When we upgraded all our Macs to macOS Sierra, my daughter was upset because Sims 3 broke. After much scouring of the internet, I found the solution and tweeted about it:

My daughter's fave game, Sims 3, was getting stuck on the loading screen in Sierra. This Info.plist edit fixed it: https://t.co/HzjgWnB7cr

It dawned on me, though, that if that forum post ever vanishes, I'll be in trouble with future new Macs and/or reinstalls, so I thought I'd document it here, too. Read no further unless you (or a family member) play Sims 3 and want to get it working in macOS Sierra. And really, try the linked forum post first; this is just a backup plan.

The following is quoted verbatim as posted by user 'Ashpeef' on the Sims forums. I organized it as a numbered list and formatted some text, but left the content unchanged.

Go to Installed Content and uninstall everything you don't want anymore; Close the Launcher; Remove the dcdb0.dbc file from the DCCache and store it in a safe place. Move the dcdb1.dbc in the DCCache and rename it to dcdb0.dbc. Start the launcher and proceed with step 5 and 6 again. Rename dcdb0.dbc back to dcdb1.dbc and store it also at that. I have The Sims 3, Showtime, Ambitions, Master Suit and Seasons on there and I've been playing it but i got Late Night and Pets and installed it, but now suddenly it wont open and i can't play it, people suggest uninstalling them and re-installing them but i can't work out how to uninstall them, I've tried dragging the icons into the Trash but it wont let me. Please help, the icons are in.

It's probably the Launcher that crashes at the time it hands over control to the game itself. You could try starting the game directly, bypassing the Launcher. Here's how (also a rather long story, I'm afraid...) :lol:

1. Within your Applications folder, locate and open the folder The Sims 3
2. Find the application The Sims 3.app, then right click (or hold the Control key and click if you can't right click) to get the context menu.
3. In that menu, select Show Package Contents. A new window opens with only one item: the folder Contents
4. Within that folder there is a file info.plist (usually the second item)
5. Right or Control click that file for the context menu and there select Open With
6. You'll probably have to scroll down almost to the bottom of the list to find TextEdit.app. Use that program to open the file.
7. Now the real thing: locate the line <key>CedegaGameName</key> about 2/3rds down. Note: not the one just above it with CedegaGameDir!
8. The next line should end ...Bin/S3Launcher.exe</string>
9. Change S3Launcher.exe to TS3W.exe and save the file.

The next time you start the game, it should begin straight away with the EA and Maxis logos.

If you later on want to start with the Launcher again, just do the same thing, this time changing TS3W.exe back into S3Launcher.exe

To make this easier to do in the future, I made an alias of the info.plist file in our Documents folder. And as I'm not a masochist, I used BBEdit, not TextEdit, to edit the file.

It is inevitable with the Sims 3 that for every patch series update or CC installation we do, something would get messed up and the only fix is a fresh, clean slate. To achieve that, or only option is a reinstall. And with Sims games, a manual uninstall is always necessary as the game uninstaller(s) usually leave bits of information behind.

This is important, especially if you have CC placed in the ModsPackages folder - the framework components need to be removed, to ensure everything is wiped out properly for the next reinstall to work without any glitches.

If any of the registry entries or leftover folders listed below are missing after you uninstalled the game, either via Start Menu or Control Panel, that is perfectly fine. This guide is to verify that these things are gone before we do a clean reinstall.

Before You Begin - Do a Backup!

Backup User Folders

• If you'd like to backup your user files (saved game data), the steps from Sims 2 can still be applied, just using a different folder structure. You might also want to backup the ModsPackages folder contents located in the respective paths
• If you're uninstalling and you have custom content or mods that you would like to save for another installation, you can find them in these default locations for your Operating System.

Patch 1.12 onwards

• Windows XP:My DocumentsElectronic ArtsThe Sims 3ModsPackages
• Windows Vista/7 & Mac:DocumentsElectronic ArtsThe Sims 3ModsPackages

Patch 1.11 and below

• In the legacy framework install path:
  • Windows (32-bit): C:Program FilesElectronic ArtsThe Sims 3ModsPackages
  • Windows (64-bit): C:Program Files (x86)Electronic ArtsThe Sims 3ModsPackages
  • Mac OS: Contents > Resources > transgaming > c_drive > Program Files > Electronic Arts > The Sims 3 > Mods > Packages
• If you have any Expansion Packs and maintain custom content in a ModsPackages folder other than in The Sims 3 root, remember to backup the contents in those paths, too.

Backup Digital Downloads

• Paths in Origin's Settings
  Go to the path shown in the image to find your Digital downloads, and backup those installer files. You might also be interested to read Game Help:EADM Issues.

Manually Uninstalling in Windows OS

Uninstall

Go to Start/Control Panel/Programs & Features (Vista/W7) or Start/Control Panel/Add Remove Programs (XP)Then follow the on-screen instructions to uninstall the game - it's a standard 'next, next, next' type uninstall. There will be separate uninstall options for every expansion and the base game, just like with The Sims 2.

