[INFO] Using Mods/CC on a Mac

[ Edited ]

Overview

 

For Sims 4, the process of installing mods and custom content on a Mac is the same as it is on a Windows PC.  Standard mods and cc work equally well (or not at all) in both OSs, and the Sims 4 user folder has the same form and function as well.  There are however a couple of technical aspects to take into consideration which this post aims to address.

 

This guide is only for technical questions about using mods and custom content in macOS.  For help with specific mods or cc, or for in-game issues that may be mod-related, please see @luthienrising's master Mod and CC Issues Support thread pinned to the top of the Mod/CC Issues forum, or create your own thread in this forum.

 

For Curseforge-related questions, please use this thread.

For Documents stored in iCloud Drive

 

In addition to enabling iCloud syncing, some users will have also have iCloud Drive enabled, pushing Documents to cloud storage.  If you have done this and also enabled the "Optimize Storage" option, you may run into problems with mods/cc, saves, etc. disappearing or not loading.  Please see this guide:

And post in that thread if you need further help on the subject.


 

For mods/cc stored in a custom location

 

In order to store mods and custom content on an external drive, or any location other than Documents > Electronic Arts > The Sims 4, you will need to create a symbolic link to tell Sims 4 where to look for the data.  The external drive must be formatted as APFS or Mac OS Extended (Journaled).  This is the definitive guide for storing data externally:

If you need further help setting up the symbolic link, please post in this thread:

 

https://answers.ea.com/t5/Technical-Issues-Mac/-Creating-a-symlink-in-macOS-to-store-the-Sims-4-fold...


 

Common problems associated with storing mods/cc externally

jump to:  "Unable to start," file appears to be corrupted

 

Mods/cc don't show up in-game

 

Double-check that the symbolic link was created correctly and that your files are in the proper location.  You should be able to double-click the symlink you created (the Sims 4 or Electronic Arts folder with the little arrow in the corner) and jump to the folder it points to.  If this doesn't happen, the symlink wasn't created properly, or your computer isn't recognizing the external drive.

 

To see the exact location of a file, right-click it and select Get Info, then look for the file path listed as "Where."  My external drive is titled "Sims stuff."

"Unable to start: Cannot start because the file below appears to be corrupted."

Note that despite my storing my user data on an external drive, the message above still lists the file's location as Documents > Electronic Arts > The Sims 4.  This is normal.

 

When this happens for one or a few files:

 

  • The mod or cc item(s) may be broken, outdated, or otherwise not compatible with Sims 4.  Please remove the file(s) from your Mods folder and test with a different one.
  • The file(s) may be corrupt.  Please download and test a fresh copy.

When this happens with most or all files:

 

  • If the Mods folder is on an external drive, the drive may have an incompatible format, for example exFAT.  Please see this section below.
  • If the Mods folder was transferred from another computer, the files may have been corrupted in transit.  Please see this section below.


 

How to format an external drive for storing mods/cc

 

Formatting a drive will erase it, so start by transferring any existing data you want to preserve to a different location.  Open Applications > Utilities, launch Disk Utility, click View > Show All Devices (green), and you'll see something like this:

The main volume for my drive is exFAT (blue), which is incompatible with Sims 4 mod/cc .package files.  So I need to erase the volume (red), choosing APFS or Mac OS Extended (Journaled) instead.  The alternative, if the drive has enough free space, is to choose Partition, to the left of Erase, and create a new partition with the format of your choice.  You can find more information on partitions and containers in this Apple article.

 

If you see "Erase process has failed," erase the entire drive, titled "USB SanDisk 3.2" in my screenshot above.  Choose "GUID Partition Map" as the Scheme and APFS as the Format.


 

Transferring files between computers

 

Mods and custom content files can be corrupted when transferred between computers, or more specifically to an external drive and then onto a different computer.  This is particularly true when transferring between two different operating systems, e.g. from macOS to Windows.

 

The workaround is to zip the folder that contains the files before transferring it, then unzip it once it's on the new computer.  This protects the files from corruption.  In macOS, right-click a folder and select Compress to zip it, and double-click it to unzip.  In Windows, right-click and select Send to > Compressed (zip) file to zip, and right-click and Extract to extract.


 

Overrides/default replacements

 

With overrides and default replacements, the load order matters: files loading in the wrong order can mean some don't show up in-game at all. Please see this post for a thorough explanation and a way to specify the load order for your cc:

Game won't open unless there are no mods in the "Mods" folder

★★★ Newbie

Hey everyone! I'm hoping to get some help on an issue I'm having. On Friday December 1, my game worked perfectly fine, no issues at all. But yesterday when I tried to play, my game just wouldn't load. I can't get to even the loading screen, my game just spins indefinitely. Sometimes, it will act like it's going to open, but then crash before I ever reach the loading screen. I have searched forums, looked for specific answers, and tried everything. Here are all the things I've tried, but still having the same issue.

 

  • Removing Mods folder and letting a new one populate
  • Removing all Mods from the folder and trying to gradually add some back in
  • Deleting localthumbcache.package
  • Uninstalling and reinstalling Origin (I play on Mac)
  • Uninstalling and resintalling the Sims 4 game
  • Clearing Origin cache and preferences using the RepairOrigin software
  • Restarting and updating my computer
  • Repairing the game in Origin
  • Turned Vertical Sync on and off (don't know why, I just saw somewere that it might help)

Basically, when there are NO mods or CC in the Mods folder, the game loads just fine. But as soon as I add even one single mod to the folder, the game won't open. I've tried several variations of testing my mods, but there is no scenario where my game loads unless I have no mods in the folder at all. In-game, "enable mods and cc" is checked, as is "allow script mods". I have no idea what to do at this point. Here are some hardware specifics in case that makes a difference

248GB storage 8GB memory

Apple M1 chip

macOS Sonoma 14.1.2

 

TIA for any assistance!

Start with a whole new clean Sims 4 folder by following these instructions - https://answers.ea.com/t5/Technical-Issues-Mac/READ-FIRST-Sims-4-Mac-Help-Guides-and-Troubleshooting...

 

Once you've launched the game and the new folder has been created, enable CC in the in-game options then quit. Now add one piece of CC into the Mods folder. I would try something from Peacemaker as I know and trust his CC https://simsationaldesigns.blogspot.com/ then load the game.

 

Does it show up in the game and work?

Thanks for responding! I just tried that, and when I added in one Peacemaker mod, the game loaded. However, once I added a few more (also from Peacemaker), it wouldn't open again.

(Mac) Sims4 application won't respond.

Before the game was working fine with all the mods but now on adding a few expansion packs the game isn't responding anymore. Without the custom mods such as skin, clothes etc the game is starting up just fine with just the script mods. I tried all troubleshooting methods and even tried adding in mods slowly and the game eventually does start up. But when I try to add all the mods back at the same time, the game goes back to not responding again. So, I tried to copy the mods, allowing them to slowly upload in iCloud and for once the game started up so exited the game but few hours later it reverted back to the application not responding again. How I figure out which mods exactly is/are creating problems when if I slowly add in the mods, the game works but if added together it doesn't work?

@haleyym8 ugh, I am having this EXACT same problem. As soon as I add mods the game stops responding. Even script mods are working and the game opens but custom mods when added together makes the game stop responding.
I even tried to add mods slowly and that worked but hours later when I opened up the game again, it stopped responding.

Re: Game won't open unless there are no mods in the "Mods" folder

@haleyym8

What is your game setup? Are you using an external drive? Have you copied the CC files from another location on the machine or another one? Using iCloud or created a symlink?
