Mac Messages not syncing with iphone

Hi,

I can sort of explain why not the how and certainly not an absolutely certain fix.

Without any links to other devices it is possible to get what seem to be partial logins from the Mac to the iMessages server.

This leads to some iMessages that cannot be sent with no clear reason and also some "missed" incoming items.

There is not way to check your Mac is logged in other than adding someone to a New Message (first likely hurdle) or trying to Send to them (send hurdle).

The first is likely to be met with the name turning Red and claiming they are not "registered" (logged in) with iMessages.

The Second tells you the Message was "not Delivered" with a red exclamation mark.

You can then add to this the confusion about whether syncs appear or not.

Now if you Mac is set to Receive At the Apple ID and the Phone Number you should see those iMessages addressed to both.

However if one is not logged n fully you may only see incoming Messages that were addressed to one of them.

Staying with the Apple ID not logging in from above you may only be seeing items addresses to the iPhone Number.

A Buddy list Chat such as this AIM one between two account I have make it clear.

This is not possible in iMessages form the "To" spot like the picture or by mousing over incoming iMessages.

What you can do is Turn Off or Deselect the Alternatives in the Messages > Preferences > Accounts > iMessages and seeing if it happens with just one option active.

Although the Apple ID has to be logged in you can deselect it as an active Receive At ID

Whilst this may cause more missed item when testing initially it may point more clearly to where the issue is.

The "missing" items should also appear when the deselected ID is turned On again.

I've been looking at similar threads for a while now. Like many others out there I'm finding it hugely frustrating living with the gaps and lags in Messages on my Mac Pro (mid 2010). To have something ostensibly so useful and for it not to quite work as it should is almost worse than if the thing had never existed in the first place. The baffling thing is I don't experience the same gaps on my older MacBook pro (2009) which keeps perfectly up to date and in sync whilst the desktop machine doesn't seem to give a ****.

Messages – Fix Syncing Between Mac and IOS

Messages – Fix Syncing Between Mac and IOS (2)

Hi,

The Steps in short.

Turn Messages On on the iPhone (it can now send iMessages but only form the iPhone Number plus SMS messages to non Apple iPhones).

ON the Mac version add an Apple ID to the iMessages account. (It can now send iMessages from the Apple ID)

Add the Apple ID to the iPhone Settings > Messages > Send and Receive.

The two should now sync from this point on (And not earlier ones received on either device).

To Forward/Sync SMS/Text Messages you have to enable this on the iPhone ( Settings > Messages > Text Forwarding).

Setting this will cause a code number to appear on the Mac which in turn needs to be entered back on the iPhone.

The iPhone needs to be on the same LAN as the Mac (which normally means it is WiFi on your Home network)

The SMS or text Messages should now show on the Mac and you should be able to send SMS messages from the Mac when the iPhone Is On and connected to the Carrier and near the Mac (on the Same LAN).

Hello Ralph.

I find that my messages do sync between my iPhone and my Mac Pro BUT ONLY when my Mac is running and the Messages app is open. When they are not any messages sent or received on my iPhone do not show up on my Mac. I did the Apple ID setup some time ago and this is my experience.

Any ideas?

Thanks!

Jim

Hi,

I must admit to finding the same thing myself.

I am not sure if apple have presumed that for other things like Find my Phone or Back to my Mac that Macs are supposed to be On all the time now.

I certainly only have mine on when I am using them (Mostly as the G4 Mirrored Doors still sounds like a hover).

I am not sure why the change has happened.

I can't seem to identify a trigger. (other than the suggestion above)

I know lots of people were complaining about the amount of dismissing of iMessages they had already read elsewhere and this might be an effort to stop that.

It seems a bit daft though, as people also want to use the better storage space on the Mac to Save Chats.

As you can see I have suggestions but no answers for this one.

Thank you Ralph. I thought I was going crazy!
