Posting to pre-empt the inevitable slew of posts asking it it's safe to install the beta on your ONLY Mac. The answer is always no and should always be no. There's always the risk to your data, incompatible apps, and not being able to roll back in case of problems.
Even with a backup, you might not be able to roll back, or it might hose your machine and then you will have to visit an Apple Store and if you depend on that Mac, then you will be in trouble.
Don't do it.
