Applicable only to the 32-bit version of the Sims 3. For the 64-bit version uninstall through Origin
These instructions are to completely delete everything Sims related from your Mac – CC/Mods/Saves/Downloads, everything (to manually uninstall a single EP/SP please read this guide). If you’re having problems with your game this is a last resort but it will only work if you really get rid of everything. Even then it’s not 100% guaranteed that your game will work again after reinstalling but it should give it the best chance possible. A lot of Preference files are left behind when you uninstall The Sims 3 using the Uninstaller in the Applications folder. In order to make sure you have a completely clean uninstall of the game, follow the steps below.
Please note that the Preferences folder has really important files in it so make sure you don’t delete ANYTHING apart from the files mentioned below. You can render Applications useless and potentially screw up the OS by deleting the wrong things. This is why Apple have hidden it from Lion onwards.
– If your Uninstaller isn’t working or has mysteriously disappeared you can still follow these steps but you must firstly trash your TS3 Applications and user data. To do this go to Finder > Applications and drag The Sims 3 folder to the trash. Remember to trash any shortcuts you have in your Dock and/or on your Desktop too. Next, go to Finder > Documents and trash the Electronic Arts folder. If you have other EA games in there DON’T trash this folder, instead open it and just trash The Sims 3 folder.
– If you have the Uninstaller use it to uninstall all your EPs, SPs and the Base Game. When you have deleted all of these you need to do the following:
For Leopard/Snow Leopard users:
– Open a Finder window, click on your Home/User folder (the one with the picture of the house next to it), open the Library folder in the right-hand pane then open the Preferences folder.
For Lion and subsequent versions of macOS:
– Make sure you are in Finder by clicking anywhere on the Desktop, it will say Finder in the menu bar, next to the Apple logo.
– Click on Go. When the dropdown box appears press the Option key (alt) on your keyboard. The Library folder will now appear. Click on Library then open the Preference folder.
In the Preferences folder delete a folder called Cider Preferences, if it is still there, and The Sims 3 Preferences folder, if it is also still there. Now you need to delete any files that have Transgaming and Sims in the name. They will start with com.transgaming…… in the file name and look something like this:
Next, open the Caches folder in the Library folder and delete all folders that start with com.transgaming. In the Cookies folder (same Library folder) look for a file beginning with com.transgaming… and delete it (thanks to CPUGenuis at AHQ for finding that one!).
Note for those running Lion and subsequent versions of macOS – In the main Library folder there is a folder titled Saved Application State. In there you may also see a whole load of folders that look like this:
As you can see they have transgaming in the title. You need to delete these too. Thank you to kaosgirl and Snapdragon over on the official forums for bringing this to my attention. Now you should empty your Trash. Restarting your Mac wouldn’t hurt either.
Once you’ve done all that you can start reinstalling the game again, patching after the Base game and each subsequent EP and SP if prompted. It is always advisable to patch using the super patch. Just to be on the safe side I always reinstall in the order the EPs and SPs were released:
- The Sims 3
- World Adventures (EP01)
- High End Loft (SP01)
- Ambitions (EP02)
- Fast Lane (SP02)
- Late Night (EP03)
- Outdoor Living (SP03)
- Generations (EP04)
- Town Life (SP04)
- Pets (EP05)
- Master Suite (SP05)
- Showtime (EP06)
- Sweet Treats (SP06)
- Diesel (SP07)
- Supernatural (EP07)
- Seasons (EP08)
- 70’s, 80’s & 90’s (SP08)
- University Life (EP09)
- Island Paradise (EP10)
- Movie Stuff (SP09)
- Into the Future (EP11)
If you want to cleanly uninstall an Expansion/Stuff Pack follow this guide.
Thank you for taking the time to share your experience and knowledge, Bluebellflora. Hugely useful and supportive. I can’t say I’m looking forward to uninstalling and reinstalling TS3, but at least I know I shall be doing a thorough de-cluttering job! All the best, Lita. 🙂

Hi BluebellFlora,
I am playing on a fairly new Mac and I just uploaded Island Paradise. I try to update my game often and when I got the notification to update it before playing today, I did. My game downloaded a new patch and the 1.55 version update. However, after it finished verifying and applying the update, the launcher gives me the message, “Some files have been modified, please reinstall.” I do not want to reinstall my entire game. I tried simply uninstalling and reinstalling Island Paradise and I continued to get the same message after downloading the update.
Do you know of a way around this problem? I’d like to keep my game updated.

Drag everything Sims 3 related to the bin from your Applications folder, the Electronic Arts folder in your Documents folder and then all the files in the Library.

Seems like you have a been a huge help to other so far, so fingers crossed you’ll be able to solve my issue! I used to have TS3, installed originally from a CD. It was un-installed years ago and the CD was misplaced. Yesterday I purchased the starter pack off of the Origin site and had no issues installing it on another computer in the house (PC) now trying to install it to my computer (MAC). The origin application that was installed yesterday is not showing an install/download option beside the base TS3’s game only seeing a “play” option (but the three expansion packs are) Of course I know I need the base to download the expansions. When I click on the “play” option just to see what happens I receive an error “service initialization failed (0x0175dcbb)”. At this point I have manually uninstalled every TS3 item on the computer manually as I cannot even find the game in the system anymore, also uninstalled origin app and still not seeing an option to install the base TS3 game.(as the origin support page suggested). I tried out of curiosity to install a patch for the base game incase i was missing the file but no luck. Any suggestions? My OS is Maverick.

But I had to delete the electronic arts folder and all my sims games I deleted the castaway game as well. The files in the library and the installer in the applications folder. I found I had to access it through finder as if I went straight into applications it didn’t show up. The then restarted my mac and then I was able to install the new disk. Hope that helps.

