Technical literacy

If you ask a question, a specialist should answer it as accurately as possible.
So that you can imagine what exactly you need.
They will try to solve the problem. In most cases, from the description you can understand what happened and how to fix the problem.

What to do if suddenly screen doesn't work MacBook laptop Air, Pro? Of course, in this case it will be impossible to continue working. First of all, we advise you to connect the laptop to the monitor and check if an image appears on the external monitor. If it appears, then the problem lies in your laptop, or more precisely, either in the cable or in the matrix itself. If it does not show, as a rule, the problem is hidden in the hardware. Let's consider possible options more details.

1. First of all, check if problems occur when opening or closing the laptop lid. Often, when closed, the MacBook simply turns off or goes into sleep mode. When opened, the screen turns on again. As a rule, the reason lies in the mechanical power button itself, which suffers the most and becomes unusable due to dirt. In this case, it just sticks. Users can simply fill it with liquid, causing it to simply short out. The button is located in the most visible place. As a rule, in the upper right corner, on the panel where the display is, or at the end. If there is a malfunction, the power button will need to be replaced. This simple task takes very little time.
2. If the monitor shows, but there is no backlight, this basically means that the inverter or the backlight itself is damaged. It is these components that are responsible for the display backlight. If the inverter is not badly damaged, it can be repaired by otherwise- it is replaced with a new one. The backlight lamp cannot be repaired, only replacing it completely will help.
3. If the matrix is ​​black, and there is backlighting on the sides or not, then the problem lies in the hardware itself.

Take a closer look at the possible options:

When the MacBook Air, Pro laptop display does not turn on

If your MacBook laptop boots up and everything freezes.

1. This primarily happens through problems with the hard drive.
2. It is possible that an error occurred on the hard drive.

A laptop computer can also freeze after receiving mechanical damage or as a result of moisture getting inside.

The specialists of our Telemama service center are always ready to lend a helping hand. We will repair it qualitatively MacBook Air,MacBook Pro.

Apple computers are highly reliable, but their owners sometimes run into trouble. Let's figure out what needs to be done when the MacBook does not turn on. If you didn’t manage to flood your laptop and didn’t drop it on the floor, the problem can most likely be solved without going to a service center.

First, you should perform an external test to ensure that the monitor and power adapter are working properly. The first applies more to the owners Mac Mini and all-in-one iMacs. Laptops manufactured before 2016 use a MagSafe magnetic port for charging. Its power cord is equipped with an indicator light.

At correct connection it should glow orange or green. The L-shaped magnetic latch can operate even if the contacts have not yet connected. In this case, the power cord is externally connected, but due to slight misalignment, power is not supplied. The latest generation of T-latches do not have this drawback. Make sure MagSafe is connected correctly.

All 12-inch models, and after 2016 – the MacBook Pro, use a power supply with a USB-C connector, which does not have a light indication. MagSafe remains only in Air. The cord of the new adapters has two identical connectors at the ends and connects to the laptop and power supply through a port.

Unplug it on both sides and plug it back in. The adapter can automatically interrupt the power supply if there is a disturbance in the electrical network. To reset the triggered protection, unplug it from the socket for one minute. Once turned back on, the computer should begin charging normally.

Reset NVRAM/PRAM

When the adapter is working properly, power is supplied and the apple on the lid is lit, but the screen is still black, you will need to reset the NVRAM/PRAM.

1. Completely turn off the computer using the power button. Turn it on and immediately press the combination shown in the screenshot.

1. We hold down all the keys until the laptop starts up, making beep download again. After the startup went smoothly and we are logged in, we need to check for updates. Click on the apple logo in the menu bar located in the left corner. Select the marked item.

1. On home page Click the indicated button to open the App Store.

The system will automatically check for updates. We install all available ones and, if necessary, update the OS to latest version High Sierra.

Resetting the SMC

The SMC controller is responsible for the power supply functions. These include battery management, response to closing and opening the lid, the operation of some system sensors and interaction with peripheral devices. In any case, if you feel like your Mac isn't working properly, forcefully restarting the controller may resolve the issues.

For Aimak monoblocks and all Mini versions Simply unplug the power cord for 15 seconds. You must wait at least five more seconds before turning it back on. For laptop computers, which includes all versions of Air, Pro and 12-inch Retina, we perform the following steps.

1. Turn off the device completely using the menu item shown.

1. Disconnect the power cord. Press the three keys shown in the screenshot in the left corner simultaneously with the power button and hold for ten seconds. Reconnect the power adapter and turn on the laptop.

As in the previous case, we check and install available OS updates.

Consequences of the upgrade

Apple has made it almost impossible to upgrade in recent years. In previously released MacBooks, the user could independently replace the memory sticks. The operation is, in principle, simple, but requires the correct selection of modules. If, after an upgrade, the laptop starts beeping while turning it on, this indicates problems with the new memory.

