I need to reset my administrator password. My Adobe Flash Player requires updating but when I try it asks me for a password. I have been told it is my Mac's administrator password that it is requiring. My Mac was set up for me by someone who is now dead and I had no idea that they had set a password. I therefore need to reset the password. I am A VERY BASIC USER and my fear is that any complicated resetting or rebooting, etc will not work and the whole Mac will be rendered useless. Can anyone please help with a simple answer on how to either reset the password that is fool proof or to tell me if I need to take it to a store for a reset please? I have a MacBook Pro (Software is Mac OS X Lion 10.7.5) Thanks people.
