Q: Apple TV cannot connect to iTunes library on MacBook Pro after upgrade to Yosemite/iTunes 12

Tried all the stuff mentioned in the discussions , absolutely none of it worked!

bondbonds tip worked for me. Even without singing.

Have the same problem.   Didn't have these problems when Jobs was around!

Nothing working. Changed name of computer, no dice. This is not a small bug--it's a major oversight. How does this happen at Apple? Why is Apple not issuing instructions? Glad I did not upgrade all my computers. Better wait until they actually release a professional product.

Tell me about it.   I moved from windows because of this crap!   If I'm going to put up with this sort of stuff I should go back.  A **** of a lot cheaper!

I had to reboot the router from my ISP in order for the library to reappear after the upgrade.

Fixed. Did several things...but I suspect that my real problem was that in the upgrade the Macbook Air shifted to my guest network, thus blocking the AppleTV from view. Changing to the home network seems to have been the key. I also checked the AppleTV update (already up to date), changed the name of the computer, and did various reboots. Noting fancy, did not reset the AppleTV.

See fix below. I am now (almost) happy.

This also worked for me. Thanks

I had the issue where Music and Photos would show and stream fine.  But Movies / Home Movies were missing.  Here's what worked for me.

The App Store was showing an iTunes update which refused to download.  So I manually downloaded the update and installed.  After that, Movies / Home Movies reappeared and streamed as usual

That worked for me too. Thank you!!!

This worked for me. Just did what you indicated and all seems ok for now. Will keep "my fingers crossed"!!

Thanks

I'm having the same problem. Home sharing works fine on iPhone and iPad. On Apple TV only music works. Video keeps loading, but never runs.

Thanks to those earlier who suggested the following:

Go to System Preferences on your Mac

Click Sharing

Change your Computer Name

Once I did this everything appeared on Apple TV

Getting a bit sick of having to check these threads to sort out problems that Apple should have addressed before releasing updates that don't work!!

The second restart of the ATV did it.

Was able to watch video and air-play.

This is my first issue with my ATV. Usually it's a true soldier.
