Problems with Airplay on Apple TV3 after upgrading to Sequoia 15.0

Disabling the firewall worked for me and I can now screen mirror again to Apple TV 3rd Gen 18.2 from My Macbook Pro 15.2. Issue started immediately after upgrading to macOS Sequoia 15.2. I could easily screen mirror to iPad and can also mirror from another laptop running macOS Sonoma 14.5 to the Apple TV.

Again, disabling the firewall brought back the screen sharing functionality for me instantly. Enabling the firewall (Settings -> Network -> Firewall) doesn't seem to disrupt screen sharing immediately, but it makes it so that the feature stops working next time I try to connect with a dialog "Could not connect to Apple TV"

I could see no offending rules in the Options area of the firewall.

I have found that if you disable the Mac OS firewall, airplay will work in 15.2 but with it on it attempts to connect but fails. - This is a poor solution but currently, it's the only way we can get it to work in 15.2. - it seems that there is something that needs to be allowed in the firewall settings to allow airplay to work correctly.

Having the exact same issues. Airplay\mirroring from my iphone works fine though.

same issue with my MBP with M1 chip and an Apple TV 4K with tvOS 18. it will randomly disconnect.

Also have same issue with Apple TV 4K, disconnected randomly and trouble even trying to airplay. Doesn’t even see my Apple TV sometimes.

Same issue here and its really screwing up my workflow. MBP with M2 Pro chip and 4k Apple TV (A2737).

Same here with a MacBook Pro and M1. It will inconsistently drop.

I am facing a very similar issue. I often use my Apple TV as a second display for my Mac, since upgrading my mac to macOS Sequoia 15.0 it constantly disconnects. Sometimes it works for 2 minutes, sometimes I get an hour but in the end it always disconnects. This used to work very well before I updated and it's made me want to downgrade my mac OS. I was hoping that 15.0.1 would fix it but it just made it worse and more frequent.

Come on Apple, please fix this.

The firewall is blocking us from connecting. The fix is to:

• Turn off the firewall.
• Connect to Apple TV.
• Turn the firewall back on.

Then you're okay until the next time you try to connect.

After updating both of my MacBooks to Sequoia 15.2...

• M1 MacBook Pro: AirPlay screen mirroring works fine to an Apple TV
• Intel MacBook Pro: Airplay screen mirroring does NOT work to an Apple TV. I've tried resetting the PRAM and SMC. Strangely, the screen mirroring will work to an iPad.

We are facing same issues, after updating Apple TV to 18 these issues started MacBook airplay is dropping for every 3-4minutes it’s annoying

Same issue. tsOS 18.1, MacOS 15.1.1 - I use this everyday and now it's unusable.

Any resolutions?

For me, my mac firewall has always been disabled. It seems to be hit and miss with it working.

My mac firewall has always been disabled!

I can Airplay from any device to Apple TV, but not between iPhone and iMac

I think this nightmare started when I update my iPhone to iOS 18.

Using 18.3.1 and Sequoia 15.3.
