Macbook pro won't turn on. MacBook won't boot (freezes on boot) - what to do. Fixing Errors Using Disk Utility

Question: Hello macbook air 13
I decided to clean the hard drive, since it was full through CMD + R

I cleaned it and as a result, when the computer is turned on, it gives out a blinking question mark. I decided to try to restore it through the disk street, but it did not work
I decided to restart the operating system, it did not work (after I click "continue" nothing happens)

In the end, I decided through the boot disk - it didn't work, it just isn't there

And I noticed that my Machition HD disk was missing (sort of called it)

Instead, I now have 2 disks
APPLE SSD SM0128G Media
Apple disk image media

None of them can be unmounted (the "connect" button does not work

What to do? For two days I have been tormented with a computer! Without it, as without hands ((

Answer: Good afternoon! There may be several problems: the OS partition has fallen off, you will need to restore / reinstall the operating system. Either there is a problem with the HDD / SSD drive (out / out of order), or the HDD cable. To begin with, in any case, you need to diagnose. To understand what the problem is and troubleshoot. After that, it will already be possible to name the problem, terms and amount of the repair. From a distance, unfortunately, without seeing the device, it is not possible to carry out diagnostics. You need an engineer to look at your device, in fact, in the SC. Bring it, we'll see. Diagnostics in our service center is free. Sincerely, MacPlus!

Question: Hello, tell me what can be done. I wanted to remove the pin code from the MacBook Air picked up and started to reboot the Windows system and it showed a black screen and it says there is no operating system? What to do?

Answer: Good afternoon! Perhaps the software of the device has flown. Reinstallation of the operating system is 1500r. You can also try to restore the software, we can say more accurately after the diagnosis. Device diagnostics are free.

Question: Good afternoon! I have a problem with a MacBook: when it is turned on normally, an apple appears on a gray background, a white background, and freezes on a blue background. At the same time, in safe mode, it starts, but it works poorly, freezes when I go to YouTube, for example. Before it stopped turning on, it sometimes hung, had to be turned off. What could be the problem? Help me please

Answer: Good afternoon! According to your description, there are many reasons, in order to figure it out exactly, it is necessary to carry out diagnostics, diagnostics are free on the day of contact. We will be happy to help

Question: Good day! You have useful and interesting articles and would like to contact you with diagnostics, but I do not live in Moscow. I want to ask this question. I have a MacBook about 13 mid 12, last year I changed my hard drive to seagate, although it is more smart (7200) than my native hitachi. It worked for me for 14 months and stopped loading. Thought he was dead and bought another hitachi. I put the old native hdd in place with it, the poppy worked fine, downloaded yosemite and connected a new disk via USB and installed the system. But stuck inside the poppy, he worked with glitches. And through yusb it worked fine. I gave this disc to the store and bought another siagate. The same problems, only inside the poppy it does not start at all, only yusb. Is the loop the problem? It's just strange that the old hdd works with this cable, and the others don't, although the disk that caused this problem was also bought in the store and worked fine

Answer: Good afternoon! Yes, most likely the matter is in the HDD cable or in the sata controller, there may also be a problem in the motherboard. We can say for sure only after the diagnosis, the diagnosis is free.

Let's not talk about Apple's reliability for the 100th time. Everything breaks down.

But this case is strange, almost paranormal - at least, it seems so when it happens to you.

Given: new MacBook in excellent condition and without repair. Sit, work behind him. Suddenly once - it turned off. Without warning, the screen went out and the power went out.

You try to turn it on, but it doesn't respond at all. No way. Long press the power button, connect the charging cable, change the charger. Just zero reaction.

Do not rush to go to the service just yet. And in general, do not rush. Perhaps this problem can be solved right now.

I faced Mac suddenly shutdown 2 times in 1 week

I believe in randomness, so I think I was just "lucky." But any of you can be in this place.

A week ago, a colleague of mine experienced the above issue on his MacBook Pro. The computer just turned off out of the blue and no longer showed any signs of life. I tried different charges, cables, open and close the lid. Useless.

