I inherited an iMac from my brother-in-law who removed his old password and has forgotten the temporary one he installed. How can we unlock the computer?
iMac, Mac OS X (10.3.x), likely upgraded
Resetting or changing a password:

If it's running Mac OS X 10.6.8 or earlier, insert a Mac OS X install DVD, restart with the Option key held down, click on it, and use the Reset Password utility.
If it's running Mac OS X 10.7 or newer, restart with the Command and R keys held down, open the Terminal, and use the resetpassword command:

If it the Keychain password that needs resetting:

If the computer has a firmware password set, contact Apple.
