How to Install MCCC in Sims 4

Install MCCC step by step

1. Download McCmdCenter_AllModules_2026_6_0.zip from the official downloads page. Details on the download page.
2. Unzip it. The game does not read zip files. On Windows, right-click and choose Extract All. On a Mac, double-click the zip.
3. Open your Mods folder.
   • Windows: Documents\Electronic Arts\The Sims 4\Mods
   • Mac: ~/Documents/Electronic Arts/The Sims 4/Mods
   If there is no Mods folder, EA says you can create one.
4. Make a folder named MCCC inside Mods and move all the unzipped .ts4script and .package files into it. Keep them together in that one folder.
5. Start The Sims 4. Open Game Options > Other and tick Enable Custom Content and Mods and Script Mods Allowed. Apply the change and restart the game.
6. Load a household. A welcome notification lists the MCCC version and the modules that loaded. Click a computer or a Sim: the MC Command Center menu should be there.

The folder depth rule

The game looks for script mods only one level inside Mods. This is the mistake behind most failed installs.

Watch for a doubled folder. Some unzip tools create MCCC\McCmdCenter_AllModules_2026_6_0\, which puts the files two levels deep. When MCCC is too deep the game shows no error and writes no log: the mod is simply missing.

The module picker on the main page lists the exact files to keep.

Which files you need

• mc_cmd_center.ts4script is always required. It is the core that every other module plugs into.
• Every other mc_*.ts4script is optional. Delete the ones you do not want. Keep the .package files next to the scripts.
• All modules must be the same version as mc_cmd_center. Never mix files from two releases.
• MC Woohoo is a separate zip. If you want it, unzip it into the same MCCC folder.

On a first install there are no .cfg or .log files. That is normal: MCCC creates them the first time it runs in the game.

Check that it works

• Script Mods list: Game Options > Other > Custom Content should show the MCCC modules under Script Mods. That proves the game found the files.
• Welcome notification: shows on loading a household, with the version and modules.
• Menus: a computer and any Sim both show MC Command Center.
• Log: turn on Message Logging under MCCC Settings > Notification / Console / Menu Settings > Notification Settings. Then mc_cmd_center.log in the MCCC folder begins with "Initializing MC Command Center version".

Mac, OneDrive and console notes

• Mac: the steps are the same and the zip is the same. Only the path changes. In Finder use Go > Go to Folder and paste the Mac path above.
• OneDrive: if your Documents folder syncs to OneDrive, MCCC can fail to save settings with a "Permission denied" error. Deaderpool's fix is to stop OneDrive syncing the Mods folder.
• After every game update: the game switches mods off. Re-tick both options, and install the MCCC version for the new patch. See updating MCCC.
• PlayStation and Xbox: not possible. EA says mods are only available for PC and Mac players.
