Please note that since pre-release software or beta software has not yet been commercially-released by Apple, it may contain errors or inaccuracies and may not function as well as commercially-released software. Be sure to back up your computer using Time Machine before installing this pre-release software and install it only on non-production or machines that are not business critical.
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.
The first public build of Yosemite is the same one received by registered Mac developers earlier this week. Developers who are testing Yosemite are on a different track than regular users, however, and both groups may receive different updates at different times as testing continues.
Apple developers know to use the company’s Radar bug tracker to file bugs, but regular users won’t need to. Instead, Apple will ask users to send feedback and communicate bugs via the Feedback Assistant app, which will be installed along with Yosemite on all beta-test systems.
Update (2014-07-26): Dan Frakes:
As with previous versions of OS X, it’s not difficult to create a bootable installer drive from the Yosemite beta installer, though the processes have changed slightly since Mavericks. I show you how, below.
It’s neat to get a first glimpse at a new operating system. But most users don’t really need this, so think carefully whether you do. If you decide to install it, make sure to do it safely.
Sorry, you’re wrong. Your app may be compatible with the latest beta of Yosemite, but claiming that it’s compatible with Yosemite is misleading. Until the GM – the golden master, the final release version – is released, no one can be sure that their apps are compatible with an operating system.
