How to make changes to Mac /etc/hosts permanent?
I have a Mac Air that my little brother uses. Unfortunately, he likes to waste his time on computer games :(
To prevent him from doing that, I added a line akin to the following to my /etc/hosts/ file:
127.0.0.1 somereallyaddictinggamesite.com
However, my /etc/hosts file always refreshes every time I reboot my Mac, so this line goes away every time I turn on my Mac.
How do I make permanent changes to my /etc/hosts file?
