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,


If the "sync" between devices gets broken and is not happening and is not solved in a time frame then the devices will not "catch up" later.


They will act not a new device has been added and only "sync" from that point onwards.

Hi,


Open a Finder Window and then use the Go Menu whilst holding down the ALT key.

Choose the Library that now appears in the menu list.

Navigate to Preferences.

Find com.apple.imessage.plist

And com.apple.imessage.bag.plist and drag both to the trash and then try to start Messages again.

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. 😟

So I tried this and it seemed to work for an hour or two, but then I got another text on my phone (from another iPhone user) and it didn't show up on my Mac running High Sierra for several minutes. My other mac, running Sierra, showed it pretty much right away.


So while this seems to help, it doesn't totally fix the issue. The only thing I haven't done is upgrade my 2nd Mac to High Sierra.


Anyone else getting someplace with this issue?

A refresh doesn't do anything at all. My messages experience has been horrible since upgrading. iMessages give zero alert. I have my phone sitting next to my macbook and neither notifies me when i get an iMessage. I have to manually click the home button to see if I have received any messages. Only when i shut down the macbook does the phone start responding with sounds + vibrations.


Also, my messages app constantly asks for passwords to my GTalk/Jabber accounts. Horrible

I tried it, and went a step further by signing completely out of iCloud on both devices as well, and it doesn't help. It will work fine at times. When it doesn't, the messages do come through eventually. I have noticed that when I use any app that checks my location, such as maps or the weather widget, the delayed messages come through immediately after. So, I don't know what's going on, but I do know that signing in and out of iMessage on the Mac and the iPhone doesn't work.
