I have met the same problem too!

Mine is also the new macbook pro Haswell.





I have been using my macbook for 2 days.

And I have encountered sudden freeze for 4 times!





The keyboard and the trackpad are unresponsive.

But actually the system is working and the apps are working.





And the power button can actually work.

So every time I met this problem,I long press the power button and make it restart.

And then everything is okay.





Somtimes ,if you wait for 10~15 min, the keyboard and the trackpad will start working again.

When the second time I met this problem, I decided to go to the apple store for help.

But after several mins, it works again.





It is very annoying that the system suddenly freeze when you are busy working on the documents.

And it causes damage that you force to shut down the macbook.





I think it is a software problem?

Hope Apple can release some updates to solve this problem soon!
