Apple has just made the beta tests of OS X updates available to the public at large. If you're feeling adventurous and/or want early access to bug fixes and new features, this is for you.


Note, if you decide to join this and get early access to updates, make sure you have a really good backup. This is not only pre-release software but it's pre-release system software so if something goes wrong, it might very well go horribly wrong. Take Apple's advice when you join the program about backups.
