mavericks_round_iconApple today seeded build 13D17 of OS X 10.9.3 to developers, one week after releasing the first OS X 10.9.3 beta, build 13D12. The beta is available through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.

Apple is currently asking developers to focus on Graphics Drivers and Audio. As was discovered last week, 10.9.3 adds new support for 4K displays, offering "Retina" resolutions that improve readability along with support for 60Hz output from the Retina MacBook Pro.

You might take note that MacRumors actually has useful information in it.

Do NDA's mean nothing anymore. Seriously if you are part of the program and you post here you are in violation of your NDA.

There is no other mechanism available to me to get support.

The seed discussion area is broken.
I can't take the machine to the genius bar because it's running a seed.
I can't run the feedback assistant because the machine is bricked.

WTF else can I do?!

If Apple wants to get mad at me for posting here, then that's fine with me. They've seriously screwed the pooch and I have no other options.

The beta also includes a 4K display option for 60Ghz output from the Retina MacBook Pro.

60Ghz huh? That's pretty good. ;)

Not to rebut everything you said above but you are incorrect. I will not disclose which points. I am not trying to be rude or pick a fight you are just not correct. With that being said. Go into recovery mode and if you are part of the seed the new seed will automatically download, the recovery partition I am sure is intact.
So far as I am aware, there is no newer seed. It would download the same one, which I have no particular reason to believe will resolve the WindowServer's assertion failure.

Your assertion that I am incorrect with no supporting evidence has no more value than simply saying "neener neener."

I think your "Name," says it all.

My username is first initial, last name. It's been that for 30 years.

The reason I can't rebut your specific issues is the fact I won't violate any agreement I am currently under. Every negative assertion is clearly in conflict with what I know to be true. So take what you posted and each individual assertion reverse it and boom, there you have it.

You could have been helpful, but you've been so much more.

At the time I posted there was nothing else here about it.

So information I provided was useful.

I didn't know how long it would take for a news story to go up here about it.

Who cares? MacRumors actually provided people with relevant information.
