Dear Chris,
many thanks for all your info and suggestions. For the moment I want to
test netjack2, I will definitively try the zita bridge asap.
Regarding your questions, I have never truncated the commands outputs.
Firstly, the -Cno -Pyes commands remove the warning "Default input and
output devices are not the same !!", while having only -P does not.
I have specified the parameters for coreaudio. I did various trials, I
report the outputs below.

TRIAL 3----------------------------------------------------
On the master (Mac computer)
jack_load netmanager -i "-h" gives:
Internal client parameters:
-a, --multicast-ip Multicast address (default: 225.3.19.154)
-p, --udp-net-port UDP port (default: 19000)
-c, --auto-connect Auto connect netmaster to system ports (default: false)
-s, --auto-save Save/restore netmaster connection state when restarted
(default: false)
Therefore I typed: jack_load netmanager -i "-c true"
netmanager is running.
client name = netmanager
The result does not change....

TRIAL 4 ----------------------------------------------------
I used a different buffer size 1024 and with or without specifying the
maximum number of port of jackd
jackd -P 70 -t 2000 -dcoreaudio -s -r48000 -p1024 -n2 -Cno -Pyes
jackd -P 70 -p96 -t 2000 -dcoreaudio -s -r48000 -p1024 -n2 -Cno -Pyes
The result are the same of before.,...
TRIAL 5 ----------------------------------------------------
Notably if I just us: jackd -R -d net or jackd -R -d net -a 225.3.19.154
-p 19000 or
the crashing error "Floating point exception: 8" arises, while it does not
specifying jackd -R -d net -a 225.3.19.154 -p 19000 -C 0 -P 2 (see TRIAL

Still the problems persists. I can't proceed... Any further suggestion to
make work the two jackified units?
