Hi Scotty,
I am working off our apple macbook and have been requested to update the computer.  However, I must have misplaced what I thought was the correct password.

While I do save most wireless passwords of my clients in my own computer, the password you are referring to is the system’s admin password. If you do not remember your password and are the only admin on the computer then the best way to reset the password of your mac is to boot from the install Disk (Leopard if you have it or the one that came with the comuputer) by holding down the C key. Then choose password reset utility under the utilities menu in the menu bar.

After you’ve reset you’re password there, you’ll be able to restart your computer and be back up and running again. Hope that helps.
