# MCCC Sims 4: MC Command Center Guide

Source: https://mcccsims4.com/

Last updated: 2026-11-10

MCCC (MC Command Center) is a free script mod by Deaderpool that adds story progression, population control, cheats and hundreds of settings to The Sims 4. The current version is 2026.6.0, tested with the 27 October 2026 patch. Download it from deaderpool-mccc.com, unzip it into Mods\MCCC (one folder deep), enable script mods, then click a computer for the MC Command Center menu.

## Current MCCC version and patch compatibility

| MCCC version | Tested with game patch | PC build | Mac build |
| --- | --- | --- | --- |
| **2026.6.0** (current) | 27 October 2026 | 1.129.39.1030 | 1.129.39.1230 |
| 2026.5.0 | 22 September 2026 | 1.128.90.1030 | 1.128.90.1230 |

Deaderpool lists 2026.6.0 as tested with all expansions and game packs up to Royalty & Legacy and the 27 October 2026 patch. The site says it also works with later patches unless a Tumblr or Patreon post says otherwise, and older game versions are often not supported. A newer MCCC than your game is fine; an older MCCC than your game is the most common reason it fails.

**Where to download (official sources only):**

- [deaderpool-mccc.com downloads](https://deaderpool-mccc.com/downloads.html): `McCmdCenter_AllModules_2026_6_0.zip` (all modules) and, separately, `MCWoohoo_ScriptAndPackage_2026_6_0.zip`. Each has a MediaFire mirror link.
- [CurseForge](https://www.curseforge.com/sims4/mods/mc-command-center): the official listing, but Deaderpool posts there at least a week after the public release so translators can catch up.
- [Deaderpool's Patreon](https://www.patreon.com/mccc_deaderpool): pre-release versions for supporters. The public version is free.

MC Woohoo only works with MC Command Center installed. Some virus scanners flag the MediaFire links or MC Woohoo; Deaderpool says these are false warnings.

## How to install MCCC (PC and Mac)

- Download the all-modules zip from the official downloads page.
- Updating? Delete every old MCCC `.ts4script` and `.package` file first. **Keep** `mc_settings.cfg`, `mc_tuner.cfg` and `mc_dresser.cfg`: they upgrade automatically and keep your settings. Delete them and your settings reset.
- Unzip everything into one folder inside Mods:Windows: `Documents\Electronic Arts\The Sims 4\Mods\MCCC`
- Mac: `~/Documents/Electronic Arts/The Sims 4/Mods/MCCC`

One level deep only. `Mods\MCCC` works; `Mods\Script Mods\MCCC` does not load.
- `mc_cmd_center.ts4script` is always required. Every other module is optional: delete the ones you don't want. All modules must match the version of `mc_cmd_center`.
- Start the game, go to **Game Options > Other**, tick **Enable Custom Content and Mods** and **Script Mods Allowed**, and restart.
- Load a household. A notification shows the MCCC version and every module loaded. That means it is working.

No `.cfg` or `.log` files on a fresh install is normal: MCCC creates them the first time it runs.

**PlayStation and Xbox:** MCCC cannot be used. EA states mods are only available for PC and Mac.

## All MCCC modules and what they do

| Module | What it does |
| --- | --- |
| `mc_cmd_center` | Required core. Links all modules; settings and console commands |
| `mc_career` | Career features |
| `mc_cas` | Body ranges and templates so game-made Sims look the way you set |
| `mc_cheats` | Cheat commands for one Sim or the whole world (Sim and mailbox menus) |
| `mc_cleaner` | Cleanup: homeless ghosts, married name syncing, unwanted outfit categories |
| `mc_clubs` | Story progression for clubs |
| `mc_control` | Limited control of NPCs, letting them run interactions like active Sims |
| `mc_dresser` | Include/exclude lists for outfit items and outfit cleanup |
| `mc_gedcom` | Exports your family tree as a GEDCOM file |
| `mc_occult` | Alien abductions, occult pregnancies, occult population options |
| `mc_population` | Fills homes with homeless Sims, move-in and move-out rules, ancestral households |
| `mc_pregnancy` | Neighborhood Sims marry, have children and age without you |
| `mc_tuner` | Tune autonomous interactions (e.g. Mean, Mischief), block repetitive actions |
| `automation_scan` | Finds and disables autonomous interactions on objects and Sims |
| `mc_woohoo` | Romance settings; separate download, needs MCCC |

Settings-only modules (such as MC Woohoo) appear only on the computer menu. Command-only modules (such as MC Cheats) appear only on Sim and mailbox menus, never on the computer.

