Oh, another update to integrate the previous email. Inside the source code of mDNSResponder ( https://opensource.apple.com/tarballs/mDNSResponder/mDNSResponder-878.260.1.tar.gz) I found in "mDNSPosix/Makefile" this: " # Check the nsswitch.conf file. # If 'mdns' does not already appear on the "hosts:" line, then add it right before 'dns' cp -f /etc/nsswitch.conf /etc/nsswitch.conf.pre-mdns sed -e '/mdns/!s/^\(hosts:.*\)dns\(.*\)/\1mdns dns\2/' /etc/nsswitch.conf.pre-mdns > /etc/nsswitch.conf " Probably, It's better to use this "sed -e '/mdns/!s/^\(hosts:.*\)dns\(.*\)/\1mdns dns\2/' /etc/nsswitch.conf.pre-mdns > /etc/nsswitch.conf" instead of the existing one. What do you think?
