In particular, these commands:

sudo ifconfig lo multicast
sudo route add -net 224.0.0.0 netmask 240.0.0.0 dev lo

fail since lo does not exist.

Changing lo to lo0 made further progress but route does not appear to have a netmask specifier. The following was accepted:

sudo route -nv add -net 224.0.0.0 -interface lo0

However the LCM self test continued to fail.

I am encountering the same issue.
