macOS Drawing Sphere in Cocoa OpenGL

Wonder how to draw a sphere which I can center anywhere in the window and not just centered at the origin..

Thanks in advance

You can apply a translation transformation to move the sphere away from the origin, or change the view matrix (IOW, move the camera off-center so it's not looking directly at a sphere at the origin). Not sure if you're asking something different because you did mention "Cocoa OpenGL" specifically, but for most things it's the same as any OpenGL.
