Question: unknown shared computers in finder
i have an iMac that runs el capitan 10.1.6 early 2009.
lately i noticed that i have 1 and now 2 shared computers listed in "shared" on finder.
i can't erase them or do nothing about it?
does anyone have any informationn regarding that problem? has anyone encountered with that problem before?
iMac (24-inch Early 2009), OS X El Capitan (10.11.6)