## How to open MCCC and use its commands

- **Settings:** click any computer on the lot > **MC Command Center**.
- **Sim commands:** click a Sim > **MC Command Center**.
- **Cheats:** click a Sim or a mailbox > **MC Cheats**.

The shift-click menu is not MCCC. It belongs to EA's testing cheats or another mod. Open the console with `Ctrl`+`Shift`+`C` (Mac: `Cmd`+`Shift`+`C`) on a lot to type these:

| Command | What it does |
| --- | --- |
| `mc_settings` | Opens the settings menu anywhere, no computer needed |
| `mccc First Last` | Opens the MCCC menu for any Sim, even ghosts or Sims not on the lot |
| `mc_cheats` | Opens the MC Cheats dialog without a mailbox |
| `mc_help` | Lists every MCCC console command from the modules you have installed |
| `sim_move First Last` | Move a Sim to the active, another or a new household (works above 8 Sims) |
| `get_pop` | Counts Sims; flags like h, p, a, m, all add detail to the log |
| `rel_set First Last First Last` | Set a relationship between two Sims |
| `kill_sim First Last` | Choose a death type for that Sim |
| `forget_active First Last` | Make a Sim forget the active Sim |
| `flag_sim / flag_clear First Last` | Set or clear flags such as Never Cull |
| `mark_sim / unmark_sim First Last P/M/H` | Mark a Sim for Pregnancy, Marriage or Move-in |

Sims with multi-part surnames need quotes around the last part: `mccc George "Van Winkle"`.

## Things players set up first

- **Story progression:** with MC Pregnancy, random marriage and pregnancy checks run at midnight on set days that depend on lifespan (for example Monday, Wednesday and Friday on Normal). With aging off, the check runs once a week.
- **Households over 8 Sims:** raise Maximum Household Size, then add Sims with `sim_move` or the Maintain Sim command. EA's own Manage Households and CAS stay capped at 8.
- **Keep a family line going:** flag a household as Ancestral in MC Population so the family name stays on the lot.
- **Protect your family tree:** flag Sims with Never Cull before turning on MC Cleaner's Clean Ghosts setting.
- **Careers:** MC Cheats can promote, demote, reset a career branch and change vacation days.
- **Moods:** Change Sim Mood applies the strongest version of a mood for 2 hours. Deaderpool warns that Sims can die of laughter at that level.
- **Confirm it is working:** turn on MCCC > MCCC Settings > Notification / Console / Menu Settings > Notification Settings > Message Logging, then check `mc_cmd_center.log` in your Mods folder.

## MCCC not working? Fixes

| Symptom | Fix |
| --- | --- |
| No MC Command Center option on computers or Sims | Install the MCCC version that matches your game patch; after any EA patch re-tick both mod boxes in Game Options > Other |
| No welcome notification, no log file | Files are more than one folder deep. Move them to `Mods\MCCC` or straight into Mods |
| Modules missing from the Script Mods list | Put the files in the main Mods folder; if that fixes it, delete `resources.cfg` in Mods and the game makes a new one |
| "Last Exception" notification | Almost always an outdated mod or CC, not MCCC. MCCC only reports what the game logs. Read `LastException.txt` in The Sims 4 folder |
| PermissionError [Errno 13] mentioning OneDrive | Stop OneDrive syncing your Sims 4 folder; MCCC must write `mc_settings.cfg` |
| Settings gone after updating | You deleted the .cfg files. Next time delete only the .ts4script and .package files |

**Test with MCCC alone:** move every other mod and CC out of The Sims 4 folder, keep MCCC loose in Mods, and start the game. If it works, the problem is another mod; add the rest back half at a time (the 50/50 method). Deaderpool stresses that mod conflict detectors do not help here: they find two files editing the same resource, not out-of-date mods.

**Known conflicts** listed by Deaderpool: Autosave by sachamagne, Neia's No More Same Sims Everywhere, TwistedMexi's Always Testingcheats, ArtUrlWWW's Pregnancy Mega Mod, the Sticky Clothes mod, kylebeans' Cowplant Tweaks, Candyd's Woohoo is Exercise (with MC Woohoo) and InTeen.

Still stuck? Deaderpool's support Discord (#error_support) asks for a screenshot of your Mods folder, your Script Mods list, `mc_cmd_center.log` and `LastException.txt`.

## Want a living town without managing mods?

Most people install MCCC for story progression: a town where other households date, marry, have kids and move on while you play. [LifeSim](/) is a free life simulator that runs in the browser on a computer or phone, with no download, no packs and nothing to reinstall after a patch.

You can be anyone in any real city on Earth and live day by day. Your character has needs, a job and relationships, and the townspeople are AI-driven, so the people around you act on their own.

## FAQ
