Forge Server won’t work *Mac

[Robohead]

I am on a Mac and trying to make a forge server for 1.12.2. I follow the normal steps and load it up as usual but this time when I open up the forge file to start the server, I get an error: The Java JAR file “forge-1.12.2-14.23.5.2854.jar” could not be launched. Check the console for possible error messages. 

 

FYI, I checked console and there is nothing there. 
 

Does anyone know how to fix this problem? Thank you in advance.
