Kernel Panic is very rare, and isn't necessarily a symptom of https://support.apple.com/en-us/HT200553 a major problem. It can also be caused, for example, by a malfunction of a defective data 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 http://features.en.softonic.com/kernal-panic-mac-how-to-fix 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 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."

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 kernel panic 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 kernel panic mac 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, i
