We all know you can change the host name in OS X through /etc/hostconfig, but that can have problems, such as Apache not working right.
In the Terminal type:
% sudo open -a /Applications/TextEdit.app /usr/share/init/tcsh/rcIn TextEdit look for a line:
set host = `hostname`change `hostname` to anything you like:
set host = "Big Papa"There you go, new host name without the hassle of hostconfig.
