Hello. Could someone please explain how i set this sudo password? Im trying to run an app that asks me... "myHack requires root permissions via sudo to perform the installation. Please enter your password." So i enter my login password and get... "Invalid password." ... "sudo: can't open /private/etc/sudoers: Permission denied sudo: no valid sudoers sources found, quitting" Whats going on here and how do i fix it? I have already gone into System prefs/Users and groups/login options/network account server/open directory utility/edit/enable root user. This doesn't seem to have worked though. Thats even if it's related? Any help is much appreciated! Thanks, Chris.
