I have an issue I would really appreciate help with. Whilst using VMWare fusion, I came across the dialogue box " Would you like to enable sharing of your Home folder on your Mac?" and accidentally clicked "yes" . Subsequently a connection appeared under " sharing" in my finder window that appears to refer to the VMWare partition.
There is also a connection that shows up that appears to be referring to a laptop I have on my home network that has NEVER been set to share files with my Mac.
Do you mean "SHARED" on the Sidebar in Finder?
If yes then this is an OS X Finder feature and you should consult the OS X Help File and or Apple and or OS X centric forums for a solution to an OS X feature issue.
