Kernel crashes on Mac: why they come out and what is the solution

Macs are not perfect computers, and like any other technological product they can have different flaws. One of the most annoying is the kernel bug that completely blocks the computer and makes it impossible to use it on many occasions. In this article we tell you everything you need to know about this failure and the ways you can easily solve it.

How are these types of failures

Kernel crashes on Mac

Kernel faults can be defined in a simple way to a procedure that completely stops the operating system when something is not working properly. That is, if the operating system when booting or while it is running detects a critical failure, it stops as it is impossible for it to function properly. This is why it is formally called a kernel panic failure. It is important to note that we are talking about something that is not very common and that you will rarely see on your computer screen.

In some cases it can occur as a result of a process that has been looped. That is why in most cases you will simply have to restart the Mac so that everything works correctly again. Although, it can also cause these failures to be repeated every so often, preventing the operating system from being used correctly. That is why this is where you should try to analyze the problem and the possible causes it has.

The way to identify it

Knowing if your Mac is experiencing a kernel bug is really easy. It is always characterized by the appearance of a completely black screen with the on or off icon in the background . On this icon you can read a text in several languages in which it is reported that the computer needs to restart due to an error. It is clearly informed how you will have to perform the restart by holding down the start button.

Likewise, there are also other ways for this kernel failure to occur that are more rare. One of them is the constant restart of the computer or the inability to recognize the different commands that you enter. All this is indicative that the operating system is detecting failures and cannot function properly, having to review the different causes of this failure.

What to check on your Mac

Once you know what a kernel bug is and how it can be detected while using your Mac, it’s time to finally figure out how to fix it. There are several causes that can occur when this failure occurs and the solution is to always tackle them at the root.

Check the applications you run

One of the most common failures that can occur is related to applications. When one of these is not well written or has been executed incorrectly, it can generate an error that is interpreted by the operating system as an impediment to function correctly. Without a doubt, it is easy to know which application is causing this failure since simply when you restart the Mac due to an error, the option to open the same applications will appear.

In this case it is important to open them so that the Mac is exactly as before and wait. If a kernel crash occurs again, it is quite likely that these applications are to blame for the problem. Now you will simply have to open each of the apps individually and wait for the error to be given. If just one of the open apps gives the kernel error, you must proceed to uninstall it and in this way the failure will be resolved with enough security.

Many applications start on startup?

Among all the applications that you have installed and running, a special mention must be made of those that start automatically when you start the computer. It must be taken into account that an overload in this sense may not be supported by the operating system and also in many cases the presence of a virus causes a strange app to always run at the beginning without your knowledge.

In these cases, you should deactivate those applications that you do not normally use and that are suspicious. To do this, you simply have to follow the system path Configuration> Users> Start and uncheck all the boxes for unnecessary apps. It is also important to start in safe mode if it is impossible for you to reach this part of the configuration. In this way, they will all be deactivated natively and you can easily deactivate them.

Drivers may be the problem

In the case that you have bought a printer or any other accessory relatively recently, you will have had to install a specific driver. It should be noted that this software is not Windows specific as you might imagine. In this case, the drivers are programs that are installed so that these accessories work correctly.

Although in many cases these drivers are not completely compatible with the version of software you have on Mac. That is why a review of the latest drivers that you have installed should be carried out to see if they are compatible. The accessory in question may also be to blame when you access its functionalities, in these cases it is recommended to disconnect it completely and check if there is a kernel failure.

Keep the hard drive clean

When the computer starts up, what it does is read the information that the hard disk contains, which is where the operating system is stored. It is important that it is in good condition and always with free space to be able to start. When the operating system starts, different temporary files are created and that is why there must always be a free space. If this is not the case, not all software files will be able to run. That is why it is always recommended to have the storage unit as orderly as possible and without any type of junk or useless file.

A system can be found natively to be able to diagnose the failures that exist in the storage unit. To do this, you simply have to access Disk Utility through the browser. Select the main storage unit where you have the operating system and at the top click on ‘first help’. At the moment a diagnosis of the unit will be executed so that you can be aware of the presence of a critical failure.

Ways to radically fix it

It may be the case in which these solutions that we have raised previously do not work. In these situations you should always go on to try to solve it with methods that are much more “extreme” such as reinstalling the operating system and also go to technical service. We will explain them to you in detail below.

Reinstall macOS

One of the most radical solutions to kernel failure is reinstalling the entire operating system. As we have mentioned on several occasions, this is a bug that is related to the software. That is why as a last option you can delete all the files that exist on the computer and go through installing macOS again.

It is important to bear in mind that when the operating system is installed again it must always be done from scratch. By this we mean that it should not be reinstalled through a backup. If it is done with a Time Machine backup it can finally cause all the problems that cause the kernel failure to be extrapolated with this reinstallation and the formatting that has been done has not been used at all.

Go to Apple

The last solution that arises before this problem is to go to the technical service so that the corresponding diagnosis of what is happening is carried out. Keep in mind that another cause of kernel failure is the presence of a hardware error. Although we are talking about a mainly software problem, it must be borne in mind that both hardware and software go hand in hand on Mac.

In this way, if a part such as the motherboard does not work or if the chip is defective, it can end up causing this kernel failure. In the SAT they will be able to give you all the necessary information of what is happening, being the most common that the motherboard is burned due to a variation in the voltage. This diagnosis can be made by making an appointment at the Apple Store or any authorized store. Although if you do not have any option at hand in your location you can request the collection of the equipment at home and receive it after a few days completely repaired and working without this failure.
