I just update to Big Sur and Airplay to Apple TV is no longer working. Get message that I cannot connect to AppleTV. I have tried all of the troubleshooting advice including same WiFi network, Firewall settings, rebooting routers, modem, appleTV. Any suggestions.
iMac 21.5″ 4K, macOS 11.0
Same issue and fixed it. I had same issue. Upgraded to Big Sur and then was suddenly unable to screen mirror to any of the 3 Apple TVs. I would get a message "unable to connect". As someone suggested, I needed to "authorize the computer" by signing into iTunes or Apple TV app. Once I signed in using Apple ID and Password, on the computer, I was now able to screen mirror to all Apple TVs.
If you have Norton 360 then there’s your problem, contact them, maybe if more people do that then Norton might sort it out. If you don’t have Norton it still might have something to do with your Firewall
I'm with Scutman7. If you turn off Vulnerablity in Norton, Airplay works, but you're exposed. Try it if you feel lucky. I complained to Norton again today and trashed them in a customer satisfaction survey, but I don't think they're listening.
Have you got Norton 360 antivirus software? That seems to be the problem with mine. Trying to find a work around without having to disable every time.
Ketof, if you don't solve yet, this problem "connect macbook to apple TV"with macOS Big Sur, you must just go in Settings at Apple TV, after to System, and last step, Restart, and after will WORK :D
Sorry, it's not the wifi icon, it's the control centre icon to the right of the wifi icon
click on it and it opens up a control centre, screen mirroring is in the menu
OK, success, once I had disabled the Norton 360 it worked. So the thing going forward is is this what you do to get it to work every time, or is there a work round?
Do a restart from the Apple TV and it will work. Open Settings on Apple TV, go to System and select Restart.
Try AVG, tried the free version and it all works, paid for standard version, still all works. Something to do with Norton
I've had this problem when trying to stream my library via Apple TV. Keeps telling me I have to be logged into the same Apple ID. I run a VPN app on my Mac. I found that I can only steam if the VPN is running. If I turn it off I get the error message again. Don't know why.
Restart Apple TV :D, if you dont try yet, Setting - System - Restart
Easy fix: System Preferences then Sharing. Turn on Home Sharing. That's it
Big Sur by default starts with the firewall ON. In order to use Apple TV and Airdrop, the firewall has be be OFF.
Had same issue after reading a lot i found out that once u sign in and authorize ur device from itunes then it will ask u to turn off ur firewall, whenever u turn that firewall off then go to the itunes upper right corner and use that airpmay icon to select ur samsung tv, then it will ask u for a password which u will enter on ur samsung tv:
settings> General> apple airplay settings> then turn airplay on> require code (use password instead) and exit out,
of u could t still connect it u have to go to ur laptos upper right corner contol icon, seect display preferences > on the bottom it says airplay display and choose the samsung tv from it drop down menu.
this worked for me and i hope it helps everyone else as well.
Try adjusting your firewall preferences in System Prefs. That worked for me.
After downloading macOS Big Sur my Mac doesn't connect with Apple TV and I must restart to open existing files
Cannot connect to AppleTV after Big Sur update
