Dear all

I attempted to create a network in my mac and connect another mac to my network. Connection was succeed and both mac received a self-assigned Ip address from this network(computer-to-computer network). Then I setup my code like this:  
my mac

```auto
OscP5 myMac;
NetAddress otherMac;
void setup(){
    myMac = new OscP5(this, 32000);
    otherMac = new NetAddress("169.254.163.96",12000)
    OscMessage msg = new OscMessage("/hello");
    msg.add("hello");
    myMac.send(msg,otherMac);
}
void draw(){}

```

Other mac

```auto
OscP5 otherMac;

void setup(){
    otherMac = new OscP5(this, 12000);
}
void draw(){}
void oscEvent(OscMessage msg){
      if(msg.checkAddrPattern("/hello")) println(msg.get(0).stringValue());
}

```

I run these code each one in the correspondent mac and I don’t receive any message.  
Is it possible to use OscP5 with this kind of network or there is some tweaks I need to do in the mac preferences.

Thank you in advance

It has been a while, but I don’t think those OSC ports are open on your Macs by default? Last time I was doing mac-to-mac OSC a few years ago I _believe_ that I was using OSCulator to route the messages, which should still be up to date with the latest MacOS. (untested)
