Increase Wireshark Font Size on Mac OS X
Wireshark has a preference setting for the font of the capture display but it won't let you change the main font used for other UI elements such as like menu, toolbar and dialog windows. The default for the main font is illegibly small on my Mac OS X Leopard system -- I used Macports to install Wireshark and its dependencies. To fix it you need to add the
gtk-font-name setting to your
.gtkrc-2.0 preference file:
echo 'gtk-font-name = "Sans 14"' >> ~/.gtkrc-2.0
This will affect all applications using the GTK 2.0 toolkit but I guess that's ok.
