how to open a locked apple computer

I HAVE ASKED YOU ON HOW TO OPEN A LOCKED APPLE COMPUTER TWO MONTHS A GO. BUT THERE WAS NO RESPONSE FOR THIS QUESTION. I DECIDED TO ASK YOU AGAIN TODAY BECAUSE MY COMPUTER IS STILL LOCKED. YOU ALWAYS SEND ME THE TITTLE “HOW TO OPEN LOCKED APPLE COMPUTER” WITHOUT SHOWING ME THE WAYS TO OPEN IT.MY QUESTION IS: IF YOU DON’T KNOW THE WAYS, WHY YOU SEND ME THIS TITTLE,BUT IF YOU KNOW, WHY NOT YOU TELL ME THE WAYS.
