Wireshark under Mac OS X (& Snow Leopard)

Troubles installing Wireshark under Mac OS X? Try this!

While installing, I got this big error just at the startup of Wireshark:

The following errors were found while loading the MIBS:

The Current Path is: /usr/local/share/mibs/ietf:/usr/local/share/mibs/iana:/usr/local/share/mibs/irtf:/usr/local/share/mibs/site:/usr/local/share/mibs/tubs:/usr/local/share/pibs/ietf:/usr/local/share/pibs/site:/usr/local/share/pibs/tubs

I solved it by giving reading permissions to everyone in /dev/bpf*
This can be done using the Terminal and typing

sudo chmod go+r /dev/bpf*

However this has to be done everytime the computer starts. In order to avoid this you can download this directory and place it in /Library/StartupItems


After doing this the error may be seen again but Wireshark will work properly.
