Hi, I just purchased a used Macbook Pro. I can log onto the main start up screen with my password as an administrator but can not change or delete the passwords for everything. I want to be able to turn on the Macbook Pro and not have to enter any passwords for everything. Is this Possible? Everything is set for a password which I hate. I really do not need any passwords for anything, but this macbook is asking for a password for everything I do. Can someone please tell me how to disable all these password settings. The system is running Leopard Snow X 10.6.