A few days later, the situation repeated itself with me and the 12-inch MacBook. Only the circumstances are different.

I didn't have a sudden shutdown. The MacBook had 2% battery remaining when it went out. I didn't think anything bad, put it in my bag and forgot it. In the evening I put it on charge.

I open it in the morning, try to turn it on - zero reaction.

The laptop just seemed completely dead. It's a strange feeling - there was just a computer, and now a piece of metal with buttons. And it seems you are not to blame.

If you experience something like this, do not despair: most likely, the matter is a failure of the SMC controller.

What is an SMC controller, why is it needed?

Literally, SMC stands for System Management Controller, that is, system management controller.

This is a chip on the motherboard that performs several specific tasks. Quoting Apple's official website, SMC is responsible for:

• reaction to pressing the power button
• reaction to opening and closing the display lid on Mac laptops
• battery resource management
• temperature control
• sudden Motion Sensor (SMS)
• ambient light sensor operation
• keyboard backlight
• status indicator control
• battery status indicators
• select an external (instead of internal) video source for individual iMac displays.

SMC controllers are found on all Intel-based MacBooks. Under ideal operating conditions, they function without problems.

But for some, SMC may start to get stupid. The reason not to guess and not diagnose at home. These can be problems after an unsuccessful update or restoring the system from a backup, or power surges when recharging the battery. Or something else.

If the cause of the failure of the SMC is extremely difficult to determine, then you will notice the problems themselves almost immediately.

Again refer to the official Apple website for a list of situations requiring a reset of the SMC controller:

• The computer fans spin at high speeds, although the computer is not heavily loaded and ventilated properly.
• The keyboard backlight is not working properly.
• Status light (if present) is not lit properly.
• Battery lights (if present) do not work correctly on Mac notebook computers with a non-removable battery.
• The display backlight does not respond correctly to changes in ambient light.
• My Mac doesn't respond when I press the power button.
• The Mac notebook does not respond correctly to closing or opening the lid.
• Your Mac suddenly goes to sleep or shuts down and can't be turned on.
• The battery is not charging properly.
• Your MacBook or MacBook Pro won't charge through the built-in USB-C port.
• The MacBook or MacBook Pro does not recognize external devices connected to its built-in USB-C port.
• The MagSafe power adapter LED (if equipped) does not correctly display the current charging status.
• Your Mac is unusually slow despite not being overly CPU intensive.
• A Mac that supports Target Display Mode does not switch to Target Display Mode or back as expected, or switches unexpectedly.
• The lighting around the I / O ports on a Mac Pro (Late 2013) does not turn on when the computer is moved.

Okay, huh? Reading this list in its entirety makes you want to immediately reset the SMC settings on your Mac, no matter how it works. Suddenly it gets better.

Fortunately, the SMC reset procedure is safe, non-negative, and is often used by Apple service centers as a first step in resolving owner complaints. No data or settings will be lost. All files will be in place.

As you might guess, it was the SMC reset that helped me and a colleague to revive our MacBooks. Only the procedure was not as simple as described on the Apple website.

How do I reset SMC on my Mac?

If you have a MacBook with a non-removable battery: turn off your MacBook (if it is on), hold down the CMD (command) + Option (alt) + Shift keys on the left side of the keyboard, and the power button with your other hand. Keep it all pressed for 10 seconds, then release. Turn on your Mac as usual.

If your MacBook has a removable battery: throw it out, it's time to upgrade. Okay, seriously, you need to turn off the beech, remove the battery from it, hold down the power button for five seconds, then release it, insert the battery pack back and turn on the laptop normally.

If you have a desktop Mac, iMac, and Mac mini: turn it off, remove the power cable, wait 15 seconds. Insert the cable back. Wait another 5 seconds, turn it on as usual.

If you have an iMac Pro: turn off, hold the power button for 8 seconds, release it for 2 seconds and then just press.

