Guter Ansatz, die Host Database sieht tatsächlich anders aus:

# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
#74.208.10.249 gs.apple.com
#127.0.0.1 gs.apple.com
