katewest420 Yes, there's a tutorial here on reddit: https://www.reddit.com/r/Sims3/comments/kvs80x/comment/gj1g8fr/
But the apps you need to do the conversion only work on PC, so you will need either a working PC or else something like Parallels which can run Windows virtually on a mac.
There IS a workaround to do it natively on mac--- lepid llama's unpacker ---- but 1. you do have to manually do each pack and. 2. it doesn't really work for lots and 3. most importantly, while it did technically work for me it somehow managed to make such lag that it's untenable to play 😭
