This process is very easy even for a non technical person with very little knowledge of a computer. To change the administrator password on your Mac OS X you will have to first unlock your system. The Mac OS X install disk will be the key to this process.
The first thing you need is the Mac OS X install disk, if you don’t have it buy a copied version of the same. Once you will put the disk in your CD drive, double click on the Install Mac OS icon on the disk. You will get a Window with large graphic on your screen with a restart button. Tap the restart button and the PowerBook will be restarted and you will reach the install process.
Remember you have not opened this section for installing the OS, but for resetting the password. You will have to only click through windows and until you are finding the usual set of options on your menu bar. Select the Utilities option and click the Reset Password section on it.
Change your administrative password and save it using the Reset Password tool.
After the resetting the password, click on ‘quit’. You will get to know your new administrator password as your computer will restart.
I think this discussion will help you to get out of your problem, but don’t forget the password like your brother, otherwise you will have to repeat the process again.
