Hello,
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… 
The game is now launching and works perfectly !! 
I’m sorry for all of this, as I said I’m very clueless when it comes to computer. 
Hi all,
I’m having the same issue as the OP. I have Big Sur version 11.4
I looked at the FAQ and I’m not understanding the steps while accessing the Terminal.
" To do this, open Terminal and run the following command: xattr -dr com.apple.quarantine /path/to/StepMania, replacing /path/to/StepMania with the path to the directory containing the StepMania executable (manually typing it out, or dragging the folder containing the game executable directly onto the window to fill it automatically)."
Can someone explain to me in simple terms? I have it downloaded and I have the folder installed in the Applications folder. I tried dragging the folder to the Terminal and it didn’t work.
You have to open a terminal window, and then type xattr -dr com.apple.quarantine, which will tell the game to allow access.
Here’s a video version of the whole process.
(If its not visible, here’s a direct version of the video).
Thank you, that was helpful!
On a related note (future release).
