Can’t Launch Warcraft III in Fullscreen
This is currently a known issue that occurs in Fullscreen mode. This issue occurs in both Windows and Mac. Forcing Windowed mode is the workaround to launch the game. Here’s the steps to force windowed mode:

  1. Open your Battle.net application and select the Warcraft III tab
  2. Click the Options gear (above the news widget) and click Game Settings
  3. Scroll down to Warcraft III in the list and click the additional command line arguments box
  4. In the blank that pops up, add -windowmode windowed
  5. Click Done and retest the game

Here’s the main thread tracking the issue. If you are experiencing issues with launching the game in Windowed mode or it displays a black screen, please create your own thread or contact support.
