I've got an iMac I'm selling and I'd rather delete the settings and accounts somehow than sit in front of it for 2 hours swapping CD's to reinstall Tiger. I understand that in Single-User Mode you can delete the Admin account and therefore restore the machine, so that when you turn it on the next time and it doesn't detect any settings it gives you the Tiger intro, albeit annoying. So? Anyone haz the command? Also, post any commands for any other OS' to help OTHER forum guests, I know this would help a lot of people out with their for-sale Macs and new-used Macs.
