I can't select anything from the Manage tab drop down menu on my Mac desktop controller

the controller is not the issue it is the library. I cant access the 3000+ songs on my itunes through Sonos. Unless your telling I can through a mobile phone controller?

This thread is about greyed out options on the Mac controller. Presumably you have the same problem. The controller -- or more specifically the operating system -- is therefore very much the issue.

If you have an outdated operating system the Manage options won't work. You can use other controllers, such as on a phone or tablet, to configure your library settings.

thanks - the phone controller works but has issues when I try to sync the library
