I have a MBP that is running Lion 10.7.5. When I start up the laptop I enter in my password. That works. When I try to enable automatic login for myself it asks for a password. When I enter in the same password I use on startup it states the password is wrong. The same thing happens when I try to change my password. It says my old password is incorrect. How can I get the system to recognize my old password? Thank you for looking.
