Yes!  I am playing with a MAC.  I didn’t know how to change my password and now I do.

Resetting a user’s password
  1. Log in with an administrator account. 
  2. From the Apple menu choose System Preferences.
  3. From the View menu choose Accounts.
  4. Click the lock button if it appears locked; enter the administrator password.
  5. Select the username whose password you want to change.
  6. Click the Reset Password button or the Change Password button
  7. Enter a new password in both the Password and Verify fields, and add a hint if desired.
  8. Click the Reset Password button or the Change Password button
  9. If a dialog box appears with the message “Your Keychain password will be changed to your new account password,” click OK.
