It is not possible to recover a password from the hash. Take the computer to an Apple dealer to have the password removed.

Wrong, It's Possible. Last 16 digits and letters is Md5 hashes containing his password, the other 16 (first one) containing info about his machine. Basically you can brute force it or rainbows tables the last 16 digits and numbers , on the good computer it shouldn't take that long...

The character string provided by ⇧⌃⌘⌥S at the firmware password dialog is 33 printable characters long. An md5 hash is 16 bytes long (32 hexadecimal digits) and can contain any non-printable character. So, how do you figure the last 16 digit character sequence refers to an MD5 hash containing the password?
