Mac Messages app showing phone numbers not names
I am having the same issue that is in this thread: Mac messages show phone number and not co… - Apple Community
But I was unable to add to it.
My problem started when I upgraded to Ventura 13.1 and it is intermittent. Many people who respond to these queries assume we are all using iCloud and some of us are not.
This problem is not earth-shattering but it is annoying so if there is a fix I would like to know. It seems to only happen on my iMac. My phone and iPad are fine.
Any ideas?
Thank you.
iMac 27″, macOS 13.1
