Sometimes there are spikes in this issue being reported and it usually coincides with a game update or macOS update. Game updates can render CC/Mods incompatible so you need to check with the creator that the content you use has been updated to work with the current patch level of the game. When macOS updates are applied this can sometimes change iCloud Drive settings so check the location of your Documents folder in System Preferences:
- Are CC and Mods enabled in your game options? If not enable them and restart the game.
- Is your game fully patched up to date?
- Are the CC and Mods you’re trying to use fully compatible with the latest version of the game? Check on the creator’s website that they are. The good creators will always check their content is compatible after an update and release an updated version if necessary or possible. Check the SimsVIP broken Mods page for updated lists after each patch.
- Are the CC/Mods definitely for Sims 4 and not Sims 1, 2 or 3?
- Have you unzipped the downloaded CC/Mods so you are only placing .package and/or .ts4script files in your Mods folder?
- Do you have iCloud Drive enabled to store your Documents folder in the cloud? Check in System Preferences. If so disable it so your Sims 4 data is stored locally on your Mac.
- Have you tried repairing your game? Right click on the game in your Origin games library and select repair game.
ItsaprilXD’s fabulous guide to installing CC/Mods on a Mac is also worth a read.
Here’s a link to using the Sims 4 Tray Importer in macOS. Getting it to run seems a bit hit or miss but it appears that with a little perseverance some users are getting it to run in Sierra.
Sims 4 Tray Importer for Mac
The guide is really detailed and very easy to follow and the comments are very informative too – good luck!
Update January 2018
As of January 2018 the Mac version of Tray Importer is no longer compatible with the Sims 4:
S4TI for MAC is no longer available. The app no longer works with the latest update of the Sims 4 and the developer does not want to provide support on MAC (platform it does not have and which greatly complicates its development …)
Sorry folks, seems like it’s the end of the road for us Mac users. I’ll update this page if it is resurrected.
Update April 2018
Well, seems like it’s up and running again as of the 4th April 2018. Just follow the links above!
Lots of Simmers, Mac and Windows users, still have issues installing CC and Mods into their game because of the compression methods some creators use. I was late to the CC party and experienced this as the built in Archive Utility in macOS can’t handle 7z files.
The best tool I have found to extract 7z and rar files is The Unarchiver and you can download it straight from the Mac App Store here. It’s really simple to use as it sets itself up as the default unarchiver on your Mac so once installed you don’t have to do anything. I don’t normally like any software that overrides Apple’s Apps but I’ve been using this ever since my CC obsession started and had no problem with it.
- Download The Unarchiver from the App Store. It will automatically install.
- Download some CC in 7z or rar format. The downloaded file will now look like one of these in your Downloads folder:
- Now just double click on the 7z or RAR file (like you would a normal Zip file) and The Unarchiver will extract the contents into a new folder in your Downloads folder. You can now move the .Package files from the extracted folder into your Mods folder.

- It’s always a good idea to get rid of the special characters (*%-_ etc.) from CC filenames as it will help to speed up your game a little. For a further explanation see my page here. Rather than manually change every filename I created an Automator App which will get rid of the characters for you. You simply drag the files to the App and the special characters are removed.
