Big news today from Apple: the company is opening its OS X Beta Seed Program to its customers. In the past, you needed to be a developer to access beta builds of OS X, but as of OS X 10.9.3, released earlier today, customers can also apply for access.

“Join the OS X Beta Seed Program and help make OS X even better. Install the latest pre-release software, try it out, and submit your feedback,” reads Apple’s OS X Mavericks Beta page.

As a side note, you should always be careful when installing beta software. It’s beta because it’s still being tested, so don’t put it on any production machine.
