Forum:Sims3 won't work on macbook

Hi I know a lot of people probably don't play sims3 anymore since sims4 came out but i still really love the game. I have recently got wifi and a macbook and in doing so i tried to download my sims3 games onto it and created my sims3 account... well i successfully downloaded some of the games i attempted at downloading even got a bunch of free stuff off the sims3 page.. and i can't stress this enough i am terrible with computers soo heres my big question... every time i try to play sims3 on my macbook it will load to the main menu and come up with a notification saying my disk has stopped or my disk is an invalid copy and i was wondering what is happening and if theres anyways for me to pay sims3 on the macbook or just leave it on my PC..? I've read a bit online and a lot of people have had trouble with sims3 on MacBooks but i haven't found anything yet similar to what I'm experiencing.. thanks!
