Error: Initialization error at start up

[xime12pink]

I'm having the same problem! please help! Yesterday I played without a problem, but today after the actualization the error appeared. I don't know what to do

Ok, for some reason I had 2 Application Support folders and the plist files were there. Changing the languages in the code helped!

Thank you.

Here's a solution that is known to work. It's a little technical though. Don't get scared off from it! You can do it.

1. Go to "/User/<user>/Library/Application Support/Origin/Installer Data/" (where "<user>" is your user name on your Macintosh. The "Library" folder may be hidden by macOS. You can easily reveal it though. See: https://answers.ea.com/t5/Technical-Issues-Mac/135dec40-90f690cf-00000075-495f32a0-Updated-patch-now...
2. Once in "Installer Data" look for files that end in the extension "plist". The file names will be something like: 1011164.plit or 1070252.plist. The exact name will change depending on what edition of The Sims 4 you have along with which Packs you have installed. Open each of these PLIST files. You can use the TextEdit.app in your Applications folder to open these files
3. Look for "<key>Locale</key>" followed by "<string>en_US</string>" (or some other locale)
4. Change the "en_US" (or whatever is listed there) to your preferred language. Refer to the list below. The form and case must match exactly
5. Save the changes to ALL the PLIST files you've changed
6. Make sure the Origin client GUI is also set to the desired language for both the Origin client (Origin -> Preferences or Command+, ) and The Sims 4 (open the Game Properties, then the  Advanced tab)
7. Launch The Sims 4. You may also need to perform a "Repair" of The Sims 4 if you still get the error or if The Sims 4 launches but no text is visible

Let me know if this doesn't work.

This list is the list of supported languages for The Sims 4:

English (US): "en_US"
German: "de_DE"
French (France): "fr_FR"
Russian: "ru_RU"
Polish: "pl_PL"
Swedish: "sv_SE"
Spanish (Spain): "es_ES"
Italian: "it_IT"
Dutch: "nl_NL"
Norwegian: "nb_NO"
Danish: "da_DK"
Finnish: "fi_FI"
Portuguese (Brazil): "pt_BR"
Czech: "cs_CZ"
Traditional Chinese: "zh_TW"
Simplified Chinese: "zh_CN"
Japanese: "ja_JP"
Korean: "ko_KR"

You must choose from this list for this change to work. Anything outside of this list will continue to have the problem.

@MaxisJoe  The only thing .plist I have is ClientInfo.plist and this is what it looks. So... I d'ont know what to do...

[cynthiahmartell]

I play the game in English, even though I have my Origin in Spanish. I already tried changing it to Spanish and it doesn't work.

I was trying to follow the steps to the solution you posted and I have no idea how to fix that, I did everything and I only found a file named "ClientInfo.plist".

After this new update my TS4 switched to English. I had it in Czech before and I cant switch it back. I tried to change language through Origin but even though i picked Czech, it is still in English. Can you help me, please?
