Forgetting your User Account Password can be frustrating. Thankfully, there's a rather simple fix for forgotten passwords. Insert your OS X CD, restart your computer and hold down the C key so that the computer starts up from the CD. Once the OS X Installer appears, choose Reset Password from the Installer menu. This opens the Reset Password application. Click the icon representing your hard drive, and then select your account from the pop-up menu. (Do not choose System Administrator or Sendmail User.) Enter a new password for your user account and click Save. Quit Reset Password, and then quit the Installer. Now restart your computer. You can once again make administrative changes to your Macintosh. Now jot down your password and store it somewhere safe to avoid this problem in the future!
