Macbook pro retina display sudden shutdown

Question

So I've been using my new macbook pro with retina display for about a week now, and its shutdown several times on its own.  The computer just goes black, and then turns on with a grey screen that says it had to shutdown and is restarting.  Anyone else had this happen?

Answer 1

Unfortunately, the Retina is simply full of bugs.  There was very little testing of this unit, and only a handful of apps (mostly Apple) were ready for this most amazing display.  Apple was caught up (again) in it's own world of secrecy and marketing, therefore WE the users end up doing their testing for them.  I'm sure Apple Engineering was furious they couldn't even QA the best laptop design to ever hit the planet.
There are dozens of posts now surfacing on the web regarding HI issues (Human Interface) and video drivers.  It'll be months before 3rd parties are ready, and that's only if they were lucky enough to receive an eval unit.  It'll be just as long for Apple to fix the Retina's internal problems like chip updates and drivers. In the meantime, expect app cores, kernel panics, crashes and overall unusability and a general un-trustworthiness.
Your choice, like everyone else having issues, is to wait it out and hope there's no serious hardware changes needed for fixes, or just return it and wait for everyone else to plow through the issues.  Of course if you do that, you won't have [partial] use of the best laptop ever - until it's fixed. 
In any event, Apple held shipping of further units for at least 6 weeks to deal with this mess, so maybe the 2cd round will be a little more stable. Remember, some people aren't having any problems at all.  Some will.  Some have.
