Q: My Messages stopped syncing from my iMac to my iPhone.  What can I do to correct this?

Hello David L Gerber,

Thanks for asking your question here in the Apple Support Communities. Looks like you are having an issue with your Messages. Seems that you receive them on your Mac, but it is not syncing to your iPhone. I am happy to provide you some information to get this important feature working properly again.

The first thing you want to check is that your Apple ID that you use in the Mac Massages is linked to your iPhone. You can do that by using this help article from Apple: Add or remove your phone number in iMessage or FaceTime on your iPad, iPod touch, or Mac

The second thing you need to verify is all the settings for Continuity, and SMS specifically. This help article will help you go through all the settings: Use Continuity to connect your iPhone, iPad, iPod touch, and Mac.

Thanks again for giving the Apple Support Communities a chance to help. Have a great rest of your day.
