I have a Fusion Drive in my late 2012 iMac and I have noticed a different sleep behavior compared to my previous 2011 iMac. i now have a sleepimage of 2 GB and a dozen swap files in /var/vm/ although I have enough memory (24 GB). I have seen these reports too for the Mac Mini and the MacBooks. It appears to me that this has something to do with using an SSD. According to pmset hibernation is disabled but there is a sleepimage: Code: #pmset -g Active Profiles: AC Power -1* Currently in use: standby 1 powerbutton 1 womp 1 halfdim 1 hibernatefile /var/vm/sleepimage autorestart 0 networkoversleep 0 disksleep 0 sleep 45 autopoweroffdelay 14400 hibernatemode 0 autopoweroff 1 ttyskeepawake 1 displaysleep 10 standbydelay 4200 Do late 2012 iMacs without a Fusion Drive behave the same?
