Instead of controlling the window from the top right hand corner of the screen, Macs controls are on the top left hand corner of the screen. The red circle closes the window, the yellow minus minimizes the window, and the green plus changes the window to its optimal size. There is no maximize button like on Windows. The optimize button opens the window to the ideal size for itself, not maximizes it to fill the screen.
