What is the backbone of the Apple OS?
                                                
                                                
                                                
                                                
                                            
                                                                                I am just wondering what is the backbone programming language that the Apple OS is made of.
I am fascinated on how their OS look. I know that creating and Operating System is done by using, I think, C languages?
Is their any other language that Apple uses for their OS?
