I just upgraded to 10.6 from 10.4 on my iMac. But I also got my son 9yo a Mac Mini, his first computer. His is also upgraded to 10.6 A friend gave me the older mushroom shaped Airport Extreme. I got my son's Mac Mini to access the internet wirelessly with it. I could not explain now how exactly I did it, I just followed the screens and kind of did it on the fly. But his Mac Mini is surfing the internet just fine and good speed. But I have an external HD with pictures on it which is firewire connected to my iMac that I'd like to be able to access wirelessly from my son's Mac Mini. Is there a way to access files from one Mac to another with the Airport Extreme?
