Apple Releases Fix for 13-Inch Retina MacBook Pro Keyboard and Trackpad Issues
This update is recommended for MacBook Pro (Retina, 13-inch, late 2013) models.Users first began noticing issues that caused the keyboard and the trackpad of the 13-inch Retina MacBook Pro to freeze up shortly after the computer was released on October 22.
This update addresses an issue where the built-in keyboard and Multi-Touch trackpad may become unresponsive.
Multiple threads on Apple's Support Forums highlighted the issues and prompted Apple to notify users last week that it was working on a fix. While it was unclear whether the keyboard and trackpad unresponsiveness was due to a hardware or a software issue, it appears to be software-based and repairable with the EFI update.
The EFI update should be available through the Software Update tool in the Mac App Store for all users with an affected MacBook. Apple has also released an EFI update for the late 2013 15-inch Retina MacBook Pro.
