OS X :: Reset Mac Password Without Install Disk

I was speaking with a friend and he asked me about resetting his mac without the install disk and I told him well you can despite what other people tell you the only major downside is that you'll lose all keychain passwords, but if you've really forgotten your password, it's better than nothing. So I decided I would write a post telling you the simple way to reset your password without the install disk. Trust me this does work! It may take you a few times until you get it right. [URL]
