Challenges and Workaround for HomeKit Control on Mac

The challenges of implementing HomeKit control on a Mac are due to the need for embedding a catalyst application for HomeKit control inside the app, unless the app is already a catalyst application. The speaker suggests creating a HomeKit scene to start a music playback on a HomePod on a Mac and running the scene from the Mac, as HomeKit scenes can be run on Mac OS. However, the playback destination action does not exist on Mac, possibly because the HomeKit scene hands off to the Home app, which has the catalyst stuff, but the playback destination action cannot do the same.
