wird schon nicht so schlimm werden. Das Beta-Programm ist auf 1 Million Teilnehmer weltweit limitiert…

mal sehen, wie viele aus diesem Forum es geschafft haben, sich zu registrieren.

Ausserdem sollten die Teilnehmer das "Kleingedruckte" lesen, die Software steht trotz public beta status unter NDA.
Aus den FAQ:

Is the pre-release software I am installing confidential?
Yes, the pre-release software is Apple confidential information. For example, don’t install the pre-release Apple software on any systems you don't directly control or that you share with others, don’t blog, post screen shots, tweet or publicly post information about the pre-release Apple software, and don't discuss the pre-release Apple software with or demonstrate it to others who are not in the OS X Beta Program. For clarity, if Apple has publicly disclosed technical information about the pre-release software then it is no longer considered confidential.
