I'm trying to activate the root user account on my G4 Dual 1Ghz/OS X 10.2.2 by following instructions available at Apple site and OS X Missing Manual. I try to activate root with NetInfo by doing... 1. Security>Autheticate, type in my admin password 2. Security>Enable Root User. I type the new passwords. Then I get the error message "NetInfo Error : NetInfo write failed (operation succeeded)" Then "NetInfo error: Can't authenticate new user and password" Then "NetInfo Error : NetInfo write failed (operation suceceeded)" again and "NetInfo error: Can't authenticate new user and password" once more. Then "Alert: You must re-authenticate to make additional changes" I've also experienced file permission problems while installing a copy of Adobe GoLive. At the end of the installation process, it says I don't have enough permission to install. I find this weird since I'm on an administrator account. Do I have a OS-wide permission problem here, I guess. As far as I remember I've never done anything other than creating a new account when I bought this machine. Never messed with permissions. I'd appreciate it if somebody can tell any solutions to this root user problem. I know basic stuff about command line terminal. So if there is a command line way to activate root, that would nice too. Thanks!
