Curtain of death
iMac12,2 - 3.4 GHz, Intel Core i7 - Randomly and without warning, a black transparent curtain descends from the top of the screen to the bottom and all input devices are blocked. A message in five languages appears in the middle of the screen. The message says "You need to restart your computer. Hold down the power button until the machine turns off then push the power button to restart." This has occurred ~10 time since purchasing the machine about a month ago. The events are logged, this is the last one:
