Can HomePod play sound from my MacBook Pro

Yes, as well as AirPlay from iTunes you can set your HomePod to be the main audio source for your Mac. See the AirPlay from Mac section of How to AirPlay audio - Apple Support.

Yes - via airplay from within iTunes on MacBookPro

Good luck using it with gaming or anything else besides iTunes and Safari though.... you'll be in for a nice 1-2 second audio lag

Thanks. I was trying to find that link.
