Messages not syncing between iMac 15.0.1 and iPhone X
Not all messages sync with the iPhone 10. iMac will not allow a message to be sent or received from some people who are in my address book. Some of them have an iPhone, others do not. It seems random. The problems seem to have coincided with the recent installation of Malwarebytes.
