But you may encounter a type of system-wide crash that brings down your entire Mac: a kernel panic. When this occurs, there’s no warning and no way to save your work or do anything

else without restarting. And, because kernel panics can have many different causes, diagnosing the problem and preventing its recurrence are difficult. How do you know if it’s a kernel panic? If you’re running OS X 10.7 Lion or earlier, kernel panics usually result in your screen dimming from top to bottom, and a message appearing in several languages telling you that you must restart your Mac (by holding down the power button for several seconds to turn it off,

and then pressing it again to turn it back on). Up through Lion, a kernel panic looked like this (on an otherwise unresponsive screen). Starting in OS X 10.8 Mountain Lion, OS X automatically restarts when you have a kernel panic, and then displays a similar-looking message for 60 seconds (or until you press a key) telling you that your Mac was restarted because of a problem. (If the kernel panic repeats every time your Mac restarts, OS X will give up after five tries and shut your Mac down.) As Apple notes on its support page about kernel panics, something as random and fleeting as malformed network packets can potentially cause a kernel panic. So, if you experience this problem just once, or only rarely, just restart, get back to work, and forget about it. In Mountain Lion, OS X restarts automatically on a kernel panic and then lets you know what happened. But if you see a kernel panic frequently (Apple apparently defines “frequently” as “more than once every few weeks”), you should take additional troubleshooting steps. I suggest a slightly different sequence of steps than what Apple outlines. First things first If you’re running OS X 10.8 or later, immediately after your Mac restarts on its own you’ll see a dialog box asking whether you want to reopen the apps that were open before the crash. Click Open; if the

A kernel panic can also be caused by damaged or incompatible hardware, including external devices attached to your Mac. Important: To your computer restarted because of a problem mac el capitan print these instructions, click the Share button in the Help window, then choose Print. If the kernel panic is caused by a known problem, the faulty software is identified. To make sure that http://www.macworld.com/article/2027201/how-to-troubleshoot-a-kernel-panic.html this software doesn’t continue to cause kernel panics, move it to the Trash. If the faulty software is not identified and your Mac continues to experience kernel panics, try the following: Restart your Mac in safe mode. If it successfully starts up in safe mode, choose Apple menu > App Store, click Updates, then install any available updates. Uninstall any plug-ins or other enhancement software from manufacturers https://support.apple.com/kb/PH21900?viewlocale=en_CA&locale=en_CA other than Apple. If you recently updated OS X or an app, plug-ins and other software that worked in the past may no longer be compatible. Read the manufacturer’s documentation (including Read Me notes) to be sure the software is compatible with your version of OS X. Disconnect all USB and FireWire devices, except for the Apple keyboard and mouse. Remove hardware upgrades from other manufacturers, such as random–access memory (RAM) and Peripheral Component Interconnect cards. Then try restarting your Mac. If this resolves the issue, reconnect one device at a time, restarting your Mac after reconnecting each one, until you determine which device is causing the problem. Reset parameter random-access memory (PRAM). Use Apple Diagnostics or Apple Hardware Test. These apps can tell you if hardware you installed, such as additional memory, is incompatible, improperly installed, or defective.
If the steps above don’t help, try reinstalling OS X. Note: If you moved or renamed an OS X system file or folder, you must reinstall OS X. It won’t work to just replace or rename the specific item.

Kernel Panic (KP) is the equivalent of the Windows Blue Screen of Death for Unix-based operating systems, such as OS http://features.en.softonic.com/kernal-panic-mac-how-to-fix X and Linux. Technically, Kernel Panic is a kind of emergency procedure that the operating system https://www.youtube.com/watch?v=hegwkUEwDTk enables when it comes across a system error from which it cannot safely recover. Specifically, the OS will shut down automatically, and to use the computer again you’ll have to restart it manually. Kernel Panic is very rare, and isn't necessarily a symptom of a major problem. It can also be caused, for example, by a malfunction of a defective data kernel panic package. So, our first tip: if you only get one KP and, after the reboot, it doesn’t happen again (or at least it doesn't happen again for a long time) and everything seems to work normally, then you can relax and ignore what happened. If the Kernel Panic starts to become more frequent (for example, a couple every month), you should identify the problem and fix it. In this article, we'll tackle the problem from a software kernel panic mac point of view, but remember that sometimes the KP could have been caused by hardware. What can cause Kernel Panic? The most common cause is a hardware failure - either the Mac itself, or an external device or application. Some of these problems are only temporary and will disappear after a reboot, as we have already mentioned. Others are more complicated, and will stop you using your computer. Badly-written drivers or plugins could cause a KP or even the random presence of specific conditions. In these cases, the Mac should work properly again after the reboot. There are other, more complex problems that need to be identified and fixed. Let's start with the ones that are easier to spot. How to recognize Kernel Panic The easiest symptom to recognize is the classic screen with the start button image in the background, and the multilingual message that tells you: "You need to restart your computer." Sometimes, however, you don't get this default message, and your Mac could spontaneously restart, turn off, or stop responding to commands, forcing you to shut down the computer forcibly. In these cases, to be certain that it was a Kernel Panic, just go to /Library/Logs/DiagnosticReports (in Mavericks). There, if the problem was really a KP, you'll find a log with the details of the incident . Sometimes, however, this file could be missing, eve
