Could not connect to apple tv from MacOS Sierra

I have this problem as well, and what worked for me was to deactivate the Apple ID two-factor authentification.

I could finally connect to my itunes store on my apple TV 2 to access my movies and tv shows, but I still can't access the apple TV from any of my Mac on Sierra or Iphone 6 with latest iOs. Airplay is not possible between either Sierra OS or latest iOs. Such a shame.

Hi,

Just had this problem and tried many things. My iPhone streamed to the Apple TV perfectly, but my MacBook Air (2012) after updating to MacOS Sierra (from scratch) fully rejected to stream.

The problem was in the FIREWALL

Tried to switch it of and started working.

Spend more than 2 hour, was really frustrated with Sierra (lost 3 Word docs after the upgrade by simple Word "application is not responding") and even thought to get back to Maverics.

Now thinking about getting back to Windows (as I used to do 6 years ago 🙂)

Good luck with this.

Regards.

I was experiencing this exact same issue and found my Security & Privacy >> Firewall was turned ON. Turning this off restored my ability to connect to any AppleTV .

Hi. You might try this trick, Re: AirPlay no longer working MacBook Pro to Apple TV - requests code but will not work.

Here Re: Constant Apple TV 4 Airplay Drop outs on Sierra is another. Remove those old screen sharing/casting apps.

Did you get anywhere with this? I have the same issue.

Hi. This strange behavior (computer requires passcode when Apple TV doesn't) has been reported for El Capitain as well. Try restarting Apple TV and rebooting the computer. It might help, but no promises.

One further thought. Is Bluetooth turned on on your Mac? If so, could you try turning it off and see if it makes a difference? If wonder if peer-to-to-peer AirPlay is getting involved somehow.

I upgraded my iMac to Sierra and could not connect to Apple TV at all. It seemed to try (though nothing ever appeared on the TV), but would then fail with an error. I restored to El Capitan from my backup and it works fine.

I solved this by signing out from iTunes store on my ATV and on my computer and then signing back in again making sure to put the received codes in as requested. Once all was signed out then signed back in, everything worked again.

I tried that also, did not work. Repeated, multiple reboots and restarts and .... nothing. I'm belligerently staying with MacOS Sierra, Apple get on it.

Mac Laptop late 2011 worked OK, no problem. Same Sierra OS as my Mac Mini, same configuration hardware as the laptop; but Mac Mini will NOT connect ("cannot find ..") Apple TV.

My laptop (late 2011) with Sierra finally connected after several reboots and restarts (ATV). But my Mac Mini (mid 2011) with Sierra will not. Many reboots later, no help. I hope this gets resolved soonest. Use it often.

Airplay is working if I use Itunes and play a video and stream it to the Apple TV.

Airplay is not working if I try to use Mirroring. If I try to display my dsktop on the Apple TV 4th Gen. I get the message 'Could not connect to "Apple TV"'.

OS: MacOs Sierra

Device: MacBook Air 2011

Mirroring did work fine with the previous MacOS

Mirroring does work with an iPad Mini 4th Gen.

I used Onyx for Sierra (from Titanium), and that solved the issue.
