Sims 4 Add ons not showing up

okay so I haven't played sims 4 in forever, my pc crashed so I was using a temp and I recently bought a Mac so switching from windows, but EVERY SINGLE expansion pack and kit and all other add ons that I have purchased for sims 4 is saying unowned, I tried repairing it and it did not do anything. Is there some way I can reach out to EA support directly that I have not been seeing or is my purchases just a waste and I will have to buy them all over again? I don't remember what I own but I do know that I bought a lot, I stop playing when Sims got switched over about a year ago. I know I have my expansion packs saved on an external hard drive somewhere I would have to find because I also am in the middle of a move.
