Ask Max: Reset Username and Password
I have an iMac (OS X 10.4.7).
Repeatedly, they send information about updates to my system and the opportunity to download. However, when I attempt to download, I am asked for my password. I have completely forgotten what it and my user name are. The suggestion is given that I re-use the start-up disk and establish new user name/password. But, lo and behold, when I attempt to do that, I am asked to first give my original password (which is the one I forgot) before I can set up a new one. HELP, Jacob!!
The solution is easier than they make it seem.
With the disc in the drive, restart the iMac and hold down the ™C™ during the start up of the computer. That tells your Mac to boot up off any bootable disc in the CD drive. After you get to the installer, one of the menu items along the top will contain the reset password utility.
