Messages go through on my iPhone, but not my Mac.
How do you make messages go out from my Mac. They're going out on my iPhone, my not my Mac. I'm using MacOS 12.6.5. It keeps saying "message failure". I did everything it said: restarted, checked that time and date are the same on my iPhone and Mac, etc. This is only recent. It always was fine before this.
