Sims 4 packs aren't loading in game

Overview

This problem appears to be mainly, if not entirely, related to the Sims 4 packs in question being installed to a different location than the base game.  The EA App sees the packs as installed, because they are, but the game can't find them to load their content.  In order for the packs to load, the "The Sims 4 Packs" folder must be in the same location as the Sims 4.app:

Solution

If you're running into this issue, the first step is to identify the affected packs and find their codes, as listed here:

https://sims4.crinrict.com/eng/extras-2/available-packs-dlc/

For example, Get to Work is EP01; For Rent is EP15.

If you've installed Sims 4 onto an external drive, make sure it's plugged in and recognized.  Open Terminal, which is inside Applications > Utilities, copy and paste the following search command, and enter:

find / -name "EP01" 2>/dev/null

Except instead of EP01 , you'll use the code for one of your missing packs.  Don't change anything else about the command.  Terminal may take a few minutes to complete the process, so please be patient; you'll know the search is finished when the command prompt reappears.  If Sims 4 is installed anywhere on your computer, you will see at least one result.

You can ignore the entries that start with System/Volumes, as these are redundant.  For the rest, you may see something like this:

/Users/username/Applications/The Sims 4 Packs/__Installer/DLC/EP01
/Users/username/Applications/The Sims 4 Packs/EP01
/Users/username/Applications/The Sims 4.app/Contents/Delta/EP01

The first part of the file path must be the same for all three entries, as above.  If The Sims 4.app is in a different location, like this:

/Users/username/Applications/The Sims 4 Packs/__Installer/DLC/EP01
/Users/username/Applications/The Sims 4 Packs/EP01
/Applications/EA Games/The Sims 4.app/Contents/Delta/EP01

That's the problem.  You'll need to move the "The Sims 4 Packs" folder to the same location as the Sims 4.app.  In the above example, that would mean moving the Packs folder out of Users > your username > Applications and into Applications > EA Games.

If this doesn't work, delete the Packs folder, run the EA App Recovery tool (under the Help menu at the top of the screen, with the EA App in focus), and restart your computer, then redownload the missing packs.

If this doesn't help either, please reply to this thread, and post the results of the Terminal search for at least two of your missing packs.  Feel free to remove or black out your username where you see it, if you want, but leave everything else intact.

You can copy and paste the results from the Terminal window, or you can use cmd-shift-4 to take a screenshot of the relevant portion of the screen.
