Apple states on its support forum yesterday that it knows about the issue with some of its latest 13-inch Retina MacBook Pro. Actually in some new models of Apple's latest computers, the keyboard and multi-touch trackpad become unresponsive.
Apple clearly states that it is working on an update that will fix this issue. Apple states, "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."
In the mean time, Apple gives a solution of this issue. Apple asked affected customers to reset the unresponsive devices. Users have to just close their computer’s display for a minute and then open it to reset the unresponsive keyboard and trackpad.
