7.5.3 and later File Sharing
Any Mac running 7.5.3 or later (with at least OpenTransport 1.1.2 and AppleShare Chooser extension 3.7.4) can share the files of any Mac running OS 9 or later using built-in File Sharing using IP. What is not supported beyond 10.3 is File Sharing via AppleTalk. In addition, Sharing initiated from your 10.4 or 10.5 Mac to a Mac before OS 9 is not supported directly. So you will have to make the connection from the Older Mac end. Alternatively, you could install "Shareway IP" (a low-cost utility) on the older Mac and connect from the newer Mac.
You need an appropriate Ethernet connection, and each Mac must have a similar (but not identical) IP Address. On the 10.4 or 10.5 Mac: You must turn on File Sharing in your 10.4 or 10.5 Mac:
System Preferences > Sharing > Services pane > \[X] Personal File Sharing
and click ( Start )
Look up the 10.4 or 10.5 Mac's IPv4 Address in System Profiler OR Network Preferences, and write it down for later. It may resemble 192.168.0.6
On the Older Mac: open the Chooser and select AppleShare. Your 10.4 or 10.5 Mac will NOT appear in the right-hand pane, because it does not speak AppleTalk File Sharing protocol. But do not despair!
It can speak IP protocol, if you ask it nicely. So click on the "Server IP Address" button on the bottom of the right pane, and enter the IPv4 Address of the 10.4 or 10.5 Mac.
The login screen that appears is sent to you from the 10.4 or 10.5 Mac. Enter a Username and password that is valid on the 10.4 or later Mac. Choose the drive(s) you want to mount, if there is a choice, and they will appear on the desktop of the Older Mac as shared Network Drives (Drive Icon with a cable coming out the bottom).
Drag whatever you like to the newly-mounted drive. It will appear on the 10.4 or 10.5 Mac. Try to resist the temptation to drag your whole drive all at once. Move smaller batches in a thoughtful way, and you should have no problems.
