When I set up my first Mac, a PB, I named it "Mustafa's computer", which is how it's recognised by syncing devices. Now I have a Mac mini, which I set up by copying over all the files and settings, etc. by FireWire. Now, of course, that's also called "Mustafa's computer". How can I change the name by which each machine is known -- I can't see it in System Preferences.
