MY APOLOGIES Terminal not console I'm so sorry. Spotlight search terminal then open and follow the instructions 😉
Oh sorry you drag it to your desktop then drag it into console or open the cd in a finder window and drag it from there.
No just drop it into console like you drop a picture in a file. I am going to add a recording in a second.
How do you drag and drop a jar file that is in a CD?
Sorry, that I action cannot be completed: "or open the cd in a finder window and drag it from there"
