Editing Kernel panic (section)

===macOS===
When a kernel panic occurs in [[macOS|Mac OS X]] 10.2 through 10.7, the computer displays a multilingual message informing the user that they need to reboot the system.<ref>{{cite web|url=http://support.apple.com/kb/TS3742|title=OS X: About kernel panics - Apple Support|website=support.apple.com|archive-date=May 21, 2013|archive-url=https://web.archive.org/web/20130521042317/http://support.apple.com/kb/TS3742|url-status=dead}}</ref> Prior to 10.2, a more traditional Unix-style panic message was displayed; in 10.8 and later, the computer automatically reboots and the message is only displayed as a skippable warning afterward. The format of the message varies from version to version:<ref>{{cite web|url=http://osxbook.com/book/bonus/chapter5/panic/|title=A New Screen of Death for Mac OS X|website=OSXBook.com|access-date=April 30, 2011|archive-date=May 1, 2012|archive-url=https://web.archive.org/web/20120501191934/http://osxbook.com/book/bonus/chapter5/panic/|url-status=dead}}</ref>

* 10.0&ndash;10.1: The system displays text on the screen, giving details about the error, and becomes unresponsive.
* 10.2: Rolls down a black transparent curtain then displays a message on a white background informing the user that they should restart the computer. The message is shown in [[English language|English]], [[French language|French]], [[German language|German]] and [[Japanese language|Japanese]].
* 10.3&ndash;10.5: Similar to 10.2, but the background of the error message is dark grey.
* 10.6&ndash;10.7: The text has been revised and now includes a [[Spanish language|Spanish]] translation.
* 10.8 and later: The computer becomes unresponsive before it immediately reboots. After restarting, it shows a message for a few seconds informing the user that a problem caused the computer to restart, before continuing to boot. The message now includes a [[Chinese language|Chinese]] translation.

If five new kernel panics occur within three minutes of the first one, the Mac will display a [[No symbol|prohibitory sign]] for thirty seconds, and then shut down; this is known as a "recurring kernel panic".<ref>{{cite web |title=OS X: About kernel panics |url=https://support.apple.com/en-us/TS3742 |url-status=dead |archive-url=https://web.archive.org/web/20180524032449/https://support.apple.com/en-us/TS3742 |archive-date=May 24, 2018 |website=Apple Support |publisher=Apple}}</ref>

In all versions above 10.2, the text is superimposed on a [[Power symbol|standby symbol]] and is not full screen. Debugging information is saved in [[Non-volatile random-access memory|NVRAM]] and written to a log file on reboot. In 10.7 there is a feature to automatically restart after a kernel panic. In some cases, on 10.2 and later, white text detailing the error may appear in addition to the standby symbol.
