    My 2013 27" iMac running 10.12.2 is refusing to sleep on its own. Based on "pmset -g assertions" and activity monitor output, hidd seems to be the culprit. I am using BT Apple keyboard and mouse.

    Even when I put it to sleep manually, the Thunderbolt Promise Pegasus R4 RAID array doesn't shutdown automatically, the way it used to before. This problem might have started a few months ago even before 10.12.2 update.

    The only changes, I can recall since it used to sleep without issues are as follows:
    - Apple replaced the internal hard disk of this iMac under one of the replacement program.
    - Upgraded to 10.12

    I have already reset SMC and deleted all printers. How do I diagnose it further?

    can you open terminal and run:

    syslog |grep -i "Wake reason"

    and paste the full results here? I often have this exact same problem where something begins to prevent sleep, and usually the answer to what keeps the iMac awake is within these logs ^ usually it's a peripheral keeping the iMac awake erroneously, or some software I'm running doing something stupid.
