Apple Messages Is Driving Me Crazy...

[whirl]

I shutdown my Intel iMac every night at 11pm
When I turn the iMac on again the following morning and fire up Messages App, it doesnt show any messages which have come through during the night when the iMac was shut down.

When I open the iPhone, all the messages are there sat waiting but they never come through to the iMac no matter how long I wait.

While ever the iMac is turned on, if someone sends a message I get it on both devices which tells me all the settings on both the iPhone 11, iMac and Apple iCloud must be correct

So to me it sounds like when the iMac has been shut down and turned back on, its not fetching any messages from the Cloud.

Has anyone else had this issue?

Do you have iMessages in the cloud enabled?

I am pretty sure I have all those setting dialed in but I will double check

FWIW, I went through a period a while back wherein if my iPad Mini was shut down, it would take literally days for Messages to sync up from my phone despite Messages in the cloud enabled. It somehow resolved itself over time, so probably a back-end problem at Apple.

Same thing happens on my iPad or iPhone if they've been off for a while (and yes, Messages in iCloud is turned on). I figured that's just the way it is since it has so much to catch up on when it comes back online (ex. checking if there are system updates, checking to see if there are any bookmarks, contacts, photos, notes, reminders, calendar, passwords, messages, emails, files, etc., to sync). It's not going to do all those at once; otherwise, it'd bog down the system. In my experience, they do eventually sync when it's been idle for a while.

Perhaps instead of shutting down, put the Mac to sleep...and turn on Power Nap. A sleeping Mac should not use more power than a 5W night-light bulb.

Turn Power Nap on or off on Mac

Choose whether Power Nap is on or off when your Mac is connected to a power adapter or using battery power.

This happened to me for a while.

The solution (you have to do this each time, unfortunately) is to go into Settings/iCloud on the phone, select "Messages in the Cloud" then click "Sync Now".

Then, after waiting a few minutes, open Messages on your Mac and in Preferences do the same. Usually, that brings them all over.

5-7W seems a good estimate.

Apple only notes idle and max power consumption:

However, someone here (i.e., MR Forums) tested there M1 iMac power consumption:

I don't have Messages in the Cloud enable. But say that my Mac lose its Internet connection for whatever reason or is off. The messages sync nonetheless when the device comes back online. I think that messages syncs whether you have Messages in the Cloud on or off, as long as the option to forward messages from your iPhone to your devices is enabled. I just think that it might take a few minutes for everything to get synced.
