An EFI update available for both 13-inch and 15-inch Apple MacBook Pro with Retina, addressing the trackpad and keyboard problems.

Apple has finally solved the annoying bug occurred in new 13-inch MacBook Pro with Retina Display with upgrade to OS X Mavericks: Now the trackpad and keyboard are fully functional. Yesterday, the Cupertino developers released an EFI firmware update for both 13-inch and 15-inch MacBook Pro with Retina eliminating all errors.

A large number of consumers who have purchased a new 13-inch MacBook Pro with Retina Display suffered the malfunctioning — for some unspecified reason –of trackpad and keyboard after continuous use for few hours. To resolve this, it became necessary to close the laptop lid, so as to force the standby mode.

After a long series of complaints appeared on the official Apple support forum, a few days ago the group of Cupertino said that they were aware of the bug and would resolve the issues as soon as possible. So here are the EFI Update v1.2 and v1.3 for 13-inch and 15-inch MacBook Pro Retina, and these updates are also available via Software Update in the Mac App Store.

The cause of issues is yet unknown; however, the Appleā€™s support description reads:

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.
