Make sims 4 expansion packs able to go from xbox to other platforms

Ive spent so much money on expansion packs on my xbox, but want to move it all to Mac because of better opportunities for more fun gameplay and and easier way to play overall. But since I can't rebuy the packs, I can't switch. I just want my game to go to my Mac, for the love of everything just PLEASE make me able to switch over my expansion packs. Soon enough for me its either going to be to rebuy all the expansions on the Mac (which there is no way I will ever do that because that completely wasteful), or just quit playing overall because of how frustrating it is trying to play on xbox. I love the sims, and really don't want to quit playing, but it's seriously frustrating how this has been set up. So please, just let me be able to have all my expansion packs that I paid for on my Mac sims 4.
