Apple has released a system management driver (SMC) update for MacBook Pro with Retina display. It made available the Power Nap function, a mode in which the MacBook can perform some tasks even in sleep mode. The update also fixes an issue with the computer waking up. The update is available via Software update in the main menu bar. Power Nap Apple two days ago, it also enabled MacBook Airs.
It's weird, but somehow the update doesn't want to reach me like this :-(
MacBook Pro Retina - MLion since 27.7.
