Schmitz Apple has issued [1]MacBook Pro Retina SMC Update v1.1, which provides a fix for a 'rare issue' for slow frame rates while playing graphics-intensive games on the 15-inch model of the MacBook Pro with Retina display. The System Management Controller update also provides bug fixes for Power Nap and wake from sleep, as well as a fix for a fan control issue. While the latter isn't detailed in the release notes, it most likely addresses the overzealous fan spinning that's been discussed at great length on [2]Apple's support forums and noted at [3]Geek.com. After installing, the SMC will be updated to version 2.3f35.
