I get errors when I try filters like 'port 443' on Mac OSX. It says invalid filter error. I tried most of these and they almost all failed. asked 19 Jul '13, 17:32  chovy |

So you typed that into the "Capture Filter" box in the dialog that, for Wireshark 1.8 and later, pops up when you double-click on an interface in the "Capture Options" dialog and, in Wireshark prior to 1.8, is in the "Capture Options" dialog itself?
(DON'T type capture filters into the "Filter:" box in the main window. Most capture filters won't work in that box on ANY OS.)
