MacOS Kernel Panic History

A kernel panic is an equivalent of the black or blue screen of death for Mac OS X and macOS, which use a Unix-based kernel. The screen, translated in many different languages, simply tells the user that the Mac has restarted and is recovering from an error.

History[]

In early versions of Mac OS X, the details of the kernel panic were simply dumped to the screen in verbose mode.

Starting in Mac OS X 10.2 (Jaguar), the background was darkened as a message appeared in a light grey rectangle to inform the user that the computer needed to be restarted. In 10.3 to 10.7.5, the message shown in a dark gray background.

Starting in Mac OS X 10.8 (Mountain Lion), a kernel panic would cause the system to automatically restart and notify the user afterwards with a message on a gray background.

Starting in OS X 10.11 (El Capitan), the message after a kernel panic restart would be presented on a full black screen.
