Hello, I need to edit hosts file on my MAC but unable to save it. Text Editor says 'Couldn't save' I seems to have an Admin rights on the machine: if I open System Preferences-> System-> Accounts it says Admin next to my login, and If I do Edit User- there is a checkmark at 'Allow user to administer this computer' If I open 'get info' on the file it is not locked, I am the owner, and I have 'read ad write' access . Do I need a special editor? (I just doubleclicked on the file) Would you have any other ideas? Thanks a Lot!

The hosts file is in the hidden /etc folder so it is ruled by the superuser "root". You have two choices: Enable the root user so you can login with super powers; or use Terminal. Editing in Terminal is really quite easy. Launch Terminal. Type sudo pico /etc/hosts and hit return. You will be asked for your password. You won't see any characters on the screen when you type the password. Just hit return when it is typed and you should find yourself in a text editor called Pico. Now use the up-down-left-right arrows to get yourself into position to type the line. You can use the tab between entries on the each line. When you are finished typing, hit the ctrl-x keys. It will ask if you want to save changes. Type a "y" to indicate yes. Now you have a hosts file with your new entry.

Thanks a lot! Pico worked perfectly.