Uninstall according to release dates, going backwards.

If you have EADM and/or CAW, you can include these to wipe everything EA related from the machine but it is optional. Unless you have a known issue with the EADM version installed, or the Launcher is not working correctly, or EA has released a new EADM version, etc, you won't need to uninstall EADM.For the most part CAW can be left alone.

Restart

Now you need to restart your computer, before continuing with the guide.

Cleaning up Leftover Folders

It is best to check for these, if after a restart, the folders and registry entries are still not cleared properly.It's fine if the entries are missing, as the uninstaller may have done its job properly. But double-check to make sure you're not just looking at the wrong spots.

Delete the game files (in the default location):

• Click the Start button and select My Computer.
• Select the Local Disk (C:) drive folder. (If you installed to default paths)
• Select the Program Files folder.
• If you want to remove Base game:
  • Select and expand the Electronic Arts folder
  • Right-click The Sims 3 and select Delete.
• If you want to remove Expansion/Stuff Packs:
  • Right-click the EP/SP name eg: The Sims 3 World Adventures and select Delete.
• If you want to remove the tools:
  • Right-click The Sims 3 Create a World Tool and select Delete.
  • Right-click The Sims 3 Create a Pattern Tool and select Delete.

• Go to My Documents
  • Select and expand the Electronic Arts folder
  • Right-click The Sims 3 and select Delete. (You should have made a backup in step 1.)
  • Right-click The Sims 3 Create A World Tool and/or The Sims 3 Create a Pattern Tool and select Delete. (Optional. You should have made a backup in step 1.)

Additional notes (OS-specific):

Windows 7 / Vista

If your user group do not have Administrator access, UAC will make a copy of the ModsPackages folder in VirtualStore. For a complete cleanup, these folders need to be checked, too. If you cannot see the folder or its contents, read this section on how to Unhide files & Show file extensions.

• Go to VirtualStore
  • Go to this path and ensure that it is empty as well.
  • If you have an Expansion Pack or Stuff Pack, you may want to verify the content for those respective folders in the Virtual Store are removed as well.

OR

Cleaning up the Registry

Beginner - Use 3rd-party Registry Utility

• Download this registry cleaner program, and install it, following the on-screen instructions.
• Launch the program after installation has completed.
• Click the Registry tab, and click the Scan for Issues button.
• When scanning has completed, click the Fix Selected Issues... button.
• When you're prompted to backup, click Yes, accept the default name and location
• Click Fix All Selected Issues

Advanced - Edit Registry manually

Backup the registry:

• Hold down the Windows key and press R.
• At the Run command, type in 'regedit' (minus the quotes) and select OK.
• Click on File and then Export...
• Choose a location and name for the file; this will be your backup registry file.
• Click Save.

How To Uninstall A Sims 3 Game On Mac Os

Delete the registry keys:
(If you haven't installed any Expansion/Stuff Packs, those entries will be missing)

1. Locate the following entries by expanding the ' to get to the next level or the ' to collapse it.
2. If any of the entries are missing, that is fine. This means the uninstaller for that program has done its job.
3. If you're uninstalling certain packs/programs only, do not delete the 'parent' folder but remove its 'children'.
4. Right-click each of the entries below and select Delete.
5. If you're uninstalling the tools as well, select the entries for these as necessary.

• HKEY_LOCAL_MACHINE
  • SOFTWARE
    • Classes
      • .Sims3
      • .Sims3Pack
      • Sims3

Manually Uninstalling in Mac OS

To completely uninstall the game [source: this post], carry out the following steps.On Lion and Mountain Lion, some of the folders are Hidden, so you may need to unhide them first before you can view them to delete.

• Uninstall the app as normal, start with the latest SP/EP (if applicable) and work your way down to the base game
• delete your /Applications/The Sims 3 folder and any others for SP/EP (if applicable)
• delete your /Users/<User>/Library/Preferences/The Sims 3 Preferences folder
• delete your /Users/<User>/Library/Caches/<any Sims 3 related folder or file>
• rename your /Users/<User>/Documents/Electronic Arts/The Sims 3 folder – you can keep this as a backup, so that you can put your old savegames, syles, screenshots etc back once reinstallation was successful.

If after doing the above, you still cannot reinstall/patch, try these additional instructions [source:thesims3.com forum thread]:

• Navigate to the Disk Utility which can be found in Applications -> Utilities -> Disk Utility
• Run the Disk Utility and select your hard drive in the left hand column and press 'Repair Disk Permissions'

There's now a CCleaner for Mac, which can help with the Uninstall cleanup steps.

After the Uninstall

After you have uninstalled and done all that, reinstall and patch by following these steps. Complete Patching instructions can be found here.
