I have just gotten a new update on my samsung tv 2018 version, there is additional menu "Airplay settings", however although its "on", my mac doest detect the airplay display. Both mac and tv are on the same WIFI as I can use chromecast.
I have tried to plug off the tv and turn on again, still the same, I am on update 1251.
TV Model : UA49NU7100
Solved! Go to Solution.
Searching online didn't yield any result. I promised I'll come back here if I'm able to fix it, and I did.
The problem was that I had the MacOS firewall enabled, blocking incoming connections.
What made me realize it is trying to cast from iTunes, which resulted in a more friendly error saying "your firewall is on".
Since this is a company laptop, I had to be a bit creative and disabling it, from the terminal type:
sudo /usr/libexec/ApplicationFirewall/socketfilterfw --setblockall off
and type in your password.
Works immediately, have fun!
My advice is to buy LG. If it's still possible to return, DO IT IMMEDIATELY! Sorry. I haven't found an answer, update to the software, any guidance from Samsung. Nothing. I'll remember their customer service, also. I'm sorry you are in the boat I am in. Good luck.
