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.
