Apple didn't adopt this pervasive OO metaphor, and grouped actions (commands) into groups. Almost all applications need the basics of "open" and "close", etc. so the "File" menu held those. "Cut", "copy", and "paste" were also very common actions, and it was conventional to have an "Edit" menu for that.
