I know that the password doesn't show up on the screen that's all good. I just can't seem to get any further as I am typing my user password but this comes up:
2012-12-04 22:38:14.815 TextEdit[27507:4b0b] NSTrackPersistentURLs: LSSharedFileListInsertItemURL() failed at inserting URL file://localhost/etc/hosts (/etc/hosts)
Why can't I use it? I don't really understand sudo but I do need to change some things around on my mac, can anyone help?
