How do I download The Sims onto my Macbook Retina?!

Hi!!

I haven't played The Sims in awhile and during the period of time I was not playing I had switched from a PC to a MacBook Pro Retina, as you know you cannot insert disks into the Retina and I've already got the previous disks. Which seems pretty useless. 

if anyone knows how I can download my disks onto here that would be AMAZING!!

Thanks 🙂
