    I have a new 21.5" iMac. I noticed there was an option for Power Nap. What is the advantage to using it, or leaving it off? Is it really necessary to check for email or have Time Machine do backups if you're not even using it?

    In the middle of several books.
    It doesn't hurt to leave Powernap off. The energy saved by having it on will be negligible. I have never turned mine on.

    Power Nap simply just lets it all be ready for you when you wake your Mac up from sleep. Software updates installed, Time Machine done backing up the big movie you edited before you put it to sleep. It's just convenience.
