I'm new to the mac world, so I'm not sure how to fix this problem: The "network" icon in the sidebar of my finder does not show anything when I click on it, even though I can connect to a computer on the network via "connect to server" (apple + k). How do I fix the emptiness of this browser? While it's no problem to use apple + k, I would like to know what computers are possible via GUI. I've tried to search this subject numerous times, so either I'm not using the right keywords or the solution was never posted. Thanks.
