Mac OS Big Sur : "StepMania" can't be opened because Apple cannot check it for malicious software


I dowloaded the latest version of StepMania (version 5.3.0), for Mac OS (intel) and I have have Mac OS Big Sur (version 11.1).

When I try to open the game, I got this message :

I tried to clic on open anyway but the app closes before it even starts.
I also unlocked the security for all applications but it doesn’t change anything.
I also checked the FAQ first but the terminal code didn’t help for this problem.

Does anybody had the same problem or know how to fix it ?

Did you extract the .dmg to a folder before running the terminal command? It won’t work indeed if you didn’t

I extracted the .dmg to application as asked, then I did the terminal command but it didn’t work…

Ok, I think I understood what I did wrong : I didn’t type the space in the code in the terminal, hence why it wasn’t working… :upside_down_face:

The game is now launching and works perfectly !! :sweat_smile:

I’m sorry for all of this, as I said I’m very clueless when it comes to computer. :bowing_woman:
