I had a password on my powerbook. Now I want to have it so that I don't need a password to use my computer (startup, downloads, etc). When I go to the account setup and try to delete the password it says ok but people will beable to get into your computer. I click ok and now it says the password is to short and that I need to put in a correct one, thus is continues to use my old password. How do I delete the password. I also tried to delete the password using the OS install disk but it didn't change the password.
