Kernel panic restart

A message at startup showing that a kernel panic has occurred and OS X has restarted.

A kernel panic is like a Black or Blue Screen of Death for Mac OS X, which uses a UNIX-based kernel. The screen, translated in many different languages, simply tells the user that the computer has restarted and is recovering from an error.


Before Mac OS X 10.2, the details of the kernel panic were simply dumped to the screen.

You need to restart your computer

Self explanatory kernel panic message in OS X 10.7.

In Mac OS X 10.2, a white message shows up that informs you need to restart your computer. This design lasted for several iterations of OS X, and in OS X versions between 10.3 and 10.7, the message shown is not full-screen and is on a black background.