In this case, signals are given with a pause of five seconds. Depending on the model, this may be one repeating beep or a series of three consecutive beeps. The only way out of this situation is to reinstall old modules or purchase suitable ones.

In conclusion

If resetting the NVRAM and SMC didn't help you, then your Mac has serious problems. The best solution You will need to contact a certified service for professional diagnostics. Don't forget that your MacBook will have limited access for a year from the date of activation. Apple warranty and some repairs can be performed free of charge.

Video instructions

In the video below you can see firsthand how the described operations are performed by a professional.

Many of you have probably heard that Apple's operating system is famous for its reliability and the low number of errors and failures that occur during operation. However, Mac OS, unfortunately, is not perfect and one day it may simply not boot for no reason at all.

Without a doubt, this behavior of your Mac can be caused by a number of different errors, which need to be eliminated in different ways, but the author of this article in lately increasingly faced with a situation where MacBook won't boot after latest update operating system (Mac OS Sierra in this particular case) and makes three loud squeaks, repeated with a certain frequency.

Unfortunately, this can happen to any of us, and contacting a service center is often not timely and, of course, not cheap. Luckily, there's an easy method worth trying before you take your Mac anywhere. Judging by the reviews on foreign forums, it helped many people save money on using the service, and such a “hint” has helped the author of this article more than once. This is what we will talk about. So, what to do if your MacBook won't turn on?

Error appearing when booting Mac

As mentioned above, a computer can behave in a similar way due to a number of different errors (at least 4, judging by the help on the Apple website).

However, in our case, the sequence of actions and the patient’s symptoms look like this:

1. you have installed an update to the Mac OS operating system (or the computer installed it itself if you have auto-update enabled);
2. when you turned on (rebooted) your MacBook, instead of the expected operating system loading bar, you saw only a black (well, slightly gray, the side backlight of the monitor still turns on) screen;
3. Looking at this “light black” screen, you heard three long sounds like “beep-beep-beep”, repeated at intervals of 5 seconds.

Having carefully studied the official Apple website, we find the symptoms and description of our error:

"Three consecutive beeps, repeated with a five-second pause: RAM has failed the data integrity check."

Okay, I see, it's a RAM error on our MacBook. But the officials somehow forgot to offer any solution. But we found it, and it turned out to be as simple as shelling pears. Of course, it’s not a fact that this method will help you 100%, but it’s worth a try, because... for many it is works.

By the way, judging by discussions on foreign forums, the following MacBook models most often produce this error and do not turn on: MacBook Air a1466, MacBook Pro a1278 and a1260. It is from the first that we are writing this article.

Solving the problem - resetting SMC parameters

So if your MacBook Air, MacBook Pro, iMac, Mac mini or Mac Pro won't turn on and beeps- This indicates a random access memory (RAM) error, which can most often be resolved by resetting the System Management Controller (SMC).

Depending on what device you have, follow one of the algorithms below.

If you have a MacBook with a non-removable battery

And most modern models are like this, then the algorithm of actions for you is as follows:

If you have a MacBook with a removable battery

Although, in my opinion, these have not been produced for a long time, but just in case, we proceed as follows:

If you have an iMac, Mac mini, or Mac Pro

That is, one of desktop computers from Apple, then resetting the System Management Controller (SMC) settings is even easier:

Using the method appropriate for your Mac, you will most likely see the usual Mac OS loading window - this means that the problem is solved.

What does resetting SMC affect?

If you are not very knowledgeable about computers or are simply encountering such a procedure for the first time, then before performing the steps described above, a completely reasonable question may arise: “Will I lose important data or settings on my MacBook as a result of resetting, because this procedure is somewhat similar to "hard reset" on some gadgets?"

We hasten to reassure you - no, you will not lose anything important. If you are really interested, then take a look at the list of functions for which the system management controller (SMC) is responsible, the parameters of which we reset:

• response to pressing the power button;
• response to opening and closing the display lid on Mac laptops;
• battery resource management;
• temperature control;
• sudden motion sensor;
• ambient light sensor;
• keyboard backlight;
• status indicator control;
• battery status indicators;
• Select an external (rather than internal) video source for select iMac displays.

Alternative option - rearrange the RAM

If the above option didn’t help and your MacBook still won’t start, then it’s worth a try alternative way. However, it is not suitable for everyone Mac computer, but only for those whose RAM can be replaced, and not soldered to motherboard(as is done in most modern Mac models).

If you have one of these computers, then this option may well help you, you just need to know how to get to the slot RAM. The algorithm of actions is very simple:

That's it. Now you know what you can try first if your Mac won’t start and beeps with a nasty signal. We hope that one of the options suggested above will help you solve this problem and save a significant amount of money on contacting a service center.

