Following its media event in San Francisco, Apple also released a slew of final betas for its three leading operating systems: iOS 9, OS X 10.11 El Capitan, and watchOS 2. The iOS 9 "golden master," which will be identical to the released code unless major bugs are found, also includes the first developer beta of iOS 9.1. In addition, Apple has notified developers that they may obtain the revamped Apple TV units in advance of the general public for testing the new tvOS and features of the device.
