Hello
Hi and welcome to the forum.
(1) Where would our saved game have been stored on the PC?
(2) Even if we find it, would the same save game file work on the mac?
(3) And if it WOULD work, where should we put it to enable the game to find it?
Your saved game(s) are in a file called "machinarium.sol". It's a cross-platform file so your PC .sol will work on your MAC.
Have a look-see in the "
Shared Machinarium .sol Files" forum for instructions on how to find/swap this file (you'll find the info you need in the Win FAQ).
Good luck. Don't hesitate to write back if you run into any troubles.
