Apple has just opened its OS X Beta Seed Program to all Mac users. This means that all Mac users can have access to beta versions of the latest OS X releases, not only those who opted to pay $99/year.
According to Apple, “The OS X Beta See Program gives users the opportunity to run pre-release software, test drive beta software and provide quality and usability feedback that will make OS X even better.”
To join the OS X Beta Seed Program, all you have to do is sign up using your existing Apple ID, and accept the Beta Seed and Confidentiality Agreement. Apple will then give you a Beta Access Utility for your Mac. This will give you access to pre-release versions of OS X in the Mac App Store Update panel.
So, if you want to have first dib on the upcoming OS X 10.9.3 as well as iTunes 11.1.6, you might want to sign up for the OS X Beta Seed Program now. Of course, before you install any of the OS X releases available, its customary that you back up your machine and files. You can do this via Apple’s Time Machine utility.
