Remove shared devices from my MacBook Some device is being shown under Shared section on my MacBook. I don't remember setting up any such device at all.



How do I remove this device, once and for all? Note that I am not sharing any folder, etc. Also, right clicking, etc. does not reveal any options.
The device you see under Shared section in Finder sidebar is not the computer you setup. In your case, that's a Windows computer with some form of sharing enabled.

If you do not access resources available in your local Network this way, you can choose to remove the Shared section from the Finder sidebar. Just open Finder Preferences, go to Sidebar tab and uncheck all the items shown under Shared section.
