Using the method outlined in Canadian Thomas's posthttp://forums.crackberry.com/blackberry-playbook-f222/mac-users-stream-itunes-library-any-folder-playbook-os7-681560/.
I was able to stream music. Folders etc from primary hard drive . However I have been unsuccessful in doing the same for a directory on 2nd internal drive using this method. I cannot create a functioning alis or link and repairng the link does not work here is the terminal command i have been trying to use in Leopard
Found the answer on my own , & I thought it might be helpful to someone else. The terminal entry for home folder , or primary drive I guess , requires a ~ symbol. This is not required when referring to other internal volume and i would suspect external drives as well so the command should read as below instead.
