- Moved to Library/Application Support/com.Owlcat-Games.Warhammer-40000-Rogue-Trader/UnityModManager
I think that is correct. It's working for me on Linux via WINE.
I did see something online where someone was unable to interact with the game on Mac and they said they needed to goto the folder where the game was installed and run the game by:
Right click on App -> Get Info -> Open Using Rosetta
Another thing mentioned was to press FN + CTRL + F10 to open the mod manager in game.
