Hi all, I have an ethernet connection and I want to use internet sharing feature on my mac. In system Pref -> Sharing -> Internet sharing, I can see a message saying internet sharing is on. But the drop down for "share your connection from" is empty. Its actually greyed out completely. Same with the field "to computers using". This field has wi-fi, firewire and etherner listed but they're greyed out. How do i enable them? Is it some permission issue?
