With Yosemite (OS X 10.10) and the OS X Beta Program, Apple is for the first time since 2000 making pre-release versions of a new operating system available to people other than developers. Specifically, the first million non-developers to sign up for the 10.10 public beta will get to download and install pre-release versions of Yosemite, with the goal being to help Apple find and fix bugs before the OS is officially released.
