I've been playing Warcraft III on my MBP for a year. Yesterday my Warcraft III failed to open anymore and gave this error message: "Warcraft III was unable to initialize OpenGL. Please ensure you have OpenGL installed and that your display drivers are current." I haven't changed anything about my computer. The only problem I can think of is that I recently set Warcraft to use my external monitor instead of the MBP's in the game preferences. My external monitor is in a different city now, and Warcraft won't load.
