iMessages on MacBook
Hello everybody,
I just recently bought a new MacBook with TouchBar.
Since then my messages app does just show Phone Numbers instead of the contact information. Also, I can not start new conversations. It always tells me that this number does not support iMessage.
Does anyone know this problem?
Thanks
Claudius
