You posted in the forum for the public beta, your Fusion version 6.0.4 tells me you are using the release version.
One of the features of the public beta ( VMware Fusion Technology Preview 2014 [ARCHIVED] ) is:
Improved support for unreleased versions of Mac OS X (new)
I can't promise you that it helps, but you might want to give it a try.
PS: If you'd prefer staying with Fusion 6.0.4 then that's fine too and I'll move your post to the correct forum.