Mac computers do not report that the SMC settings have actually been reset. If your problem persists, although it is mentioned in the reasons for resetting, try again. Once again.

Damn it, try ten times. Because for some unknown reason, it rarely happens the first time.

Personally, about the sixth attempt brought me success. The Mac suddenly turned on, started charging, and generally behaved as if nothing terrible had happened.

What if resetting the SMC didn't work and the Mac still won't turn on?

I highly recommend trying to reset the SMC at least five times. This observation is confirmed by numerous topics in Western forums. For some reason, the keyboard shortcut window is very small in newer MacBooks.

Apple appliances are famous not only for their ultra-trendy design, but also for their build quality. But, like any electronics, it can fail. And if the elimination of some breakdowns is the work of a specialist, then minor problems can be solved independently. So, what if the Macbook won't turn on.

Determine the cause of the malfunction

First of all, you need to inspect the laptop for visible damage. Special attention is needed devote to the power connector and charger - it should have a green indicator on when connected to the network. The connector itself, especially when using "non-native" charging, can be deformed or loosened. If you have an alternative charger, try turning on your Macbook using it.

One of the main reasons a Macbook may not turn on is a physical breakdown or a short circuit after being exposed to liquid. Even if the equipment did not fall or fell under the water with you, ask your relatives or colleagues. Perhaps they thought it was okay and didn't tell you. In this case, it is better not to try to turn on the poppy anymore (if possible, remove the battery), but go straight to the service center.

If there are no visible defects, and the Macbook does not turn on after recharging, perhaps the reason lies in the controller.

What "symptoms" should you immediately contact the service center?

• 1. If your Macbook stops turning on after being dropped, hit, or closed abruptly. In this case, any contact could come off or a crack could go along one of the boards. To establish the cause, it will be necessary to carry out diagnostics.
• 2. If the laptop has been spilled with liquid. In no case should you turn on the equipment if water, tea, juice or any other liquid gets into it - a short circuit may occur. The service center specialists will disassemble the Macbook, dry it, clean it and diagnose it. Repair may not be required.
• 3. If at the last start-up you hear a cotton or smell a specific smell. In this case, it could happen circuit board short... The exact cause can be determined only by resorting to diagnostics.

What you can try to do yourself

If you are sure that your Macbook has not crashed or flooded, you can still try turning it on.

• 1. Check if the charger is working properly... The indicator (green light) should light up when connected to the network and go out when disconnected.
• 2. Remove the battery (after disconnecting it from charging) and hold down the Power button for a couple of seconds. Reinsert the battery, connect the charger, and try turning on your Macbook again.
• 3. If the laptop is hot, wait until it cools down (this can take from half an hour to a couple of hours). Then try turning on your Macbook again. If the equipment works, you will need to clean it, for which contact the service center.

If none of the advice helped, it is better not to hesitate and contact a specialist. Remember that timely diagnostics and troubleshooting will help prevent more serious breakdowns, data loss and costly repairs. All of the above steps apply to both macbook Air and macbook pro.

Fair, not overpriced or understated. There should be prices on the Service website. Necessarily! without "asterisks", it is clear and detailed, where it is technically possible - the most accurate, final.

With the availability of spare parts, up to 85% of complex repairs can be completed in 1-2 days. Modular repairs take much less time. The website lists the approximate duration of any repair.

Warranty and liability

Any repairs must be guaranteed. Everything is described on the site and in the documents. The guarantee is self-confidence and respect for you. A 3-6 month warranty is good and sufficient. It is needed to check quality and hidden defects that cannot be detected immediately. You see honest and realistic terms (not 3 years), you can be sure that they will help you.

Half of the success in Apple repair is the quality and reliability of spare parts, so a good service works with suppliers directly, there are always several reliable channels and your own warehouse with proven spare parts for current models so that you do not have to waste time.

Free diagnostics

This is very important and has already become a good form for the service center. Diagnostics is the most difficult and important part of the repair, but you shouldn't pay a dime for it, even if you don't repair the device as a result.

