@Elowi The entitlements, as they're called, are still lagging behind for packs. You might need to give the process a few more days.
Please open a Finder window, click Go at the top of your screen, hold down the optn (alt) key, and choose Library. From there, open Application Support > Origin, and create a folder called Installer Data (exactly that, no variation). Then open your Origin library and repair the game: right-click on the Sims 3 icon and select repair.
This should create a file in the Installer Data folder that will both make the base game icon in the launcher light up and allow you to download content. If neither happens, please make sure the file is in fact in Installer Data. If it's not, run the Origin reset tool, open Origin once to create the Origin folder, and then try the above process again.
The pack icons being grayed out will probably (hopefully) be fixed with an update soon, but in the interim, it doesn't appear that there's any negative impact on gameplay.
You were right, I had to create the folder but after I did and repaired (for the umpteenth time) it the plumbob did light up and I was able to download things! Fingers crossed it keeps working and thanks so much for the help!
