Tim Hardwick, MacRumors:

Intercom will enable family members to communicate with each other wherever they are in the home, with the ability to send and receive spoken messages via HomePod speakers. If a family member is in the garden or away from home, they can still use Intercom on their iPhone, iPad, Apple Watch, and even CarPlay.

No mention of Mac there. From Apple’s official HomePod mini release, in the section called “Smart Home Controls and New Intercom System”, there’s no mention of the Mac.

An oversight? Intentional omission?
