Apple Releases Firmware and OS X 10.8.5 Updates for Late-2013 iMacs
Apple has a released a new firmware update -- iMac SMC Firmware Update 1.1 -- for the new iMacs released in September.
Simultaneously, Apple also released a supplemental update for OS X 10.8.5.
iMac SMC Firmware Update 1.1
This update is recommended for iMac (late 2013) with flash-only storage. This update improves the Power Nap feature in 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.

This update:
- Fixes an issue that may cause external drives to be ejected after the computer goes to sleep
