Patch 7.2.5 hotfix2 build 24393 was released to the PTR released on June 22, 2017. Build 24414 and 24415 were released to Live on the same day, but skipping the PTR apparently. Blizzard acknowledged video problems on Mac OS X external displays, but nothing has been done so far. They also acknowledged a problem with loading screens on Intel GPU on Mac OS X.
