Villodre: AUTO-ANSWER: ON They're in
/Users/<username>/Library/Application Support/Boxer/Gamebox States/com.gog.dungeon-keeper/Current.boxerstate/C.harddisk/SAVE/ I searched, using find -name, for a file which could be in an "snapshot" saved at every profile who runs the game, like in Windows. The file was "SETTINGS.DAT" and every savegame follows the SAVE000, SAVE001, et cetera pattern.
Thank you SO MUCH for this. I had just started that scenario where everything is open, you get a lot of dragons and your first Scavenger's Room, then I got raided by the other keeper and everything went FUBAR. I decided to quit and load instead of waiting for the enemy to destroy my Dungeon Heart (DK should really have a "restart scenario" button) but it seemed I did not have a specific save for it. When I loaded (what I though was) my last save, it was in the middle of the previous scenario, then I screwed up even more by overwriting the other file by accident.
I decided to pull my previous Continue file from Time Machine, and couldn't find the Save folder by any means.
Thank you again!
