iMac SMC Firmware Update is recommended for iMac (late 2013) with flash-only storage. This update improves the Power Nap feature in OS X 10.9 Mavericks on your flash-based iMac by allowing it to perform silently, without spinning up the fan.

Power Nap periodically updates apps, such as Mail, Contacts, and Calendar, and will download software updates while your iMac is sleeping.

Requirements

  • OS X 10.8.2 or later
  • iMac (late 2013) with flash-only storage

I never know if I should install these or not. Is this for all Intel iMacs or just those who care about Bootcamp?

Taken from: http://docs.info.apple.com/article.html?artnum=303725%94

"The SMC Firmware Update 1.0 is a System Management Control (SMC) firmware update for certain Intel-based computers, including iMac (Early 2006), Mac mini (Early 2006) and MacBook Pro (15-inch) computers..."

So it looks like the update effects the "behind the scenes" management of the machines. Perhaps affecting thermal/power management? I would be very interested in the results users have after this update.

Anyway, I think you should keep you Mac up-to-date with the lastest firmware (what Apple recommends). It can't (shouldn't?) hurt your Mac.
