steam error

[Advance-san]

when I start the game with https://github.com/m5kro/RPG-Maker-MacOS-Launcher it says Error: Steam has not been detected

May be related to a big using the tool itself that may do an additional check, as it was described in the readme the steam check was removed. Like for example your tool excepting steam in all cases.

I don't know if rpg maker have mac support but you should try to run this instead and open the project with it
