Hi, I am in great need for suggestions. I got a new MacBook 13' yesterday. And in the first-time configuration, I set up an account with a short name which I would like to change minutes later. So following the thread at: http://support.apple.com/kb/HT1428, I set up a new account and switched my home directory. When I logged in using the new account, everything looked fine except iTerm.app and Terminal.app. Both asked me for a password to launch. I gave them my admin password and they refused to take it! So I went to the keychain application, repaired my password in the First Aid. After that, Terminal could launch normally, but iTerm kept on asking for the mysterious password. I re-installed iTerm.app several times and restarted my MacBook several times. No use! One online thread suggested a substitution in the login shell, which I found is not human-readable (well, maybe partly readable). Any idea?
