After updating to macOS Sequoia I cannot send or receive iMessages on my MacBook Air.
I have made sure Text Message Forwarding is turned on on my iPhone, I have checked to make sure the time and date are accurate, I have signed out of the Apple Account on iMessages on my Mac and signed back in... I have done all the troubleshooting I can and still nothing is working. It is only since updating to the "new" macOS that I have experienced this issue.
MacBook Air, macOS 15.4
