I have a PowerBook G4 and an iMac G4. I am trying to connect them via a normal standard ethernet cable so I can share files on them. But it doesn't seem to let me. I go into System Preferences and click on "Personal File Sharing." After that I go to: "Go" in the menu bar > "Network" but the other computer doesn't appear there. What am I doing wrong? EDIT: My PowerBook is appearing on the iMac but the iMac isn't appearing on the PowerBook. What am I doing wrong?
