Sync my iPhone on Itunes with NAS library
Hi,
I used to sync my iphone through itunes with the iTunes library I stored on my NAS.
I have a new computer and want to do this again.
I have made iTunes able to access my iTunes library stored on the NAS, I can play the music on my computer but when I want to sync my iphone, the obly library on which I am allowed to do it by Itunes is the local library, not the one on the NAS.
How can I make the NAS library the one to use for my Iphone sync?
MacBook Air, OS X El Capitan (10.11.6)
