unknown device on my Mac's network

When I browse my Mac's 'Network' in Finder I find a couple of devices unknown (to me), in addition to my printer. No idea what they could be. How do I either investigate them or remove them?

Very little info available in the Get Info panel.

Any clues?

iMac, macOS 10.12

Start by making a list of everything on your network... and I mean EVERYTHING.


You'll be surprised how much there is that doesn't come to mind immediately if you're like most.


In my house that would be 3 TVs, 2 Apple TV's, 3 Fire Sticks, an X Box, Playstation, 5 iPhones, Thermostat, doorbell, 4 laptops, 2 desktops, some Nintendo thing my daughter has, a CPAP machine, the garage door opener, 5 security cameras, 3 printers, Windows VMs on several machines that each appear as their own devices, 2 Apple Watches, and I'm sure there are more that I'm not thinking of at the moment...


Check your router to see what's connected, and go through the house turning off everything you can think of until you identify the culprits.
