you can hold down the power button for several seconds to force your MacBook Pro to shut down. If you choose to do this, when you start it up again, you should boot into Safe mode to ensure that any disk problem which the forced shutdown might have caused will be fixed. (If you reach the login screen in Safe mode, then its disk check was able to take care of such a problem.) After logging in, you can restart to boot into normal mode again.
