Unfortunately, I’ve been having an iMessage issue for the last few months–I can have conversations via Messages on my Mac and conversations via Messages on my iPhone. My iMessages have stopped synchronizing across my devices: no messages I send or receive on my Mac show up on my iPhone, and no messages I send or receive on my iPhone show up on my Mac. It’s like chatting with people from two separate devices, something that Continuity should have solved.
Luckily, there’s a fix. Here’s what I did.
