Reasons for freezing

All possible reasons Hanging can be divided into three main categories:

• program crash;
• OS crash;
• hardware failure.

Program crash

Apple technology is quite conservative. Despite this, some companies, as well as just private programmers, are developing software for MacBooks. Such crafts often cause equipment to freeze.

You can cope with this trouble in various ways:

• check everything installed programs for the presence of malware;
• use special quarantine;
• use Gatekeeper.

The best way to deal with a problem is to prevent it from occurring. That is why the technology from the manufacturer in question has a function to check programs for the presence of malware.

If there is even the slightest probability of something like this being present on the PC, a corresponding message will immediately be displayed on the computer screen. Also this function allows you to quarantine an application.

The Gatekeeper feature, which is implemented in OSX Lion 10.75, makes it possible for their developers to attach special signatures to programs. Installing software that does not have special digital signature, is simply impossible. Gatekeeper is blocking it. Using this function makes it possible to prevent possible freezes.

OS crash

Often various types of problems arise due to failure of the operating room MacBook systems. Moreover, this is only possible if certain actions are taken by the attackers.

This failure occurs as a result of a deliberate DoS attack - a denial of service occurs. To do this, the attacker needs to send just one network package to his victim. This is possible in Apple OS X and iOS.

Today we will look at various options for turning on or rebooting.

How to turn off a MacBook if it's frozen

If the MacBook freezes and refuses to turn off, then usually the cursor remains working. This usually happens when one application freezes and prevents the entire MacBook from functioning properly. The first thing to do is press the keyboard shortcut Command + Q. What if you don't know it, but this combination completely terminates the process of the application that is open in at the moment. Note, it doesn’t just hide, it covers. We recommend waiting at least a minute before ending the application.

There is a chance that the application is simply trying to perform your last action. In this case, the MacBook cursor should look like a spinning rainbow icon. If in the usual ways It was not possible to terminate the application and it does not turn on, then you need to use the “Force Quit” command. This team is located in top menu With Apple logo. From the window that appears, select the application that does not load or turn on, and then click the “End” button.

Emergency shutdown

If the MacBook is frozen, as they say, “tightly”, then you can use forced shutdown. You should resort to this method only if the MacBook refuses to respond at all to your cursor movements or key combinations, that is, it is completely frozen. This is also worth doing if your MacBook displays a white screen. “Hard restart” is an unpleasant procedure for the MacBook itself, because it is stressful for it - all applications are abruptly terminated. But if the computer freezes, then there is no choice.

To do this, press the power button power macbook and hold it until the screen goes off. This usually takes 10 seconds. The main rule is to be patient, if the computer is seriously frozen, the shutdown may last longer than 10 seconds. Therefore, do not be nervous, just wait and, most importantly, leave your finger on the button until the screen goes dark.

White screen

Most unpleasant problem– this is a white screen on a laptop that is frozen and will not start. If the MacBook starts up and the cooler spins, but the white screen still remains, then most likely the computer does not boot due to:

1. The communication cable between the video card and the display has come loose or is completely broken. Try removing the cable and connecting it again. Very often the cable fails, resulting in a white screen. More often than not, such a malfunction can be solved in one way - by replacing the cable.
2. There is also a possibility that the MacBook does not start, and the white screen refuses to disappear due to a faulty matrix. Unfortunately, the screen is the most fragile part of the computer, so it is quite difficult to find out about problems with it. It is also unlikely that it will be possible to carry out a replacement at home.

Laptop won't turn on

You need to understand that when a laptop does not turn on or does not boot, the solution to the problem most likely lies in the hardware. It's rare that a laptop won't boot or start due to software. The problem with the white display will most likely be solved only in service center. All you can do is check if the monitor cable is in place or hard drive. Yes, also this problem can occur due to external media, which is incorrectly connected to your laptop. To do this, disconnect all external devices and check if it starts.

If your device does not even turn on, then the problem may be in the battery - try connecting the MacBook to the network, that is, so that it works from a power outlet, and not from offline mode. If it still does not boot, you need to look for a solution exclusively at the Apple repair center, they will explain why the computer froze.
