Yes, this is related to continuity camera. It's driving me crazy b/c it chimes all the time. It even started chiming in the middle of the night the other night when I wasn't on the phone or the computer.
What I'm getting is a connection notification:
Connect to X's iMac
You can discover to remove this iPhone from the iMac microphone list.
[Pause]
[Disconnect]
It happens when I'm working on my iMac without any connected devices (other than keyboard and mouse) and also when I am using AirPods.
I tried disconnecting, which triggered a confirmation on the iMac, which I confirmed. I thought this would stop it from trying to reconnect in the future, but that's not the case.
My guess is that the phone and iMac are losing a connection at some point and then re-establishing it.
I don't actually care that it's doing that IF it were doing it in the background. But it chimes even though I have the sound switch turned off. It's very distracting when I'm on work calls (zoom on iMac), not only for me but also for the people on the call b/c the AirPods pick up a lot of ambient noise anyway. My only option is to put the phone in another room, which isn't always feasible.
Since I can't find any setting to turn off the notification or mute the Chime, I'd love to know how to turn off Continuity Camera since I don't need it.
