How do I find the save files on a mac?
Viewing post in Save Files
I'm not sure exactly but here are some info from Unity's documentation:
In recent Unity releases user data is written into ~/Library/Application Support/GrizzlyGamerStudio/Robin Morningwood Adventure. Older versions of Unity wrote into the ~/Library/Caches folder, or ~/Library/Application Support/unity.GrizzlyGamerStudio.Robin Morningwood Adventure.
Hope it can help :)
