Not sure if my Macbookpro Retina 2015 is waking up from sleep, safesleep or hibernation.

I have enabled hibernatemode 25 (via terminal command: sudo pmset -a hibernatemode 25). pmset -g shows hibernatemode is indeed 25.

Is this mode the equivalent of the Windows 7 hibernate and or, the hibernate button on the 'Deepsleep' widget/mac app http://www.axoniclabs.com/DeepSleep/ or the other 'Deep Sleep' app's sleep button http://deepsleep.free.fr ?

    If you have to type your file vault password, you hibernated. If you aren't using FileVault, you should.

When you wake a Mac from hibernation, RAM got written to disk and power removed from memory. Then, at wake, it gets read back into RAM. This takes longer than normal, or standby sleep (depending on the delay set) and is visible at wake time by showing an Apple symbol and progress bar underneath (white time markers filling up). Also running the following command in Terminal:

pmset -g log | grep -i "wake from"

will show the sleep states, e.g.

Wake from Hibernate
Wake from Normal Sleep
Wake from Standby

The last time I saw the 'Deepsleep' widget in action, it did the same as hibernation, i.e. write to disk and remove power from memory.
PS. As the man pages (man pmset) hint in the quote below, standby and autopoweroff should be set to the value "0", via the same pmset command you've used to set hibernatemode, to set your MacBook Pro to use hibernation instead of normal, or standby sleep (I would also disable any Energy Saver System Preferences to wake your Mac periodically):

For example, on desktops that support standby a hibernation image will be written after the specified standbydelay time. To disable hibernation images completely, ensure hibernatemode standby and autopoweroff are all set to 0.

PPS. But please also consider the following thread here on AskDifferent:

  • Thank you for your answer redarm. The log produced shows all sleep states were "Wake from Standby". Hibernatemode is set to 25 and Standbydelay to 1. However, I still get the same results. I wanted the mac to actually hibernate like a Windows PC does. I was told macs can actually do this and is evident when seeing the grey screen (support.apple.com/en-gb/HT201635). Still trying to figure this out.

  • Btw Redarm, are you sure you've interpreted the man pages correctly? It says if you want to disable hibernation you should set values to 0, which is the opposite of what you mentioned in your PS.

  • Hi Redarm, I disabled standby via the sudo pmset -a standby 0 command. I now get the grey screen with the progress bar. Howeover, when I run the pmset -g log | grep -i "wake from" command you mentioned, the log still shows Wake from Standby...I thought the grey screen with the progress bar means waking from hibernate. According to your command that is not the case.

  • Do you have a link for your pmset manual? When I run the man pmset command I get a manual similar if no the same as this one: (manpagez.com/man/1/pmset), which doesn't have the paragraph you quoted below.

  • Did you also set autopoweroff to 0? Both standby and autopoweroff set a delay, after which the system hibernates; so to achieve hibernation straight away, they would have to be 0. With both set to 0 I see "wake from hibernation" in the log on a mid 2014 retina MacBook Pro straight away. No devices were attached - any drives attached will be ejected.
