An inability to log out or shut down is almost always the result of an application or process that refuses to quit.

This is indicated by a small spinning gear icon on top of your desktop background or the bright blue screen after all your applications have quit.

You can force your Mac to shut down by holding down the power-on key until the Mac powers off, as indicated by a blank display.
