Changing the language of the Sims 3 on MAC

Hi everyone! I m currently playing Sims 3 on my Mac in a english version. 

I am from Hong Kong and I can read both Chinese and English but it will be more difficult to read the words in English version and take longer times to understand the meaning.

I've been playing sims 3 in Traditional Chinese version in the past (as I play it on a PC), however, when I re-downloaded and installed sims 3 base game and expansions on my macbook air, I found that I cannot convert the language from English into Chinese version. 

I tried the method that told me to rewrite the "system.reg" and "update_always.reg" into the desired languages but I can only rewrite it in the "update_always.reg", not the "system.reg" as it did not have any "locale" there.

Then I tried to rewrite the .plist file, but there was also no "locale" there and cannot change the language code.

Can anyone try to help me by telling me the method of changing language?     I really need HELP!    Thanks!

Hello,

There are no other ways that I know to change the game language, there is only thing to do, which is reinstalling again..

How I can reinstall the Sims on spanish?

Hello,

After uninstalling the game completely, all you need to do is reinstall the game and choose the language Spanish when the launcher starts.
