I've been on Lion on a new iMac for 2 days or so, but each time I restart, there's always 5-10 'users sharing this computer', even as this is the only computer on the network. I have screen sharing turned on, requiring password, and files sharing turned on, but only sharing my 'Shared Folder'. I've attached a grab of the dialogue box showing 10 users connected. I don't want people snooping, but I don't want any overzealous firewalls or security software getting in the way. I use an iPad with home sharing, and an aTV 2 in the living room with aTV flash installed. Thanks for any help in advance, Tom PS: The aTV can browse the full hard drive of this iMac, even though sharing only has the Shared Folder enabled. related?
