Hi friends, I’m attempting to mirror my M2 2023 MBP (MacOS 15.2) to my 4K AppleTV (TVos 18.2), but it’s failing. When I initially attempted the connection I was prompted enter the PIN that was displayed on the TV into my computer, which I did, but it never successfully displayed. Since then ever time I attempt the connection it fails. I’ve rebooted both devices but still get no love. Any hints or suggestions to resolve the issue?
I had the same failure when I tried to mirror my MBP (2021 M1) to my 4K Apple TV (1st Gen—18.2) over Christmas. I also tried turning off the firewall, but it didn’t make a difference. I have been able to regularly mirror successfully in the past. This was the first time I tried since updating to Sequoia.
It seems that Sequoia has difficulty finding some devices on the local network. I couldn’t connect (see and mount in Finder) a Sequoia Mac to a Mojave Mac until I ran a 3rd party app that had previously connected. Maybe the same is happening with the Apple TV.
Some things to try:
a) connect the Mac and Apple TV using ethernet, not wifi (or vice versa!)
Update: Mirroring my M2 Macbook Air running Sequoia is working so I cannot test those tips. I installed the CiderTV app out of curiosity but it was unable to connect to the ATV with Bluetooth so that might be a Sequoia limitation.
The problem is fixed in MacOS 15.3. I had turned off the firewall on the Mac (previous workaround). After installing the .3 software updates on both devices, I turned on the firewall on the Mac (System Settings>Network>Firewall), restarted both devices, and tried mirroring. It worked.
