change language on Sims 3 – Mac?

Could any owner of Mac playing Sims 3 on it tell me if there is way to change language of the game after the game was installed?
Thanks.

If you like registry editing, though I am not sure if it changes the language the Sims speak:

Requires uninstalling but suggester claims it will not delete gameplay progress/folders, etc:
