Blizzard desktop app On March 23rd , 2017 , the app was renamed " Blizzard app " with version 1 . 8 . 0 . Although the Mac OS X version is still called just " Battle . net " . In mid - June 2013 , Blizz ard announced testing of the " Battle . net desktop app " and it was released as a Beta in mid - August 2013 . It appears to be a unified version of Blizzard Launcher for all of their games . It has a UI that resembles the more minimalist design of the Battle . net web site as compared with the more textured UI of the game - specific launcher . This replaces the launcher for all Blizzard games , and works similar to the older launchers , with background updates , repair tool , and more . On January 9 , 2018 , the Mac OS X version of the " Battle . net " app requested a restart and then failed to launch , instead going to the Blizzard Error app . Some of the problem may have been incompatibility with older OSes . Unexpectedly in mid - May 2017 , Blizz ard announced they would be hosting Bungie ' s Destiny 2 in the desktop app ( Windows - only ) . This is not the only Window - only app hosted , since Overwatch does not have a Mac version . Patch 1 . 7 was released in mid February 2017 and added a Suggested Friends feature that added several ways to look for potential new Battle . net friends ( friends of friends , Facebook friends , and Diablo friends ) . Patch 1 . 6 was released in late November , but apparently was wrongly versioned and patch 1 . 5 . 2 returned the next day . It was re - released on January 10 , 2017 . Patch 1 . 5 . 1 added Blizzard Voice Chat with Patch 1 . 5 . 2 adding improvements and bug fixes . Patch 1 . 5 of the desktop app supposedly added streaming capability via Facebook , but only in Windows OS . The Battle . net EULA ( End - User License Agreement ) was updated around August 1 , 2013 to go with this new app . It was updated again in February 26 , 2015 around the release of Patch 6 . 1 to take effect February 28 , 2015 . Around version 1 . 1 . 0 , the term " Beta " was removed from the app and related web pages , but Blizz ard never officially announced the Beta was ending or a release .

In patch 1 . 5 build 7963 , live streaming of video to Facebook capability was theoretically added the desktop app . The documentation for using this feature is rather poor as of Sep 7 , 2016 . Probably you will need to log in to Battle . net via Facebook , but it isn ' t clear . Blizzard Streaming only supports PCs running Windows Vista and up . 1 . 5 Voice chat ? In mid March 2016 , Blizz ard apparently released a closed Alpha of the Battle . net desktop app with Voice chat integrated . There was even an FAQ posted on the Battle . net forums that was acknowledged by blue poster s .

The open Beta was released Decmber 4 , 2013 .
