Problem solved. The Accessibility Preferences - Enable Mouse Key was the problem. I do not understand what good it is doing. If you tick that - the result is disconnection of the keyboard. I restarted the computer and was told to press the Option Key 5 times. then Abra Kadabra - LO and BEHOLD: it worked ! A Miracle ! A MIRACLE !
