Savegame transfer from Iphone to Mac

Hi Guys,

I'm trying really hard to tranfer my savegame to my mac.
This Game is really awesome but i'm getting headaches from the "small" Display.
I downloaded the "IPhone Version" on my Mac from AppStore.

Please give me some advises for a possibly savegame tranfer.

I have no Problem with buying the Steam-Version for Mac if it's needed.

Very very Kindly and grateful asking
Timological
