Vista - Cannot add Mac device

I installed folder share on my windows machine and at the end of the process,
it asks for the machine name. So far so good! Then I installed it on my Mac
OS X Leopard machine and it says that it installed successfully, but it never
asked for a machine name. When I log in and click on Devices, I only see the
windows machine and cannot find a way to manually add the Mac machine.
Someone at support suggested that I go to My Devices and the My libraries. I
tried this but there is no My Libraries section under my devices. Has anyone
else had this problem? What is the work around? Thanks so much for your
help.
