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)

I believe the problem is in the audio subsystem on the Mac. Sometimes I get a message on my iPhone and it sounds like rap music. VNC on the Mac and sometimes Firefox now crash dumps at exit AFTER I GET a message. Audio is lagging on movie play for some formats too, and Sling TV has given up altogether with their app. Look to something wedging the audio server...

Sometimes messages will come through normally, which is why this is frustrating. I'll test it... the message will come through at the the same time as the iPhone. I'll test it a few minutes later, and I'll get it on the iPhone without a notification. Then, sometimes up to 20 minutes later, it will show up on the Mac with a notification. I guess a downgrade to Sierra is in order. 😟

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.
