Yes, it was a Late 2013 rMBP 256GB OS 10.9 and it did not have any usb plugged. I will go back again and maybe to another store to verify this is accurate information before I start to speculate. If you guys have an apple store nearby and if you can check the log of their display rMBP and look for this error I believe that would help to our discussion. So, if even the display rMBPs they have at the apple store are faulty then, I think, we could be more confident that this is in fact a software issue. Or a less probable, HUGE HUGE hardware issue.
The only reason I see this would be relevant, is to have enough information to make a good decision before the 15 days return policy. If I were Apple and this is a huge hardware issue, strategically, I would release that information after November 6th so cash flow is not affected, considering that there are a lot of people who have the problem but are either not aware of it or do not care enough (that minimizes the # of return computers). Again, I do not think this is the case, and I am holding to my rMBP until day 15 hoping it is a software issue but I just would like to have enough information by that date. The reason I am holding to my rMBP is because I have had many very reliable products from Apple in the past, this is my first issue in years, so I guess they still have my confidence.
As a side note, my brother is having a locked black screen issue with his 2012 13" MBP after installing Mavericks.
Again, thank you again for your great information and effort. I guess the good side of this problem is seeing so much collaboration among apple users.
