Apple tv gen 3 with Macbook Pro (Big Sur) and iphone 12
I am not able to have the Apple TV show up with screen mirroring with any devices (listed above). I have tried all the regular things here listed in the forums...router reset, firewalls, wifi the same, restarting and resetting Apple TV to factory settings, restarting iphone, making sure all devices have the most recent updates, etc. Nothing works. I even bought a new (used) one thinking it might be a hardware issue...same thing. Did Apple make this device obsolete?
MacBook Pro (2020 and later)
