1) I am used to with the Microsoft Window and (a little bit of) Linux Operating system
2) I am not familiar with the Macintosh OS
3) I saw some MacBook (The OS is Mac OS X 10.6.8) at a company (production environment)
4) If I want to backup the original setting of the DNS (at Linux Ubuntu), I will do this command:
sudo cp /etc/resolv.conf /etc/resolv.conf_backup
5) My question: How to do it on MacBook? The same?
