Home Sharing stops working with fast user switching
I have a late 2013 iMac running Mavericks. The main account has my iTunes library with Home Sharing enabled. The AppleTVs and IOS devices can see the Home Share and it works well. But, it stops working when user accounts are accessed on the Mac.
For instance, as soon as I select "Login Window..." from the fast user switching menu, the share is lost. I did not log out, iTunes is still running. I simply showed the login window. All IOS and ATVs loose the share. Switching to another user also stops the share. It's as if iTunes is completed halted and not allowed to run in the background.
When moving from the login screen back to the user account where the iTunes library is located, the home share is restored. Likewise, moving from a 2nd user account back to the main account where iTunes is runnning restores the home share.
I have a MacPro running Mountain Lion, and it works fine. The iTunes library is always available for the devices, even if multiple users are signed into the Mac, or if the Mac is on the login screen.
Any work around for Mavericks? It competely breaks the entire media ecosystem if every device looses the home share if someone tries to use their account on the Mac.
iMac, OS X Mavericks (10.9.1)
