Hi there

I want to intall Tracktor on my mac, but i don't know my passphrase anymore - stupid, i know!!!!!!!!!!
I have OS X 10.2.6 and my user name, but no passphrase - i tried putting the system disc in, but NO luck!!!
Does anyone know of software that can crack/retrive my password, and where i a can find it??????

Any info will do, PPLLLEEEAASSSEEE
