Patch 7 . 3 . 5 was announced at BlizzCon 2017 with its major feature being a modified version of level scaling coming to the PTR sometime before the end of 2017 . For a period of builds through early January 2018 , the Mac OS X version gave an error ( launched to Blizzard Error reporting app ) on attempt to launch starting with build 25607 and continuing through build 25717 and back in build 25753 through build 25807 . Build 25716 through 25744 failed to even find the Mac executable and couldn ' t even get the Blizzard Error .
