My brother bought bioshock infinity from the mac store, and he used his iCloud info in my mac so I could get it to. I feel I'm pretty far into the game, but I bought the steam version during the summer sales. I prefer to have my saved data in the steam cloud to be able to sync to any computer I may install the game onto. Long story short, is there any way to take the progress (saved data) from the bioshock infinite app, and save it to the steam directory where I can pick up from the steam version where I left off in the Mac version? Or do I just have to start all over from the Steam version? Thanks in advance!
