Not sure if anyone else has run into this issue yet but ever since updating to MacOS27, sending RCS messages via my Mac Mini is not a thing for some reason.
I've signed out of iMessage on my Mac and iPhone, synced messages via iCloud, restarted both devices, verified they're on the same network but nothing has worked so far. I have no problem sending RCS messages to my wife ON my iPhone, I just can’t do it from my Mac and I'm kind of stumped as to why.
