It refused to boot. CMD+R doesn't help. What should I do?

The start of the working day did not foretell anything bad. A cup of coffee, a good mood, the Power key and the MacBook displays the following sad picture:

A restless thought immediately flashed through my head about the safety of the data, the current version of the backup copy TimeMachine(which was not at hand) and possible loss of information.

Attempt No. 1. Booting into recovery mode

Being an interested user and an avid Mac user, I immediately tried to start the MacBook in recovery mode by holding down the keys CMD+R. Instead of the usual disk utility, the system greeted me with a window with an attempt network recovery.

Having chosen home Wi-Fi network, I began to wait for further developments. After a few minutes, OS X's recovery progress was interrupted error -4403F.

Attempts to start the process again led to exactly the same result. Rebooting the router confirmed that network connection everything is fine.

About the attempt to carry out Mac diagnostics, fixing possible hard drive errors or simply reinstalling the system was now out of the question. Section with Recovery HD, in which the tools for restoration are stored, ordered to live long.

Attempt No. 2. Resetting PRAM and NVRAM

Mac computers were created by highly qualified engineers, so the correct organization of the entire system and the presence of “hidden hardware reserves” allows you to avoid a number of interruptions in its operation. One of these reserves is memory sections PRAM And NVRAM. It stores settings data that is not reset even after the computer is disconnected from power. To revive the fallen system, a decision was made reset PRAM and NVRAM settings.

1. Turn on the Mac.
2. After the white screen appears, quickly press the key combination CMD + Option + P + R.
3. Hold until the Mac reboots again and the Mac greets the sound.

PRAM and NVRAM reset completed.

Although they say that hope dies last, it, lifeless and barely alive, continued to lurk in my mind. Resetting PRAM and NVRAM did not affect the error when loading the system. The MacBook continued to test my nerves.

Attempt No. 3. Reset SMS

Having become accustomed to storing all the necessary data “in the cloud” or on removable media, the simplest solution to global problems has always been to reinstall the system “from scratch.” This case was special. I needed data stored in memory and I needed a working Mac today.

In the Mac environment there is something called system management controller SMC. The stability of the entire system depends on the reliability of its operation. Resetting SMC settings can cure a number of problems like:

    – constantly high rotation speed of the cooler even at minimal load;
    – freezes while the system is leaving Sleep mode;
    – errors related to the operation of additional peripherals or external monitors, as well as correcting system boot problems.

To reset the SMC, follow these steps:

    Laptops with built-in batteries

1. Turn off your MacBook and plug in the power adapter.
2. Press and hold the keys at the same time Shit + Control + Option + Power and hold until the MagSafe adapter indicator changes color.
3. Release all keys and press the key again Power.

    Laptops with removable batteries (older models)

1. Turn off your MacBook and unplug the power adapter.
2. Remove the battery from the laptop.
3. Hold down the key Power And hold for at least 5 seconds.
4. Release Power, insert the battery and connect the power adapter. Turn on your laptop.

    Desktops (iMac, Mac mini, Mac Pro)

1. Completely disconnect the computer from the mains power.
2. Wait at least 30 seconds.
3. Connect the power and wait another 5-10 seconds and then turn on the computer.

The above actions can become really effective and the system will start. In my case, a miracle did not happen.

Attempt No. 4. Recovery using a bootable USB flash drive

An attempt to revive the system using the above actions was unsuccessful. The only option left was to reinstall OS X using a bootable USB flash drive. For this step you will need:

  • another computer running operating system OS X;
  • Flash drive with a size of at least 8 GB.

Preparing a flash drive

1. In the store Mac applications App Store You will need to download the OS X Yosemite system distribution.
2. To create a bootable USB flash drive, download the DiskMaker X utility (distributed for free). You will need it to deploy the distribution.
3. Format the flash drive using Disk Utility V Mac OS Extended (Journaled).

4. After the distribution has finished downloading, cancel the proposed installation and run the utility DiskMaker X.
5. Choose a system Yosemite (10.10). The utility will detect the distribution in the folder Applications. Click Use this copy(use this copy).

6. Select the drive installed in the USB port and agree to the warning about complete removal all data present on the flash drive.

7. The process of mounting the distribution kit with OS X Yosemite to the drive will begin.

The copying process takes about 10-20 minutes and depends on the writing speed of the USB flash drive. During mounting, dialog boxes and folders may occasionally open on the screen. Never mind.

Once the OS X Yosemite image has successfully deployed, remove the drive.

System installation
1. Insert the flash drive into the USB port of the “problem Mac”, press the key Power and hold down the key Alt.
2. In the list of available partitions for downloading, select OS X Base System. Please note that there is no section Recovery. .

3. The Mac will boot into recovery mode. After selecting the main system language, the installation menu will open. In the top menu you will find a standard list of utilities.

Use disk utility and first try to check the access rights to the system partition and correct any errors. If after rebooting the system still refuses to boot, you will need to separate a partition of at least 20 GB in size in order to install a new system. Detailed instructions by disk partitioning you will find .

From the same menu, you can either begin the process of installing the system on a newly created partition, or restore the system using a TimeMachine backup (see).

CAREFULLY! Be careful when choosing the installation partition. The installation must be carried out not on top of the old partition, but on a newly created one.

After installation is complete, you will have access to all data located on the “corrupted” partition with old version systems.

