      When Minecraft is running with a singleplayer or multiplayer world loaded, pressing the expand button on a mac in the top left corner of the Minecraft window typically:

      • Freezes up all activity on the screen (except the ability to move around the mouse)
      • Causes the minecraft window to change to various randomly placed text and odd visuals of black squares and random images
      • Background audio continues to play from other applications but not Minecraft
      • The fans don't rev up on the macbook so it isn't burdening the processor
      • If you wait long enough, the computer will catch up with a few processes but won't completely work at proper speed until you manage to quit minecraft by spamming the force quit hotkey


      • Freeze occurs even on lowest graphic settings, and tiny render distance.
      • Freeze occurs even if the minecraft window is already at the maximum screening dimensions (Filling your screen) and you hit the expand button (intending for it to get smaller), it still crashes and random images are displayed in the window.
      • Holding F3+C for 10 seconds, after the expand bug has locked up the display, will cause: the minecraft window to change to a new set of odd visuals, very slightly decrease or increase the window dimensions (based on whether you were increasing/decreasing with the expand button), and changes your mouse to the rainbow spinning wheel.
      • In one instance, when the screen was already at max dimensions for my screen, I hit the expand button (as to make the window smaller) and as usual it froze. However, holding F3+C for 10 seconds and letting it sit for 30 seconds successfully made the window minimize to the proper dimensions yet was completely black. I could use other applications and everything seemed fine, however, as long as the black screened minecraft was still open, the mac top bar wouldn't say it was switching between applications, it only said 'Minecraft' in the top left of the screen, even though I could use menu items for other applications that simply appeared to open behind the 'Minecraft' menu item. Force-quitting the blackscreened minecraft window made everything normal again.
      • Crash also occurs when dragging the corner of the Minecraft window as to expand it.

      To prevent starting Minecraft fullscreen and thus crashing:
      - Quit Minecraft
      - Locate Minecraft folder http://hopper.minecraft.net/help/finding-minecraft-data-folder/
      - Open the file options.txt with a text editor,
      - Change the line fullscreen:true to fullscreen:false
      - Save the file
      - Start Minecraft
