Well, that complicates things. Due to the terms of the Apple beta software agreement, and those of the Apple Support Communities, we can provide no assistance for any Apple beta product. If you are a paying developer, then there is an exclusive support forum to be used for beta issues. If you are a public beta user, there is no support, but you are asked to give feedback using the designated methods.
