No date on patch, likely to be firmware-based
Apple has acknowledged the widespread keyboard and trackpad trouble reports with its new MacBook Pro models, unveiled last week. The problem manifests itself as a total freeze of input from either the trackpad or keyboard, and appears to affect every size and configuration of the laptop computer.
"Apple is aware of rare circumstances where the built-in keyboard and Multi-Touch trackpad may become unresponsive on 13-inch MacBook Pro with Retina display (Late 2013) computers and is working on an update to resolve this behavior," said Apple earlier today in a support Knowledgebase update. No timeline has been announced for the fix, which will likely manifest itself as a firmware update -- as OS X 10.9 Mavericks has been ruled out as a contributor to the problem.
Users discovered earlier this week that a hard reset fixes the problem immediately. Apple suggests closing the laptop lid for one minute or longer to force a reinitialization of the trackpad and keyboard following wake from sleep as a workaround.
