At this point, any items that are identified as Windows shares should disappear from the Finder sidebar. Try going to the Sharing system preferences and in the advanced options in the "File Sharing" section, first uncheck the option for SMB and then click Done. Most of the time these unknown shared items are identified as Windows-based PCs or other systems that use SMB networking. Try disabling sharing features on the virtual machine as well as the VM program (Parallels or VMWare) to see if that clears the odd shared item.ĭisable and re-enable SMB networking. If you use virtual machines, depending on how they are configured they may appear as shared systems either locally or to other systems on the network. Along with resetting the router, troubleshoot router settings by disabling any extra features (print servers, UPnP, etc.), if you do not use them.Ĭheck virtual machines. Sometimes this is because of cached machine information in the router that may still be presented to the network, and other times the router itself may have sharing features. Many routers and networking devices will appear as a shared item. After you have booted into Safe Mode, restart the system. As a basic first step, try restarting the computer, even going into Safe Mode by holding the Shift button during boot. Next, try the following options to see if the shared item goes away:

Nevertheless, there are a few things you can try to clear them. Many times these are phantom devices that appear as a result of a bug in network hardware, or in an odd implementation of a network protocol in various devices that do not usually share files. These unknown items showing in the Shared section can be difficult to track down, especially when you are on a small home network where there are only a few devices such as a laptop, a desktop, and perhaps a mobile phone. Sometimes the devices may appear as a domain name ("other times they may look like a username ("jsmith"), a device of sorts ("Netgear-343A2"), or a personal computer ("Tophers-PC-VM"). If you are on a public network or a large work network, you may see numerous unknown devices show up in the shared list, but if you are at home or are on an otherwise private or restricted network then an unknown device that pops up can be concerning. While the "Shared" section in the sidebar should only show you resources on the local network (i.e., servers, workgroups, individual PCs, and NAS devices), sometimes odd or unrecognized items may show up. The Finder's sidebar in OS X is built to allow you quick access to resources such as network shares, your home directory, and custom searches, among other locations you can add to the sidebar.
