In an unusual move, Apple has decided to open OS X Mavericks beta program to everyone. Until now the beta program was reserved to developers only.

If you are interested in testing the next builds of OS X Mavericks you can sign up .

Testing software is not for everyone, so before installing any beta version make sure to understand that:

• Beta means unfinished. By definition software in beta is buggy and should not be run in a production system. You might lose data, don’t blame Apple for that!
• Don’t start writing app developers that their application doesn’t work with the beta of the operating system you are testing. Those developers cannot update their apps until a final version of the operating system is made public.
