This thing has been bothering me for the past few days

I was going to guess it was someone mooching off of your WiFi, but since you have a secure password, that's obviously not the case...

You might not be able to access it by Finder, but I'm thinking you could try and see if the same device appears as a shared library on iTunes :O

 

i guess someone's connected to your wifi network. best thing to do is to access your wifi router configuration and change your security password.

 

It happened to me also, I allowed my friend's laptop to connect to my wifi network at home. I have a secure password but I added my friend's computer to the "allow" list. From then on, whenever my friend would visit me his computer name would appear under Shared. Maybe someone has gained access to your network once without your knowledge and now your network recognizes that computer whenever it is within range.

 

some1 is connected to your wifi network, if you dont know who it is just dive into the router and tick the users/allow list of clients

 

To double check if the network user is really on your network or just a "Phantom Menace of the Sidebar"... In the Finder, choose Go > “Connect to Server.” Click Browse. The computers on your network with sharing services turned on are displayed in a Finder window. If it isn't there then it may just be a remnant of a previous share that never went away.

 

We use Smart bro in the office and a lot of computers can be seen in the network. I think its the nature of smart bro. maybe your problem is similar to that.

 

This only happens if the computer is directly connected to the Motorola Canopy, since the Smart BROken system acts like one giant Wifi network. If you are connected to Smart BROken through a router, like kaloyster is, then the other users in your area shouldn't show up in your private Network.

 

@ caloyster

That means someone is hooked on your wifi access. That's typical in our office since we use wifi access as well. We could see the others in the office using the wifi. Unfortunately, our office prefers it not to protect the access so we could also see other users as well. We don't mind actually since they're only 1 or 2 users not coming from the office.

And don't worry you can't access them and vice-versa, it's password protected. In our office when we need to send a file to an associate, we use this to transfer/get files. In this process, it's password protected so you can send/receive without your password.

 

Yes, Stay connected also on.

 

I'm sorry but I can't help but notice more share libraries are being added to your sidebar.

Do post another picture after time! haha

 

I can't remember how I deleted my friend's computer name from my sidebar. Argh.

Edit: Do you connect at home via a router? What if you delete your preferred network in System Preferences - Network - Airport then join the network again?

 

open terminal type killall Finder.

 

disconnect from the network first then do the terminal command and if it did'nt work you have to remove com.apple.Finder.plist to get rid of it (finder setting will return to default though) and if for some reasons it won't go away when connected to a network it just mean that it's really connected to your network, configure your router : change SSID name, Do not Broadcast SSID, MAc Address Filtering and WPA for security, do not use WEP since it can be hack easily with right tools.

 

I think you need to reset your wifi access. The reason why that is hooking up is because you are discoverable.
