@Zonque The reason why you cannot ping or rsync to the Omega2 is that your Mac has no apparent route to the device. Your Mac is most likely routing everything through it's primary network connection on the 10.0.x.x network and that network has no route to the 192.168.x.x network. The simplest method is to connect your Omega2 to the same network as your Mac, that way both devices are on the same subnet and the routing ceases to be an issue. Alternatively you can add a route to yor Mac routing table. First find the name of the interface on Mac that is connected to the Omega2 wifi, use the ifconfig command to see the names, then from the command prompt of your Mac issue this command, replacing the interface name route add -host -interface <name of the interface>
