Should my iMac hibernate instantly

I've obtained a 2009 iMac (Intel Core 2 Duo) and also I've seen that the disks never ever rest. I ran a power display and also the iMac is making use of a 3rd of our power on a daily basis!

I've examined using pmset that hibernatemode is readied to 1 and also when I actively click Apple > Sleep the iMac rests by conserving state to RAM. Nonetheless, if I simply leave the tool the screen rests yet the disk never ever does.

I've disconnected all USB tools and also seen to it that bluetooth is not permitted to wake the tool which wake - on - lan is off

maxi:~ pauldambra$ pmset -g
Active Profiles:
AC Power        -1*
Currently in use:
 hibernatemode  1
 halfdim    1
 womp       0
 sleep      2
 powerbutton    1
 disksleep  2
 hibernatefile  /var/vm/sleepimage
 ttyskeepawake  1
 autorestart    0
 displaysleep   1

I'm rather new to Macs and also Unix so I'm not actually certain just how I deal with examining what is maintaining the disks awake (or without a doubt if I've recognized just how disksleep work with a mac)

Many many thanks beforehand

Sleep can be a complicated point, Mac OS calls for that there is no disc task for a complete min after the moment you set it to rest. So somethings you might intend to examine is if the concern takes place in Safe Boot, or if there is anything gushing right into your log and also ultimately if the concern continues a new user account.

Your iMac need to instantly rotate down its disks and also go to rest.

Make use of the adhering to command to watch a thorough log revealing your iMac is power background :

pmset -g log

Look out for applications that might be maintaining your Mac awake and also energetic. Applications and also various other procedures can maintain your Mac awake if they are giving a solution, such as documents sharing or remote accessibility.

Do you have an energetic ssh session or incurable session running? This can additionally be in charge of maintaining your iMac awake.

Realize that Apple does not formally sustain hibernation on desktop computer Macs. Your setup hibernatemode recommends you have this attribute made it possible for.

Please note : I am entailed with a business item called Power Manager, it can aid make your Mac sleep more predictably.
