Hi, my friend got a mac running osx but realized that since he has no access to the admin account, he can't install anything or do very much really (the parental controls are fierce!). I'm trying to help him get the admin password he deserves, but I can't find a way. The previous owner lost the install CD and for some reason he cant use single user mode. If there are any password cracking programs for mac, an in depth tutorial being linked will be helpful.

Thanks in advance!
