I use my ph# for iMessage on my iPhone and it was syncing fine between it and my MBP....no longer working...I have signed out and back in with no luck....any suggestions?
Just figured it out...on my iPhone I only had my ph# listed...didnt have my email (which is my AppleID) listed...I added it and then deselected it so that it only used my ph# and it popped right up on my MBP.
