Whom you will see and who will talk to whom depends on the OSs/Systems concerned and their versions. As a generality, OS 7.6.1 and higher see OS X 10.4 easily, and will exchange if the older system is the supplicant (client). Older Systems than 7.6.1 need an intermediary to make a two-step exchange with OS X. There are specifics at various places in these Forums. Open Transport, AppleShare, AppleTalk, TCP/IP, 'volume' size. file size and phase of the moon can all have additional effects in the mixture.