Unfortunately, any computer user may encounter a problem when the operating system Mac won't boot and seems to freeze during the loading process. It usually looks like this: the computer starts to boot, the Apple logo appears on the screen as usual, but then nothing happens - the system does not boot, and the computer does nothing but forced shutdown The power button does not respond. In other cases, a loading indicator may appear under the Apple logo (similar to the one shown in the image above), but then nothing happens. Why does this happen and how can you fight it? Is it required in such cases? Let's figure it out in order.

Why Mac won't boot and freezes at the Apple logo

The reasons why the Mac stopped booting can be different:

• Operating system failure due to damage to important system files(for example, in case of incorrect installation of a system component update, or installation of a new OS).
• Damage to system files due to malware.
• Absence free space on the computer's boot volume.
• Inability to detect the boot volume due to a software error or cable damage hard drive(a clear symptom of this is).
• Malfunction of hardware components (damage to the hard drive or SSD, defective video chip, etc.).

Mac won't boot and freezes. What to do?

Depending on the reasons for the problem, there are different variations of its solution. Some you can try to implement yourself, while others can only be implemented by a specialist at a service center. Below we will give some recommendations on what you can do if your Mac stops booting and is stuck at the Apple logo or loading indicator. Let's start with something simple.

Boot in Safe Mode

Few people know that the MacOS operating system allows you to boot into safe mode(Safe mode), which allows you to identify various software errors in the system. IN Safe mode mode, only the system kernel with the main important functions is loaded, and when the computer boots in safe mode, the file system is checked for errors and, if possible, eliminated. Therefore, in most mild cases Mac boot in safe mode followed by a correct soft reboot can solve the problem if your Mac won't boot and freezes.

In order to boot your Mac (it doesn't matter whether it's a MacBook, iMac or Mac Mini) in safe mode, you need to When you turn on the computer, hold down the "Shift" key on the keyboard and hold until the loading indicator bar appears. Please note that macOS boot time in safe mode takes significantly longer than a standard operating system boot, so we recommend being patient.

Correcting Errors Using Disk Utility

Disk Utility is a specialized application for working with the boot volume and file system MacOS, which allows, in addition to standard features formatting or partitioning the disk, check the disk and boot partition for errors and correct access rights to system files.

To run Disk Utility if your computer won't boot normally, you need to boot from the built-in MacOS recovery partition. For this it is necessary When you turn on the computer, press the Alt/Option (⌥) button and hold it until the boot partition selection screen appears, then select the Recovery partition. Force booting from MacOS recovery partition can be done by pressing a keyboard shortcut Command (⌘)-R when you start the computer.

When the recovery partition is launched, you need to select "Disk Utility":

In Disk Utility, select the "First Aid" section and click "Run" (relevant for MacOS versions El Capitan and Sierra), or manually select "Check Disk" and "Check Permissions" (available for OS X Yosemite and older). If at the end of the process disk utility will report that the disk is good or restored, then try restarting the computer and check the loading of the operating system again. In case of successful correction of the found MacOS errors should boot correctly in normal mode.

If, during the scanning process, the disk utility displays an error message that cannot be corrected, you should think about how to save important files and documents, and then reinstall the operating system.

Reinstalling the MacOS operating system

If the Mac does not boot and hangs on the loading indicator, and restoring using standard means does not produce results, then, most likely, it will hardly be possible to do without reinstalling the operating system. At the same time, given the fact that the computer does not boot, retrieving the user’s files and documents can be very problematic.

To extract files from a boot volume that can't start, you'll either need to connect your computer to another Mac in external drive(the method is not very simple and requires a second Mac computer, a FireWire or Thunderbolth cable, as well as strict compliance with the Mac OS versions on both computers), or connect to a computer with external media with an installed operating system, or a special software to extract and transfer data.

Unfortunately, not every Mac user has the opportunity to carry out such manipulations and, faced with a situation where their computer stops loading correctly and freezes, and simple ways solutions to the problem do not help, they simply do not know what to do. If your MacBook Pro, MacBook Air or iMac does not boot or the operating system freezes when loading, you can always contact our service center specialists for help. will be carried out as quickly as possible, taking into account all your wishes about saving important data and the desired settings that our employees will make for your computer, so that it will delight you with its stable operation for a very long time.

I have exactly the same problem - my Mac won't boot and freezes at the Apple logo
It hangs on the apple for a long time, then a chamomile appears, starts spinning, and so on ad infinitum.
I have important data there and I'm afraid of losing it. Can you restore both the data and the functionality of my MacBook?

• Hello Alexander!
  Sometimes, such problems are associated with the physical death of the hard drive on your Macbook. Unfortunately, hard drives on MacBooks fail, and not as rarely as we would like. If this is your situation, then we will need to separately remove the data that can be saved. After that buy a new one hard drive, install it, and return all saved data back, after installing the system.
  The cost of such a service is agreed upon with the client, after a thorough diagnosis of hard drive damage.
