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.
