sims 3 game launcher not working mac os tahoe 26.1

Hello, ive seen alot of discussion on the launcher having a system failure when downloading .sims3pack cc. so i deleted all of them. But, I have tried downloading packages as normal and it still hasn'[t worked! I have redone the framework for a new mods folder and yata yata, but still nothing. Deleted everything from the cache, and deleted my sims 3 folder and started over. Is there any solution? i have scrolled through reddit for hours but nothing has worked.

  • 1drumbeat​  Are you talking about files with the .package extension, which go in Mods > Packages; or are you talking about files with the .Sims3Pack extension, which go in Downloads and need to be installed through the launcher?  Any .package files you see will load as long as they work and you delete the cache files after adding them, but they don't show up in the launcher.

    If it's hard to describe what you're doing, you can always post screenshots.

    Thanks so much! i didn't realize package files dont show up in the launcher lol. i got one of my .package files from freshprince creations to work but no other cc. My sims 3 pack files just crash the game so i stopped trying to upload those. I

  • 1drumbeat​  Do you want help getting the .package-based cc to work?  If so, the first thing to do (if you haven't already) is to delete the five cache files in Documents > Electronic Arts > The Sims 3.  These should be deleted any time you add or remove mods or custom content.

    • CASPartCache.package
    • compositorCache.package
    • scriptCache.package
    • simCompositorCache.package
    • socialCache.package


    If that doesn't help, double-check that you're looking in the correct location for the custom content items.  For example, some players have missed the fact that a cc item is only for young adults and adults, not teens, or vice versa.  And make sure the files have been extracted to .package form.  The game won't read them if they're still in .zip form.

    If that's not the issue either, feel free to link a few items, and I'll test them myself.
