Hi all - the original problem is no one remembers the password to log into our MacBook. At startup it goes to the user login screen and prompts for a password. I have the Mac OSX disc, tried putting it in the optical drive and pressing C, that didn't work. I have tried many times to do Command + S and Command + V. The only thing that does work is if I press Option at startup it goes to a login screen with no username - just asks for a password and shows a picture of a large padlock. And once again, no one knows the password... I know if I could get it to boot to the disc drive I could reset the password. But no luck there.
I'm very confused as to what to do because of course the laptop warranty has expired.
I appreciate any help you can offer.
Thank you.
