Why do many people prefer Mac when choosing a computer? The answer is obvious: it is reliability, safety, ease of use and high stability. The latest versions of macOS are so polished that users rarely encounter software bugs. However, if this still happened and the failure cannot be fixed by improvised means, you can perform a clean installation of macOS. Moreover, it is not at all difficult to do this.

Unlike Windows, the procedure for reinstalling macOS is as simple as possible. Without exaggeration, even an inexperienced user will cope with this task. All you need is a reliable internet connection and some of your personal time.

How to reinstall macOS

The first step is to connect the power adapter to your Mac. Next, you need to go into recovery mode and decide on the type of installation. There are three possible scenarios.

To enter Internet Recovery mode, immediately after turning on or restarting your Mac, you must hold one of the following key combinations until the globe logo appears:

After starting, you will need to wait a bit: if an Internet Recovery update is available, its latest version will be automatically downloaded.

If you did everything right, after a while the “Utilities” window will be displayed. If you want to get a clean operating system, it makes sense to completely format the drive in Disk Utility and specify the following options:

  • Disk name: the volume name can be anything. The default is Macintosh HD.
  • Format: to format the disk, use the APFS file system when installing High Sierra and newer, or Mac OS Extended (Journaled) for older versions.
  • Scheme: Select GUID Partition Scheme.

After cleaning the disk, you can proceed with the installation itself, of course, after specifying the desired drive. It is normal for your Mac to restart several times during the installation process. As a rule, the entire procedure takes no more than 30 minutes (provided that the installation is performed on a solid state drive).

If everything went well, we will be greeted by the "Setup Assistant" and we will be able to configure all the initial settings of the computer, as well as log into the Apple ID account. All is ready!

How often do you have to reinstall macOS? Let me know in the comments or

It refused to boot. cmd+r Does not help. How to be?

The beginning of the working day did not bode well. A cup of coffee, a good mood, the Power key and the MacBook displays the following dull picture:

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

Attempt #1. Boot in recovery mode

Being an inquisitive user and an avid "Makovod", I immediately tried to start the MacBook in recovery mode by holding the keys cmd+r. Instead of the usual disk utility, the system met me with a window with an attempt network recovery.

Having chosen my home Wi-Fi network, I began to wait for further developments. A few minutes later, OS X recovery progress was interrupted error -4403F.

Attempts to start the process again led to exactly the same result. Rebooting the router confirmed that everything was in order with the network connection.

Trying to diagnose a Mac, fix possible hard drive errors, or simply reinstall the system was now out of the question. Section with Recovery HD, which stores the tools for recovery, ordered to live a long time.

Attempt #2. Reset PRAM and NVRAM

Mac computers were built by high-class 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 are sections of memory PRAM and NVRAM. It stores settings data that is not reset even when the computer is turned off from the 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 hold down the key combination CMD+Option+P+R.
3. Hold until the next reboot and the Mac welcome sound.

PRAM and NVRAM reset is complete.

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

Attempt #3. Reset SMS

Accustomed to storing all the necessary data “in the cloud” or on removable media, the easiest solution to global problems has always been reinstalling the system from scratch. This case was special. I needed in-memory data, and I needed a working Mac today.

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

    – constantly high speed of rotation of the cooler even at minimal load;
    – freezes during system care in sleep mode;
    - errors related to the operation of additional peripherals or external monitors, as well as fixing 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. Simultaneously hold down the keys Shit + Control + Option + Power and hold until the MagSafe adapter light color changes.
3. Release all keys and press the key again power.

    Notebooks 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 unplug your computer from AC 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, the miracle did not happen.

Attempt #4. Recovery using a bootable flash drive

An attempt to revive the system using the above steps was unsuccessful. The only option left was to reinstall OS X using a bootable flash drive. This step will require:

  • another computer running the OS X operating system;
  • flash drive, at least 8 GB in size.

Preparing a flash drive

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

4. After the distribution is downloaded, cancel the proposed installation and run the utility Disk Maker X.
5. Choose a system Yosemite (10.10). The utility will detect the distribution kit in the folder Applications. Click Use this copy(use this copy).

6. Select the drive installed in the USB port and agree with the warning about the complete deletion of all data present on the USB flash drive.

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

The copying process takes about 10-20 minutes and depends on the write speed of the USB flash drive. During mounting, dialog boxes and folders may occasionally open on the screen. Do not pay attention.

After successfully deploying the OS X Yosemite image, remove the drive.

System installation
1. Insert a 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 download, select OS X Base System. Note the absence of a section Recovery. .

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

Use Disk Utility and try first to check the permissions on the system partition and fix any errors. If the system still refuses to boot after a reboot, you will need to separate a partition of at least 20 GB in order to install the new system. You will find detailed instructions for partitioning a disk.

From the same menu, it is possible to both start the process of installing the system on a newly created partition, and restore the system using a TimeMachine backup (see).

CAREFULLY! Be careful when choosing the installation partition. Installation is required to be carried out not over the old partition, but on the newly created one.

After the installation is completed, you will have access to all data located on the "corrupted" partition with the old version of the system.

If the creation of an additional disk partition failed

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 to an external drive.
