After searching related questions and answers, I find my issue still unsolved: editing /private/etc/hosts does not work on macOS Sierra.
What in my /private/etc/hosts is the following two rules.
127.0.0.1 localhost
127.0.0.1 www.yahoo.com
These two rules cannot be applied in Safari and Chrome, even after running the command sudo killall -HUP mDNSResponder
. The website yahoo is not redirected to 127.0.0.1.
So what do I miss in the above operation?
And the output of ping -c 3 www.yahoo.com
is as following.
PING fd-fp3.wg1.b.yahoo.com (116.214.12.74): 56 data bytes

If you can ping your /etc/hosts entries as root but not as regular user then try changing permissions on the hosts file to allow everyone to read. This worked for me.
