Apologies for not providing any update for such a long time.

OK, SMC/NVRAM etc. done and reset, problem still persists.

System does go to sleep when a user is logged in; it is ONLY when users are logged out (i.e., the login screen shows with user icons displayed) that the system does not go to sleep.

And even in that screen, if I actually click on "sleep", system does go to sleep. It is only in the idle time that the system stays on and does not sleep.

And yes, I have spent more than two hours chatting with Apple USA and Apple India, and they all keep giving me the usual "What do you have in your Energy Saving setting" stuff that I have progressed way beyond.

And Apple USA - a senior tech - told me that they have never seen such an issue until now, ever.

Cheers

Unfortunately, and going by many comments at several Mac forum sites, the Apple tech support has been going downhill drastically and some of the answers they provide are nothing more than BS.

Sorry, it doesn't help your situation, but I just thought I would mention the fact of what I have been noticing.

Have you tried changing some of the Users&Groups preference pane "Login Options"???

I looked there too, but nothing seems to show that might appear related to the issue.

Rereading your original post, and checking some of our Macs, I would say that your back is working normally when using the Logout function.

If you want the Mac display to go dark, use the Sleep Function.

As far as I know, it's been that way for many OS X version years, unless of course some third-party utility is being used that might change things.

PS: Using the "Logout" function may cause your display to go completely black, which I understand is what you are wanting, ONLY IF you only have a single user.

None of our Macs have that setup and I'm not going to try changing it just to try doing such a test. Sorry.

It seems to me that the solution for your problem is to just change the way you do things and also consider the old memory department maybe failing. It does that with all of us with age, but I can't remember why!!! ;-)

Thank you Patrick

Well, if what you say is how it is, I have an update and a question for you:

I was on the phone with Apple all of yesterday afternoon and evening. And in the evening, with no changes of any kind, after I collected logs etc. for Apple per their instructions, I logged out, and when i came back, the iMac had indeed gone to sleep - screen off etc.

I wonder how and why it started working all of a sudden.

And a little later (after I had woken the machine up) and then logged out again, it did not go to sleep at all for three hours. My wife was about to login and informed me that it had not gone to sleep. Just as she sat at the machine, it did go off to sleep, and she had to wake it up again!

Very random behaviour.

And I am positive that Macs indeed go to sleep when logged out, even with multiple users created; because my iMac used to.

Cheers

Tilt, a further thought on testing....

Consider unchecking all options in System Preferences --> Software Update. This is the part of Mojave that checks back to Apple's servers to see if there are updates to be found, downloads OS updates in the background (if enabled), etc.

Also - have you checked under whichever account on your Mac has Admin privileges, if there are no other system-level daemons doing similar checks / cloud activity / anything that might require a network access?

And - again in an Admin account - Energy Saver does not have "Wake for Network Access" checked, correct?

You could be quite right, but having random behavior or intermittent occurrences is going to be very difficult to track down, after all there are so many settings and things that could cause the problem besides the normal file sharing and other network settings.

It's not foolproof, but you could try booting up in Safe Boot Mode which should disable any third party software from running and see if the problem exists or not. That would at least give a hint as to whether some third-party software or the Mac OS is causing the problem.

Even some file sharing software like Transmission.app or Fetch.app can try and keep the Mac awake.

There are just so many variables that need to be checked out.

By the way, what exactly is your main concern and why such a concern over what you expect should happen????

And what are you expecting to happen when you do do certain actions???

Logout ≠ (always) cause display sleep but logs-out the user.
Sleep = always causes display sleep but does not log-out the user.

Thank you CM.

Re. Software Update, all boxes are checked on. Do you believe that would cause the machine to not sleep? But like I sid, the Mac has been going to sleep properly the last couple of days. Weird.

"Wake for Network" is checked on. It has always been checked on. And, over the last couple of nights when the Mac has been asleep, just to see how this setting affects anything, I have tried logging into it remotely from my MacBook to, say, copy files from the iMac to the MacBook; and the machine did not wake up - the screen remained dark. So, maybe the machine wakes up in the background to serve files, but the display still stayed off.

Thanks again Patrick.

File Sharing & Printer/Scanner Sharing have always been turned on, no new changes.

Safe mode - no, I have not tried it; reason being I did not believe at that time that anything would be running inn the background, considering no user was logged in at all. However, I can try it now; but it may not provide any new information because now, weirdly, it has started to work properly normally! I have to wait for the issue to manifest itself again and then try Safe Mode.

There is no main concern or worry at all; I am merely curious as to how something that worked fine suddenly conks for no apparent reason. I guess it's some weird form of OCD that I cannot relax until I find the cause or something maybe. LOL

Cheers

Be aware that some things may not work properly when safe mode is enabled, printing services maybe I know a few other things I can't recall that are Mac OS X based, and also be aware but there can be all kinds of little bitty background processes happening whenever the computer is actually turned on.

The only time it truly close to being dormant is when it is shut down, and even then it's not always 100%: Battery trickle, standby mode waiting to be woken up, background Network processes Etc....

My Macs are all set to "never sleep" etc. When I want them to sleep, I just give a manual command for them to do so.
