Legit Sims 4 with cracked expansions? (MAC)

If I have a legit copy of the game is there anyway i can used the cracked expansion packs with it? 
 sorry if this question's been asked before i've been looking for anything related to this but unable to find an answer.

Hello, and welcome to forum,   
read this post about your question.
Though, buying the base game is almost pointless, since the only advantage you can gain from having such a legit base game is the gallery-access. If you can, just pirate everything - including the base game too.
You can do it but it's complicated, so to avoid further issues, just pirate whole game using this guide.
This pirated game includes:
Pools, Ghosts, Basements, Newcrest neighborhood, etc...
Holiday Celebration Pack
Spa Day
Outdoor Retreat
Luxury Party Stuff Pack
Perfect Patio Stuff Pack
Cool Kitchen Stuff Pack
Spooky Stuff Pack.
