Fixed with OS X 10.9 Mavericks
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
Update:
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.

Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.
This could potentially be caused by your graphics card. Be sure to check for updates for its driver.

I've tested the issue without any applications running, and the crash persists.
Regarding processor: I can't view the activity monitor during the crash because the display freezes. I mentioned that my fans don't rev up because it could be a sign that Minecraft was still trying to process the window expand...

I updated the Description to explain the F3+C affect on the window. It doesn't give me a crash report because it still freezes the display. The one time it unfroze from using the F3+C command, the minecraft window was black-screened...

The cards are up to date. I'm on a mac, so these updates are handled through the app store.
The crash report does not need to be created when it freezes; anytime will do. This will simply provide us with supplemental information about your computer system and software.
I used the text edit to stop the game from opening full screen but is THAT the solution. Are we not able to play Minecraft fullscreen? Please help. I play on a MAC OS X 1-.5.8 and I want to PLAY FULLSCREEN! What is the solution to stop the game from freezing when you try to play and it goes fullscreen???
This bug still occurs in the latest snapshot 13w41a, i tried expanding the minecraft window (when in windowed mode). My screen went black and then my macbook restarted.
After upgrading to OS X 10.9 Mavericks(update released today) this bug seems to be fixed for me, the window resizes as expected without restarting my computer as it did before the upgrade.

What applications are running when you do this?
Just to clarify, Minecraft sucks down processing power A LOT, even on more recent Macs.
Ran TextEdit on a Mac Pro 6 core. Same thing happened.
Try quitting everything and trying again.
