archicad interrupted logout

anyone else notice, if you walk away from your computer for an hour or two, particularly on mac when it tries to 'go to sleep', it tries to shut down archicad? I've also left ac open over night (yeah, I know thats bad, and I don't take my own advice on this and so many other things) to find that ac is closed the following morning, with no bug report or crash recovery...

So, do you consider this a bug?

Should macOS not be able to shut down Archicad? When it shuts it down, is there work or data lost the next morning? (If you did not save before leaving Archicad.) Is there an Autosave available next morning?

it's definitely a combination of bug + user error.
Obviously, there is no reason or excuse to leave a file open over night; and even worse, forgetting to save before calling it quits for the day. This is all user error.

And I'm not sure if the OS shutting down Archicad when it 'goes to sleep' is a software feature or bug; but it seems like it shouldn't try to quit archicad.

...
I have seen lost work when shutting down for the day and not saving/closing. That is easily mitigated by simply saving and closing... but I'm only perfect when I direct/criticize/train other people's workflow & protocols; I fall short when in practice on my own 😉

The only times macOS will try to shut down a file are:

  1. File is using too much memory
  2. Install an update

Almost all mac software autosaves their state so the system can do any necessary automatic tasks.

Guess to which group AC belongs to…

@Eduardo Rolon maybe it is a memory issue... I have 128GB physical memory, and typically have 75+GB free. But I have seen Cineware eating up massive memory caches (even though I never use cinerender). I think I posted about this years ago when my older macs were routinely running out of memory with only a few AC files open, a nd I'd see Cinware taking up 5-10x more memory than Archicad. Doesn't look like its that bad on my compy now:

I usually close all files before I hibernate my (Windows) PC, but there are times when I've forgotten and left it open overnight. I haven't seen anything adverse so far. macOS issue?

This one is a mac only issue and I don't think GS can do much about it because of TW.

this happens more on .pln files than on t/w files; at least when I deal with it.
