Apple TV 3 can't connect to shared iTunes library

dealing w/ 2 senior advisers, network engineers on this issue to isolate the issue

you just verified it's NOT Arris Cable Modems...

not sure how "Renaming the iMac" has worked permanently for several people; worked sporadically and temporarily for me..

so frustrating; am guessing you already tried to rebuild your iTunes libary?

also curious which EXTREME you are using for your router?

AirPort Extreme 802.11n (4th Gen)

Serial Number: 6F0491UCACC

This problem has been really frustrating for me since the last ATV updates.

I have 3 ATV3s and 2 ATV2s. The ATV2s have been pretty stable, but the ATV3s would not connect to my iTunes library on my MacPro running latest release of Yosemite and iTunes. All ATVs are running the latest version available to it.

Any time my ATV3 would go to sleep it would lose the connection to the library and the only way I could get it back was to restart the ATV3. That worked 75% of the time, but sometimes I would have to close then open the iTunesapp, or even reboot the computer.

Over the weekend I tried a bunch of changes to the MAC, changed computer name, library name, etc., and started running the iTunes library from an account with administrator priveleges.

Since I made this change late Saturday, I have not had any library disconnects, and the environment has stabilized again.

you using 10.10.2?

I have two identical models of ATV3 and neither one connects. At least we have a prime suspect and that possibly is the new ATV3, but not related to the software or updates.

It must reside in lower level code and configurations of the new ATV. At least that would be my initial take on it.

Yes, on both my iMac and MBP. 10.10.2

either of you reinstall OS software?

and not be able to access itunes from iphone or ipad remotes??

I have not tried reinstalling the OS on my iMac but I did restore the ATV to factory settings and set it up all over again. NO help. I literally have to come upstairs and reboot every time I want to use it, so like every day.

I have not tried to rebuild my iTunes library because I did it recently and really don't wan to go thru it again. Why do you think that would help?

total pain; have to reboot everytime I want to listen to airplay downstairs on my audio system

amazing apple engineers aren't even aware of this issue

dealt w/ 6 senior advisers and had to bring this issue and forum to their attention to pass it up the chain of command!

how frustrating! surprised more people aren't complaining...

and that itunes match ***** that you are limited to 25,000 songs; how stupid for those of us that are audiophiles1

I have rebuilt the iTunes library and that did not help, so I wouldn't go through that if I were you.

But I am going to do a clean install of the OS next. I am doubtful it will help, but have to go through this methodically and will post the results.

I have also tinkered with opening variety of ports on the U Verse router on the APV and my iMac, with no progress.

Please let us know. Thank you.

I am re-installing Yosemite as we speak. A clean install, not an upgrade. So, I will know within hours, perhaps by morning if that will resolve the issue. However, right before doing that. I tested my two Macs, one iMac and one MBP to see if it connects to either of my ATV3's. The iMac which has the latest iTunes 12.1.0.50 on it gave the same error that it can not access iTunes. However, the MacBook Pro which the iTunes has not been updated to the latest version connected repeatedly with no problem.

So, I think the latest iTunes is the main culprit, however it may not be the only one. ATV3 model along with the new iTunes 12.1.0.50 is the problem, and until they release either a patch/update for ATV, or iTunes with this bug fixed, there are no sure shot workarounds. That is if they address the problem in their next update release.

I didn't stop there, I bought and replaced my Airport Extreme

AirPort Extreme 802.11n (4th Gen)

With the new

AirPort Extreme 802.11AC (5th Gen)

So far, no difference other than the obvious which the new Airport is much more faster technology of 802.11AC, instead of 802.11N. I still have to deal with the Arris NVG589 from AT&T U-Verse (Not Time Warner)and convert it to a bridge and make the Airport the primary WiFi DHCP router, since they are still in bridge mode.

So, so far all attempts have failed, but have narrowed the problem greatly. Sorry, I wish I had better news to report.

I performed a clean install of Yosemite OS on my MBP and have had no problem with the ATV connecting to it. It is hard to tell what actually the problem is, but obviously the build up of OS upgrades on top of each other has something significant to do with it.

Just follow the standard instructions for a clean Install, after you have backed up all you data via Time Machine or otherwise, and it should correct the problem.

Good luck
