So, I tried searching for the .toa-data folders/files in my ToA game folder, but I've found nothing. The "profile.json" files is also nowhere to be found (the game plays perfectly fine btw). Can anyone tell me why that is ? 

I just want to transfer my save files to a newer version.

Heya - because the .toa-data folder starts with a period/full-stop, it's by default hidden on mac. Hitting shift + cmd + period should show hidden folders.
