On your OS X Mac, go to the System Preferences and choose Sharing. Then click on "Allow FTP Sharing" to enable it. Make a note of the IP address in the bottom section.

Now, go to your 9.1 Mac and fire up Vicomsoft FTP Client or Fetch and Connect to the OS X Mac using the IP address as the host and your "OS X" username and password.

You can now move files between the computers MUCH faster than you could using AppleShare. I hope your results are as good as mine.
