My mid 2012 iMac 27" with Mavericks sometimes won't sleep. Its screen is light up in the morning and I'm still logged in.

I am running Windows 8.1 in Parallels 9. But that's always running. So I doubt it's Windows fault. Is there anything I can do to analyze why it did not sleep?
Best Answer
backupd
is most of Time Machine. I think your computer is constantly backing up over a slowish network link such as WiFi.I suspect that you have a large amount of file changes every day. Is the Windows image you are running in in Parallels being backed up? That could do it? Go into
System Preferences
>Time Machine
and click onOptions...
This will allow you to exclude your image files from Time Machine.
If that doesn't work turn off
Time Machine
for a couple of days and see if the computer sleeps.
