Constant Unity 4.6 crashes on OS X Mavericks

I am getting pretty consistent crashes of my Unity program when dealing with saving or switching scenes, primarily.

I upgraded to the 4.6 beta from 4.5 hoping this would help, but it did not.

The most common reason for Unity to crash seems to be me saving a scene, or double clicking on a scene in the project view. This happens in any project, including new ones and ones downloaded from the asset store. I also sometimes get crashes when I save the project, or attempt to build the project. There doesn't seem to be any data lost, only a crash after writing to the disc.

Bug reports have started hanging up on the zip phase and not sending, but I wanted to make sure my issue is known.

I repaired permissions on my hard drive, repaired my start up disc, tried external drives too.
