You should be able to just start it as tshark -i lo0 and it will wait
for traffic.
[TNS>] Yeah, I thought so to, but even from the 'root' id, I get this:

Running as user "root" and group "root". This could be dangerous.
Capturing on lo0
tshark: The capture session could not be initiated (SIOCGIFHWADDR: No such
device).
Please check to make sure you have sufficient permissions, and that you have
the proper interface or pipe specified.
