Normally if a Macbook is locked up with an administrators password, usually one cant easily get in but can resort to reformatting the hard drive as long as they are using Snow Leopard and that will knock out the old passwords, allowing you to take over.
I had a macbook that was set up in such a way I could not reboot into a reformat state, I could not erase the drive and reformat....I could not do anything at all and spend 3 hours trying everything i could think of, to no avail.
Until this.
Follow this exactly and be aware of the spaces between a few letters for without putting in those spaces, this will not work but if dont properly and its easy to do, you will take control of the passwords, become the admin and delete any earlier admins on the Mac.
There is a space in the first line between the k and the -y
There is a space in the second line, between the t and the -uaw.
Those are the only two spaces needed.
Please, come on now, all you need is nothing: OK, restart your computer, hold down Command-S and type in the following:
/sbin/fsck -y [Enter]
/sbin/mount -uaw [Enter]
rm /var/db/.applesetupdone [Enter]
reboot [Enter]
Once you've done that the computer reboots and ask you to set up an admin password. From there you just change all other account passwords in the account preferences!!
So who said you needed a CD?
