Forgot your password??? Lost the Install CDs??? have nothing but a computer to fix it??? then this video is for you!
This VIDEO WILL NOT CHANGE ANY OF YOUR SETTINGS/APPS, it just creates a new Admin account.
warning, there have been reports of problems with this technique, although I have done this many of times to Imacs, Ibooks, and macbooks with no problem, u may experience problems, do this at your own risk
And I was the first to upload a video of this technique (june 5, 2008), all others aren't as old or just copies ;)