If you cannot create an additional disk partition

If for some reason you were unable to create an additional disk partition to install a new version of OS X, and saving the data remaining on the broken partition is still a priority, there is an option to install OS X using a previously created bootable USB flash drive on an external drive.

Reinstalling macOS (OS X) can be done for completely different reasons (selling a computer, solving software or hardware problems). In any case, this is a fairly simple (especially for Windows-based computers) process that does not require creating a bootable USB flash drive.

There are three main types of macOS reinstallation - with complete data clearing (if you, for example, sell your Mac), without deleting personal data, and restoring from a backup.

Attention!

  1. Both types of installation require an active Internet connection (the operating system is directly downloaded from Apple servers). If there is none, then you will need to create a bootable USB flash drive on another Mac or PC.
  2. If data safety is important to you, do not forget to do backup copy(if you have a second drive on your Mac or an external one hard drive use the utility Time Machine).

Reinstalling macOS (OS X) with full data formatting

Step 1 Start macOS in recovery mode by holding down the Command (⌘) + R or Option (⎇) + Command (⌘) + R keys when you turn on or restart your computer (if you cannot boot from the macOS recovery partition, then thanks to this keyboard shortcut you will launch macOS recovery over the Internet) until the Apple logo appears on the display

Step 2 Once the download is complete, the utilities window (macOS Utilities / OS X Utilities) will appear. Open Disk Utility and format the system hard drive


To do this:

  • select the volume or disk in the left side menu and click on the Erase button
  • Format select "Mac OS Extended (Journaled)"
  • enter a new volume or disk name
  • if you want to completely protect yourself and prevent further recovery of erased data by third parties, click “Security Options”, use the slider to specify the number of overwrite cycles over old data and click OK. Overwrite feature is not available for SSD drives
  • click Erase and Done

Step 3 From the utilities window, select Reinstall macOS or Reinstall OS X


Step 4 After downloading and installing macOS, the computer will restart and the setup assistant will launch. If the computer is for sale, then press the keyboard shortcut Command (⌘) + Q and select Shut down so that the new user can customize the Mac to their requirements

Reinstalling macOS (OS X) while maintaining personal data

Possible on Mac reinstalling mac OS to the current or older version of the operating system without deleting personal data. The entire process is almost identical to the previous chapter, except that you do not need to perform Step 2 (opt-out of Disk Utility and do not format the hard drive). After selecting the item Reinstall macOS or Reinstall OS X in Disk Utility, macOS will be reinstalled to the version that was last installed on the Mac.

Recovering macOS (OS X) via Time Machine

If you have a macOS backup created using the Time Machine utility, you can perform a system restore. During such a recovery, the hard drive is wiped and all its contents are replaced with data from the latest macOS and information from the Time Machine backup.

To restore macOS via Time Machine, follow these steps:

Step 1 Start macOS in recovery mode by holding down the Command (⌘) + R or Option (⎇) + Command (⌘) + R keys when you turn on or restart your computer (if booting from the macOS recovery partition fails, then thanks to this keyboard shortcut you will launch macOS recovery over the Internet) until the Apple logo appears on the display

Step 2 Once the download is complete, the utilities window (macOS Utilities / OS X Utilities) will appear. From the utilities window, select Restore from Time Machine backup and click Continue. Next, follow the instructions of the utility

The need to install and reinstall the Mac OS arises when there are serious problems with its operation or an unsuccessful update. Like Windows, it still leaves behind garbage, which over time leads to slowdowns, freezes and other troubles. We will consider these processes using the example of the latest operating system, namely Mac OS Sierra.

A clean installation may be necessary if you decide to sell your laptop and need to permanently remove all data and Apple ID from it, or if there is a serious system problem. The installation algorithm on a MakBook Pro looks like this:

  1. Data backup.
  2. Creating a bootable USB flash drive.
  3. System installation.

For backup data, use an external drive and the Time Machine program, which automatically launches when you connect a removable drive. The utility will ask whether to use an external drive for backup, click “Use.” as a backup drive."

After the backup is complete, you need to do bootable USB flash drive using disk utility:


MacBook Pro will find it itself the desired image on the flash drive and will begin installing the Mac operating system. You just need to follow the instructions on the screen.

Reinstalling the operating system

You can reinstall the system from the OS recovery menu on Mac OS, which is called up by a key combination during boot:

  • Command+R - reinstalls the latest version of the OS installed on the Mac, without updating to the latest.
  • Option+Command+R - update to the latest compatible Mac OS.
  • Shift+Option+Command+R - if macOS Sierra 10.12.4 or a newer version is already installed on your Mac, then pressing the combination will allow you to reinstall the OS that came with your Mac laptop.

After pressing these key combinations, a menu will appear in which you need to select “Reinstall Mac OS”. Next, do the following:

  1. When the name Mac OS Sierra is displayed, click Next.
  2. Select the drive on which the system will be installed (usually called Macintosh HD).
  3. The system reinstallation will begin, after which the Mac laptop will boot as usual.

All data, including passwords and Apple IDs, will be saved, as well as user data. But still create a backup copy before reinstalling, just in case. Reinstallation is also sometimes called recovery, since it often helps solve performance and performance problems. If the problems have not been corrected, then you can already try installing the system with formatting boot disk on your MacBook, not forgetting to copy all the data to an external drive, because after this procedure they will all be deleted.