This is my first Mac computer, so I literally have no idea what I’m doing!
I just thought I’d leave you a note to let you know that if people follow these steps and have purchased their games through Origin, each one of them will need to be re-downloaded prior to being re-installed. I am probably a bit silly for not realising that sooner but I have always purchased games on disc up until now.
Not sure if it will work yet, waiting for the base game to download so I can patch it, but I’m hopeful, and it was much more helpful than the EA staff…So thank you! 🙂

Restart your Mac and try again.

by doing this, will it delete my saved households and files on the sims? also, how long does this uninstalling/reinstalling process take
LikeLike
Yes, unless you keep your Sims 3 folder in Documents > Electronic Arts. The amount of time it takes depends on how fast your CPU is, what kind of internal storage you have, the speed of your disc drive/download speed, there is no fixed amount of time.

Hey, thanks for you help! I did everything you said and was able to finally delete it fully. Unfortunately I deleted the electronic arts folder and deleted my trash bin as well. now its gone! I was too quick here.. what can i do now? When I try to reinstall it, it gets stuck at the file 3 from 8xx. Hope you can help me!!!

Have you checked your internet connection, how fast is it? If it’s a bit slow then it may well time out.

It’s impossible for the game to slow your Mac down when it’s not running. Perhaps your hard drive doesn’t have much space left? Or you have too many things running at once?

Dear BluebellFlora,

I tried going through the steps you have above. On my EL Capitan there’s no cider preferences folder. Sims 3 preferences, yes. But there aren’t any files titled com.transgaming. I even did a search just in case. None.

If you’re happy that there are no such files then the uninstaller may have got rid of them already.

Yeah I’m happy but I’m unclear on whether it’s a good thing that I cannot find the files or a bad thing – for a clean uninstall?

Hi,
Thanks for the good advice and its just lately that I’ve had this problem; When I install Late Night and Ambitions, they cause an “unknown error” to pop up and the game won’t load. When I go to the sims folder in the applications drive, those games are not listed but they do show up in the “uninstall” list in the folder. When I uninstall both games the game loads and plays fine. I’ve contacted EA, they offer the same advice you do with the exception of the order in which to install the games (they say reverse order); it has not made a difference. I’ve deleted every tansgame and sims file in preferences, cache, cookies, emptied trash, restarted but LN and AMB will just not show up and cause the “unknown error” I’m tired of waiting hours every few days for EA techs to tell me the same thing with no resolutions. Thanks

In addition to all those com.transgaming files in my Preferences folder, I also happened to find a folder labeled “The Sims 3 Preferences” that wasn’t mentioned in this article. In THAT folder there aren’t any com.transgaming files, but various exec files and .reg files, as well as one labeled “wineserver-[name of my device]”. I don’t know if I should delete it since it wasn’t mentioned in this guide and you warned of the dangers of deleting other files in the Preferences folder. Thoughts?

When I use the uninstaller for TS3 it asks me to pick a game to uninstall but nothing comes up in the selection box. I’m so frustrated bc I was getting the “Game Disc Not Found” error when the disc was inserted and I’m going through this whole process of trying to get this damn game to work. I used to play it a couple years ago but then got TS4 and uninstalled it for some reason and now I’ve attempted to get the game again but its been giving me problems ever since. >:0

Hi! So it’s July 2018, I’m super late, and I’m sure a lot has changed since 2013! I was following your instructions, and was wondering, should I delete com.transgaming.thesims3… files I found elsewhere? Found some hidden in Library> Application Support> com.apple.sharedfilelist> com.apple.LSSharedFileList.ApplicationRecentDocuments
All I did was search com.transgaming in the Library folder and that came up. I’m guessing it’s a minor thing though. I have a feeling this will be enough, especially because as I was looking it was clear my game installed totally wrong (no launcher whatsoever, no Electronic Arts folder, and the uninstaller didnt even find a game to uninstall. womp. Major fail EA, lol. Though probably my fault for uninstalling incorrectly)
Also wanted to add, for users not as computer savvy, there maybe com.transgaming files that belong to OTHER origin games so make sure you look for something sims-related in the name! com.transgaming.nancydrew… was one of the ones I noticed on my computer 🙂
Thanks for your stuff bluebellflora you are a deity!!

Hey thanks for the prompt reply! Your clean uninstall made my game work!!! yay! (that is until I also installed all the expansions. ugh! back we go. I also don’t see the supposed “bootstrap.exe” anywhere. only cider.)
I’m not sure of the names of those ones, or even why they were there! I already deleted them 😦 After the successful reinstall of my base game, (and the subsequent failed reinstall of my expansions) those files are NOT there!!! So that is just totally bizarre. I’m on a Mac Air High Sierra, doubt that changes anything though.
Weird… wish I knew…

So I stupidly downloaded the 32-bit version of The Sims 3 for my Mac, without realising I was a few hours early for the official release of the 64-bit & Metal version. It “finalised” the installation (doesn’t run of course) and I think I’ve removed it but just wanted to make sure that there wasn’t anywhere else, deep within the OS, where it might be hiding, so I don’t loose any space on my Mac because of it?

Hi, I gotta start by thanking you for all your posts, you have made my life as a Mac sims 3 player muuuuch easier!
I am only now coming to grasps with the switch from 32 to 64 bit but i’m having some issues. I started by just installing the new 64 bit version, unaware that I should delete the old one first. I then had to uninstall the old version manually using your guide. Now the game plays, but for some reason, Island Paradise, on which I have all of my games and houses saved, isn’t installed, so I can’t access anything. I’m scared to do anything that might delete everything i’ve spent hours creating 😦
Any idea what I should do/try, without risking losing my progress?
Thanks in advance xx
