After copying the command line utilities, if the folder you copied into wasn’t there before, it’s probably not in the include path. To edit the include path:

1. Open Terminal
2. sudo nano ~/.bash_profile
3. Add such a line:
   export PATH=/opt/wireshark/bin/:$PATH
   adjust name of the folder according to where you copied the files.

Secondly, I was instructed to put ChmodBPF in StartupItems, but got the following error when I restarted:

“/Library/StartupItems/ChmodBPF” has not been started because it does not have the proper security settings.

I observed that there was something wrong with the ownership of those files. To solve it,

1. Open Terminal
2. Go to /Library/StartupItems/
3. chown -R root:wheel

This will fix the problem.

Then I got the following errors when I ran Wireshark:

The following errors were found while loading the MIBS:
-:0 1 module-not-found failed to locate MIB module `IP-MIB’
-:0 1 module-not-found failed to locate MIB module `IF-MIB’

Apparently there is a problem with include paths. Solution:

1. Click OK on error message.
2. In Wireshark window Edit > Preferences > Name Resolution.
3. Click SMI (MIB and PIB) paths edit button
4. Click New
5. Add the path /usr/share/snmp/mibs/
6. OK and close Wireshark, also close X11.
7. Restart Wireshark
