“cannot execute binary file” I did this
Dragged MCNSAModPack.jar -> desktop
Dragged the .jar into the terminal window then typed “java -jar MCNSAModPack.jar”
Keep it in the modpack directory, not on the desktop.
Type “cd ” then drag the modpack folder into terminal. Press enter.
After you do that, then type “java -jar MCNSAModPack.jar”. Press enter.
Worked! thanks! 🙂
