Thank you.Adding a little onto what odin said, you can currently move saves between either device, though you can only play older files on newer versions, not vice versa
Since you are coming from an iphone you could transfer and play your files on a macbook so long as you bought the game there and don't mind not being able to play those specific files on your iphone until it updates
No problem, if you have any further questions or run into issues do feel free to askThank you.
