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

Had the same problem after firing up my new iMac. The solution mentioned above by watchdog worked for me with one extra step.

1. Change the name of your computer. (System Preferences->Sharing)
2. Then restart your AppleTV.

Then it saw and connected to my iTunes!

Thanks iwatchdog!

Thanks 1watchdog. Great tip.

DDoing exactly this worked for me, thanks so much!

I'm having this problem as well. I'm actually so frustrated that I'm considering getting rid of the whole Mac line up. Each time I attempt to use Apple TV it takes resting everything before it operates. Who wants to waste 15 minutes trying to make this work each time?

How is this setup any better than Microsoft??

Frustrated & tried it all !!!!! to get home-share working on apple TV since Yosemite download. Read most of the post and nothing has worked for me. I have

Apple TV model A1427

Apple Tv software 7.0.1 (6912)

Itunes 12.0.1.26

Mac OX Yosimite 10.10

IMac

Change name of computer

Change name of ITunes library

moved ITunes library

signed out of iTunes & used new login in ITunes and home sharing

reinstalled ITunes

reset apple tv

Turn of modem and rest

turned of computer and restated

deleted library and moved to external hard drive

I have 2 apple TV one shows my I photos & one shows stock photos.

Any suggestions of what else could work.

A Stab in the dark, but see if your proxies is enabled. If so. Disable it. See if that works. It worked for me.

ive been having the same connection issues to my library on my iMac . What I found helped but don't know why, was despite my ATV and iMac being connected to my network via Ethernet I had to switch on wifi on my iMac for the connection to be successful. It makes no sense, but the only way the library will connect to the ATV, despite Ethernet being used at both ends.

Juse doing a me too On here. I found after Yosemite including on my new retina iMac that my library could not be found. I have always had iTuneS Connected on my imac by Ethernet and the AppleTV by Wi-Fi. The only way I can find my library is to toggle the Wi-Fi on the iMac on and off and it would find it. The soon as I rebooted once it would not worK again. I'm not sure what it was about toggling the Wi-Fi. I took the suggestion someone had him here to change the computer name in system preferences and that seems to have solved permanently. Thank you for that.

Restore of Apple TV in combination of renaming of macbook name has worked fine to me.

Thanks for the tip - I did this and now every time I open my computer on the Apple TV I have a new Library. They just repeat the same library for each time I open Apple TV. Anyone else encountered this?

That worked for me: updated computer name via system prefs and problem solved. Thank you itwatchdog!

Pretty janky that you have to do that IMO though. Shame on you Apple to do this within your own ecosystem!

Further, I've noticed a significant slow down on my late 2012 27" iMac w/ 16GB of RAM and a 3.4 GHz i7 processor after updating to Yosemite.

I spent 5 hours on the phone with Apple Care to the point of erasing my hard drive and re-installing everything on my iMac and MacBook with a support tech. My house-mate spent 4.5 hours on the phone with Microsoft tech support to do the same thing to his computer. My Apple TV will connect to the internet, but will not connect to my home sharing network. I, then spent 2 1/2 hours on the phone with an AppleTV support tech that resulted in completely restoring my AppleTV device. They sent me an email link to Apple TV: TCP and UDP ports and protocols used - Apple Support..

After spending almost 6 hours over the last 3 days on the phone with ATT U-verse tech support trying to get theses "ports" opened on the ATT router, I am done trying to get this fixed. They want to charge me $15 per month to have these ports opened under a 1-year contract. Apple personnel are not acknowledging a problem with Yosemite for this and a couple of other problems I am experiencing. I'm sure they will fix whatever is going on eventually. Guess I'll go outside, play with sticks and kick rocks........
