Want to try the new Mac OS X beta? Lots of people do, but just because you have access to the files doesn’t mean it’s a good idea to install it on your machine. That’s why I recommend setting up a separate partition when giving things like this a try! It’s the safest way to try the Mac OS X beta software, without ever effecting your primary machine, and applications.
MAKE SURE YOU SET THIS UP MAC OS X EXTENDED (Journaled)
BETA OFFICIALLY RELEASED! Sign up for it here: appleseed.apple.com/sp/betaprogram/
I hope this tutorial helps you. Enjoy!
