I have unearthed an old working iBook G4 which I'd like to clean and then give away. I don't have a copy of 10.4 on hand to install. And I'm not terribly interested in wiping the installed applications off of it, more so I just want to make sure there's no application user data left on it.
At this point all I can think of is to just create a new user, and delete all trace of the existing user from /Users/. I personally have very little experience of 10.4 however, and only got involved in Mac since 10.6, so I'm concerned about things I might be missing.
