Wireshark on Mac OS X is downright ugly. It requires XQuartz, an X11 port for OS X. Wireshark have announced that they have begun a steady migration to Qt. The move has its critics, and backers. I back whatever looks better than it currently does. As Miguel de Icaza of Xamarin points out, it is possible to look good on Mac OS X with the Gtk+ port for Cocoa. So what gives?
