    Hi guys, I've got 2 27" iMacs. late 2012 and late 2013 models. They are both on 10.9.5.

    One of them (2012) has the "computer sleep" option next to the "display sleep" option, in System Preferences. The 2013 only shows one of them...

    Why is this? I really like to have the 2 options...

    Thanks for any help.

    Macs with newer Intel chipsets (Haswell and up) that support a new low power state do not show the sleep option. They just enter that low power state instead of sleep.
