iMessage Delay High Sierra

Receiving messages on my Mac are now extremely delayed since installing High Sierra. They will show up on my iPhone, but without a notification so I can't see or hear it. Then several minutes later it will pop up on the Mac. I didn't have this issue with Sierra, and would rather not downgrade. Anybody else with this issue or suggestions on how to fix this?

Mac mini, macOS High Sierra (10.13)

Hi,


Test form iPhone to Apple ID on two Macs, one High Sierra and one juts Sierra.


Arrived at the same time as far as I could judge whilst trying to see two screens.


What have you tried so far ?

Hi,


Several thread mention iCloud sharing for iMessages and this may be effecting the server speed at time if it is happening as I can find nothing so far in anything I have read. (That might juts mean I have not found it yet).

Hi,


It seems the iCloud sharing part is delayed in releasing it in Messages (so it is not that that is holding the server up)

Hi,


Yes I have issue with the Apple ID site and once recently logging in here from my Sierra computer (err it been doing alright for at least a year).


The issue I have is that all devices Bong but the six digit code only appears on one device and in some cases the device that is doing the fresh login.


However that is different from iMessages themselves being delayed.

Hi,


The key might be the first line where the iPhone App is turned Off.

This cuts the login to the server much more definitely than just signing out the Apple ID on the iPhone.


Then he (presumed) deselect the iPhone Number on the Mac version before then signing out on the mac version


At the 4th line of re-enabling the app on the iPhone does mean waiting for the Number to Verify.

I would throw in a test at that point

On the iPhone Manually type in the Apple ID used on the Mac.

Sign the Mac version back in and then send from the iPhone.

At this point the iPhone can only use the iPhone Number and the Mac only the Apple ID


If that works add back the Apple ID to the iPhone.

Accept the pop up on the Mac so the iPhone Number is accepted.


Reset Text Forwarding if required.

Hi,


Did you do that the way korn.body describes which involves turning the App Off on the iPhone as well as Signing out on the Mac ?


Basically he (?) is suggesting starting from scratch.

Hi,


If that were the case you would get the first notification and that would not play the sound for New Message Received and then it might hang.


The app has sounds but they are played by Notifications when events happen.


The AppleScript to speak event does not work as the AppeScripts themselves have not been updated

Hi,


That's what I thought you meant the first time.


However the Notifications Pop up appears before the sound is played.

Ergo the iMessages are not getting to the computer in the first place.

Hi,


This was in Message 7.0.x

User uploaded file

Changing the Location added info to the "madrid" .plist:-

User uploaded file

In both version of Messages 8 the OS passed this info to the .plist


In version 9 is less clear

In Sierra (version 10 for Messages) the location info in not passed across and the "madrid" .plist is not used any more.

Deleting it to try and refresh things does not have it recreated on restarting the app.


As you can see in the second picture the +44 for the UK is in the .plist

It adds (or rather did add) the +44 where needed. (Any Contact's info that does not have a Country Code is presumed to be the one local to you).


Some have suggested that it might default to +1 for the USA but I have not seen this myself.


Ergo Location has everything to do with why this does not work.
