Sounds like a chicken-and-the-egg issue :/. If it is connected to a network, then either the router will have a page that tells you what it is (device list), or if you know its IP address, you can open a terminal window on a Mac and type sudo arp -a to get a list of IPs vs MAC addresses.

If you have a phone that can make a WiFi hotspot and a laptop then you can connect both the laptop and the unknown device to the phone's hotspot, then run a port scan on the network to find the MAC addresses of all connected devices. superuser.com/questions/12...

If neither, can you change the settings on your router? I prefer to disable some of the more skeptical/obtrusive firewall applications within my home network.
