I've been reading up around sleep settings as I keep finding my Late 2012 Mac Mini in a weird hung state each morning that requires a force-reboot (it's like running Windows 10 years ago!)
I thought the "deep sleep" function was to blame but when I ran
pmset-g I got this:
System-wide power settings: Currently in use: standby 0 Sleep On Power Button 1 womp 1 autorestart 0 hibernatefile /var/vm/sleepimage powernap 0 networkoversleep 0 disksleep 10 sleep 60 autopoweroffdelay 14400 hibernatemode 0 autopoweroff 1 ttyskeepawake 1 displaysleep 10 standbydelay 4200
However Difference between autopoweroff and standby in pmset says:
With the release of the OS X Mountain Lion v10.8.2 supplemental update 2.0, a new feature was introduced to enter safe sleep after four hours of the computer being connected to AC power. This is an effort to comply with the European Energy Standards (ErP Lot6). This will only occur if there is no wireless or Ethernet activity and no activity from external devices such as USB storage devices.
I have an external USB hard-drive as the 2nd drive on my SSD MacMini as my main data drive. If this is turned off, I recently noticed the system won't boot (folder with a question mark) which seems odd for an ancillary drive. Either way, would the presence of this drive prevent deep-sleep/hibernate/standby?
- It will sleep a couple of hours fine, it's only overnight it has issues
- It generally still has lights on my connected USB mini-hub when it is frozen
- It typically "semi-wakes"; the screen recognises an active input and typically I get a black screen with a responsive mouse cursor
I started writing a totally different question but then was thinking whether my USB drive might be a culprit here or I should be looking elsewhere?
How can I tell if the Mac is is sleeping Vs standby Vs hibernate Vs deep-sleep to track down which transition or action is causing the problem?
