Hi Gaj
You really ought to post your own question. Bassel Kilo has not returned with more information in which a number of factors may have caused the problem. Without additional information no one is any closer to solving his complaint.
Among the reasons for posting a new question is that do not have the same hardware. As you wrote you "have a top of the line retina mac book pro" and the OP has a Mac Pro (as does Mr. Wills). We have no idea which of its eight models it may be, but none of them use the same graphics card as the Retina MBP.
Both you and he upgraded or updated from some as yet unknown version of OS X, no one knows which, but a Retina MBP may originally have had Lion or Mountain Lion installed. There are differences among those models as well.
As you can see the same complaint can arise from a number of different causes.
I think it is more helpful for the community to see that a set of users are all experiencing the same problem after updating to 10.8.3.
The symptoms may be the same, but if the hardware is different, the problems may not even be related, and no single solution can be proposed.
That is one reason the Terms of Use offers the following guidance:
Post constructive comments and questions. Unless otherwise noted, your Submission should either be a technical support question or a technical support answer.
I suggest that requesting more information is also appropriate when attempting to solve a problem. Pete asked, you didn't answer, and an argument is the predictable result. Were you two married at one time?
There are many examples of threads in which people tack on "me too" responses, but they do not conform to the above guidelines. I realize most people do not take the time to understand how this user support forum is supposed to work, but please understand that it helps no one to simply post "me too" when the combination of hardware and software and what people do with them together tends to produce unique problems. Joining the thread is a great idea if you can add to the information at hand, but doing so to simply draw attention to an issue will only hinder progress toward a solution.
I hope you reconsider your reticence to start a new thread, as well as others who posted "me too" replies. Doing that will accomplish exactly nothing.
