Intercom lets you use one Apple device to send a message to most of the other Apple devices in your house. Here’s a nice look at this feature in action:

Note that the Apple Watch gets a notification and a play button to hear the audio. Not sure why Intercom does not (at least not yet) support the Mac. Seems like Apple could send a notification to any Mac on the current network with a play button, just as they did with Apple Watch. This a “waiting for Big Sur” thing? Or some limitation with macOS?
