Hey, I juts got my new iMac 24', 2.8 yada yada yada,, And Im trying to set up my wifi so my iPod touch can use the wifi from my iMac. My iMac is plugged into my modem (cable) via ethernet cable. I know that you can use the iMac to broadcast wifi.. But I can't seem to get the settings correct... Any HelP ? I tried the System Pref/Sharing/Internet sharing, and every time I change a setting, it never saves... Any help would be appreciated..