Service repair and delivery

So that you have an idea of \u200b\u200bwhat exactly you need.
They will try to solve the problem. In most cases, the description tells you what happened and how to fix the problem.

Unfortunately, any computer user can face a problem when the operating system Mac won't boot and it seems to hang on the boot process. As a rule, it 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 not respond to anything other than a forced shutdown with the power button. 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 either. Why is this happening and how can it be dealt with? Is it required in such cases? Let's figure it out in order.

Why Mac won't boot and freeze at Apple logo

The reasons why the Mac has stopped booting can be various:

• Operating system failure associated with damage to important system files (for example, in the case of incorrect installation of updates to system components, or installation of a new OS).
• Damage to system files due to the action of malware.
• Lack of free space on the boot volume of the computer.
• Inability to determine the boot volume due to a software error or damage to the hard disk cable (an obvious symptom of this is).
• Defective hardware components (damaged hard disk or SSD, video chip defect, etc.).

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

Depending on the causes of 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 in the service center. Below are some guidelines for what you can do if your Mac stops booting and freezes at the Apple logo or loading indicator. Let's start simple.

Boot in Safe Mode

Few people know that the MacOS operating system allows you to boot into Safe mode, which allows you to identify various system software errors. Safe mode loads only the core of the system with the main important functions, while while booting the computer in safe mode, the file system is checked for errors and, if possible, eliminated. Therefore, in most mild cases, booting the Mac in Safe Mode followed by a correct soft restart can fix the problem if your Mac won't boot and freezes.

In order to boot your Mac (it doesn't matter whether it's MacBook, iMac or Mac Mini) in Safe Mode, you need when turning on the computer, hold down the "Shift" key on the keyboard and hold until the loading indicator bar appears. Note that the boot time for macOS in safe mode takes significantly longer than the standard boot of the operating system, so we recommend that you be patient.

Fixing Errors Using Disk Utility

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

To run the disk utility if the computer does not boot normally, you need to boot from the built-in MacOS recovery partition. This requires when turning on the computer, press the Alt / Option (⌥) button and hold it until the boot partition selection screen appears, then select the Recovery partition. Force boot from macOS recovery partition can be done by pressing keyboard shortcut Command (⌘) -R when the computer starts up.

When the recovery partition is launched, you must select the "Disk Utility" item:

In Disk Utility, select the "First Aid" section and click "Run" (valid for MacOS versions of 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 reports that the disk is healthy or repaired, try restarting your computer and check the operating system boot again. If the found errors are successfully corrected, MacOS should boot correctly in normal mode.

If, during the check, the disk utility displays an error message that cannot be fixed, 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 freezes at the loading indicator, and restoration by standard means does not work, 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.

In order to extract files from a boot volume that cannot be started, you will either need to connect the computer to another Mac in Target Disk Mode (the method is very difficult and requires a second Mac computer, a FireWire or Thunderbolth cable, and strict compliance with Mac OS versions on both computers), or connect to the computer from an external media with an installed operating system, or special software for extracting and transferring data.

Unfortunately, not every Mac user has the ability to carry out such manipulations and, faced with a situation where their computer stops loading correctly and freezes, and simple 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 for help. will be made as quickly as possible, taking into account all your wishes about saving important data and desired settings that our employees will make for your computer so that it will please with its stable work for a very long time.

I have just such a problem - Mac won't boot and freezes at the Apple logo
Hangs on an apple for a long time, then a chamomile appears, starts spinning and so on ad infinitum.
I have important data there and I am afraid of losing it. Can you restore me both the data and the performance of my MacBook?

• Hello Alexander!
  Sometimes, similar problems are associated with the physical dying of the hard drive on your macbook. Unfortunately, hard drives on MacBooks fail and not as infrequently as we would like. If you have such a situation, then we will need to separately remove the data that can be saved. After that, buy a new hard drive, install it, and return all the saved data back, having previously installed the system.
  The cost of such a service is agreed with the client, after a thorough diagnosis for hard disk damage.
