Apple posts entire WWDC 2015 keynote to YouTube

WWDC 2015 was filled with software product announcements, updates and more, including the debut of Apple's hotly anticipated Apple Music streaming service.

Following a humorous opening sketch starring SNL alum Bill Hader and a brief welcome message from Apple CEO Tim Cook, SVP of Software Engineering Craig Federighi took the stage to introduce OS X 10.11 El Capitan. When it launches this fall, the upcoming Mac operating system will come with user interface improvements and a number of backend enhancements targeting performance, deeper app integration and stability.

Apple also introduced iOS 9 with smarter Siri functionality and more inclusive high-level searches.

First party app features also got a shot in the arm. For example, Maps now sports Transit directions, while a new News app debuted and Passbook received a name change to Wallet. The Notes app will bring better Share Sheet integration with links, photo embeds and more.

Cook announced Apple Music as this year's "one more thing," revealing details about the upcoming service set to debut on June 30. The Beats Music-inspired product features access to an extensive iTunes-based catalog, human-curated playlists and radio stations, a 24/7 live radio channel called Beats 1 and Connect social networking. Pricing starts at $9.99 for single users and $14.99 for families with up to six members.
