Widnows to iMac save game conversion

Hi all

I have a Southend game on my Windows laptop but have recently purchased an iMac.

However, my problem is that I'm unable convert my windows save file which is a .FM to IOS. Does anyone have any suggestions for this and is it even possible? I've currently tried the 'cross-game/save' feature and just simply transferring via a memory stick (iMac didn't even recognise the .FM file to even let me see it).

It would be very much appreciated if anyone has the answer!

Thanks
Ryn

Have you tried Steam Cloud save? I don't know if this will work but worth trying.
