connect iTunes on new macbook to apple tv 1st gen. library
On my formar macbook I had iTunes to synch with Apple TV 1st generation.
After upgrading to a new macbook pro with iTunes 11.0.3 I observe following problem:
1. on apple tv 1st gen. the library from my old macbook is there but in light gray, i.e. not connected to new macbook
2. when connecting new computer to apple tv 1st gen. it will create a new library (instead of connecting with existing library).
3. in iTunes, Devices Apple TV, only buttons "Settings" and "Photos" appear on top of window. "Music", "TV-shows" are missing.
How do I connect the two libraries, i.e. iTunes library on my new macbook with library on my apple tv 1st gen (last synched with my old macbook)?
Apple TV, OS X Mountain Lion (10.8.3)
