I have a 15" MBP (mid (2010) with an SSD.  I bought the MAcWorl book "Total Mountain Lion Superguide", and it says to enable Power Nap on some older MBP require a firmware upgrade.  It gives no clue WHAT firmware and how old a computer.  I don't have the option to enable it so I'm assuming I need the upgrade.  Anyone know what that might be?

    Only MacBookAirs and Retina MacBookPros have the necessary hardware to utilize PowerNap.  It requires an integrated flash-based SSD.

    The book is incorrect then.  The only models that support Power Nap are certain models of MacBook Air and the new MacBook Pro with Retina Display.  And some of those models required a firmware update, which would show up in Software Update if it were supported on your model.

     

    Are you sure the book doesn't say that certain older MacBook Airs require the firmware update?  Because that would be correct.  But no MacBook Pro with a DVD supports Power Nap.

    Hmm, aren't all SSDs Flash based?  The book specifically say's "older laptops" so obviously pre-Retina.

    Your SSD is flash-based, but it isn't integrated into the systemboard.  It still requires a separate power supply (same as any standard SATA interface).

     

    The flash memory in the Airs and Retina Pros is integrated into the system board and does not require power to operate, which is what allows it to work while the computer is otherwise in sleep mode.

    The Firmware update is the SMC 1.5 update and only applies to the earlier versions of supported MBA and some rMBPs (likely the ones sold prior to the Lion 10.7.4 update).  Basically, it came up when a user went to Update Software, and then it only came up if it applied.

     

    This is the applicable firmware update: http://support.apple.com/kb/HT5394

    that is very well explained. now i know why my MBP mid 2010 is not compatible with powernap inspite of having an SSD.
