Installing 10.6 Snow Leopard Resets your /etc/hosts file
OS X Daily reader Todd Harris has tipped us off that when installing Mac OS X 10.6 Snow Leopard, your /etc/hosts file is reset. If you followed a tip we posted a while back about how to block access to specific websites then this is particularly relevant to you, so be sure to manually adjust /etc/hosts again so that the sites you want blocked are reincluded. Of course there are many other uses for /etc/hosts too, so the long story shortened is this: if you have a custom /etc/hosts file, back it up prior to and restore it after you have finished installing 10.6 Snow Leopard! Thanks for the tip Todd!
