Alongside today's release of a firmware update addressing keyboard and trackpad issues on Apple's new 13-inch Retina MacBook Pro, the company has released a separate firmware update for owners of the new 15-inch models. The 15-inch Retina MacBook Pro update addresses a separate issue related to performance of the discrete NVIDIA graphics included on higher-end models.
This update is recommended for MacBook Pro (Retina, 15-inch, late 2013) models with NVIDIA graphics.
This update addresses an issue which, in rare cases, may limit the performance of the discrete graphics processor after a system wake or boot.
The firmware update, which is 5.22 MB in size, can be downloaded either directly from Apple's support site or through the Software Update mechanism in the Mac App Store for users on affected machines.
