After previous discussion on this list (I believe it was this list), I had occasion to use the ChangeShortName app. It worked--for the most part, but I still have the old long name showing as the computer name in the sidebar of the Panther 10.3.4 finder window, and as a heading in the System Profiler window. Is there a way to access and change the computer name in 10.3.4? T, very much, IA.
