Previously, you needed a developer account to help test future softwareApple before they are accessible to the general public. It wasn’t really about developing anything, but it still cost you $ 99 a year to participate. Today, Apple has presented its OS X Beta Seed program to test the Mac operating system to anyone who wants it.
You can register at this address, with just an iTunes account. Once registered, users can test beta versions of Mavericks software before it is available to everyone, and provide feedback to Apple to help fix the issues before the general launch.
The program is available with its own special user software for installation on your Mac, making pre-versions of Mac OS X visible in the Updates tab of your Mac App Store. Those who like to test new technologies before they hit the market will appreciate the opportunity.
