Black Screen After the Deathwing Patch
There have been reports of a black screen after the deathwing patch. Using Windowed mode will workaround the issue in the mean time.

  • CMD+M while in-game will force it into Windowed mode.
  • In the Blizzard App game settings menu (Options > Game Settings), check the Additional command line arguments and enter in: -DisplayMode=0

Black Screen after using CMD+TAB
This is currently a known issue. Using windowed mode will work around the issue in the mean time. In the Blizzard App game settings menu (Options > Game Settings), check the Additional command line arguments and enter in: -DisplayMode=0

If this does occur and the screen is black, restarting the mac isn’t necessary, press CMD+M to set it to windowed mode and bring the Heroes of the Storm client back.
