New Mac Pro 2013 and Resolve 11 crashing on export

I'm running Resolve 11 (software, not lite) on a 2013 12 core D700 Mac Pro (10.9.3) and every time I go to export it crashes. The rest of the app runs fine, but on export it makes it 80% through the first clip and goes from 100ish FPS to 0 and stays there. From this point on the entire machine runs like a snail, even after force quitting Resolve. I have access to a Mac Pro 3,1 and rMBP, so I can complete the project with Resolve 10, but the new group workflow looks to be a huge timesaver, and I might go ahead and upgrade the rMBP to Resolve 11 just in case it can export without issue. Does anybody have a clue of how quickly we can expect new builds on Resolve 11 during this beta or if the 10.9.4 beta is known to fix this?

Known issue with 10.9.3...literally a dozen threads on here about it.

Find/install a beta of 10.9.4 or wait for the release.

Some people have had success with the beta, others have not.
