    Some users have noted that reinstalling macOS Sierra helped solve many problems that arose after the update. Therefore, it is absolutely not necessary to resort to extreme measures and perform a “clean” installation.

    Although there are many methods available for users to repair or reinstall their MAC OS X, in this article, we will keep our focus on reinstallation, which is done through Internet recovery mode. Critical data can be lost if the OS fails to recover, and to resolve this issue, it is important to learn about the process of reinstalling MAC OS X through Internet Recovery Mode. Although users are free to make their choice when it comes to choosing for a method, Internet Recovery Mode is certainly superior to many others, and in the next article, we should understand why.

    Part 1 When to go for Mac Internet recovery for MAC OS X

    We will answer the above question by classifying it into a series of questions, sub. Let's start with let's understand what Internet Mac recovery is.

    What is Mac Internet Recovery?

    Latest models Macs come with the functionality to run directly from the Internet version of Mac OS X recovery. This is especially useful in the case where you are faced with a problem starting the disk, or even worse, the OS is missing altogether. Erasing or wiping can happen accidentally or due to some software bugs and can lead to disruption to the user. Via the Internet Mac recovery users have the option to start their MAC directly through Apple servers. When users use this mode to start their systems, the system performs a fast storage space test along with checking hard drive for any other hardware errors.

    Why should you use Internet Recovery to Reinstall MAC?

    Well this is one of the most frequently asked question among those MAC operating systems. Why take all the hassle and choose to recover Internet instead of going in the usual way? In the following paragraphs we list the reasons that make re MAC installations via the Internet restoration of an intelligent option.

    • Disk operating system not needed to perform the reinstallation. This is useful in cases where you do not carry the OS disk and want to reinstall immediately to continue with your work.
    • No need for user to download separate files operating system. Internet Recovery Mode will download the installer files and as a user, you will get rid of the hassle of downloading them yourself.
    • This method is less complicated than the normal method of downloading and installing MAC OS X. It is useful for users who are not very interested in technical aspects installation process.


    What should you do before choosing Internet recovery?

    Here are the points that you need to keep in mind before you go to reinstall your MAC via Internet Recovery Mode:

    • For obvious reasons, you must have an Internet connection. Users should use their DHCP on WiFi or any Ethernet networks to install MAC OS X.
    • For those who purchased OS X from anyone Apple Store They may be prompted to enter the Apple ID or password that was used to purchase OS X.
    • Users should note that the time to reinstall OS X directly depends on the speed of the Internet connection being used. Please make sure your Internet settings are compatible with Mac OS X. If your settings are incompatible, the installation process may stop Midway.

    Part 2 How to Reinstall MAC OS X with Internet Recovery Mode

    Here are the steps that need to be taken. We start by accessing recovery mode on your MAC through the following steps:

    1) access recovery mode by holding down the Apple key and the R key.


    2) Users must ensure that they are connected to the Internet. We recommend using a private network for the same and avoiding any public network due to its configuration. Also installation file happens to be large, which can take quite a long time on any public network.


    3) now, turn off the MAC; Apple is shutting down. If the operating system is not responding, simply press and hold the power button while the MAC turns off and then wait 30 seconds.


    4) power on your Mac. Hold down the Apple key and R key until you hear a chiming noise. Once heard, it will start OS X in recovery mode.


    5) The last step is you clicking “Install MAC OS X” and continue to the OS X Utilities section of the screen in order to begin the installation process. After this, there will be on-screen instructions to guide you through the entire process.


    Part 3 What to do when Mac Internet Recovery Method Fails

    It is possible that you will not be able to reinstall your MAC OS X using Internet Recovery Mode successfully. While it may be the damper, that doesn't really mean you can't diagnose the problem behind it.

    Why can't there be an Internet recovery method?

    • Check that your Internet connection is working. Ethernet users should check for correct cable connections while WiFi users should check the modem.
    • If you are on a public network, there is a chance that the Internet settings may not be compatible with the installation process.
    • If the Internet is too slow, the process might abandon itself as the file to download is quite large.
    • Please check that your MAC is properly connected. In case of laptop computers, the battery should be sufficient. Losing power midway can render your device useless.

    Measures to take to ensure Internet Recovery Mode works:

    • As stated above, we recommend choosing private network Internet to carry out the above process. This is because large size installation file and the obstacles you want to avoid due to incompatible Internet settings and slow Internet.
    • Please make sure you have enough on your system. Losing power in the process can render the device useless.
    • If the problem persists even if the above two measures have been taken, there is a chance that your hard drive has been damaged completely and hence consult a technical advisor for the same.

    What if I lose important data in the process?

    For those who have lost important data in the process, it is possible to use Wondershare recovery Data for Mac It can be downloaded from the company's website and is useful for Windows and MAC users. We highlight his works in the following steps:

    With its own pre-installed operating system Mac system OS. Like all the company's products, it claims to be of exclusive quality and the use of advanced technologies. On at the moment The following varieties are available for sale:

    Find out how to update your Mac's OS in the article below.

    MacBook Pro is available in 13-inch and 15-inch sizes and in different specifications. All Mac models are equipped with Intel processors, battery life without recharging is up to 10 or up to 12 hours.

    The newest operating system currently used on Mac computers is Mac OS Sierra. Older versions of the OS can be updated for free via the Internet. The company's main advantage of the system is that it was created specifically for Mac equipment. Unlike Windows, which is installed on the most computers different manufacturers. By the way, now MacBook Pro and other models support the ability to install Windows.

    MacBook Pro and others are sold with the system already installed. However, in some cases, you may need to install or reinstall Mac OS on your MacBook. It is necessary to distinguish between the terms:

    • The installation is otherwise called a “clean” installation, which is performed on a blank (formatted) hard drive or on a new one.
    • Reinstallation is when a new system is installed over the old one without full formatting and saving user data.

    The need to install and reinstall Mac OS occurs when there are serious problems with its operation, failed 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. For previous versions, for example Mac OS X, there will be essentially no differences, but it is still recommended to update to the latest version if your device supports it.


    Operating system installation

    Clean installation may be required if you decide to sell your laptop and need to permanently delete 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. Creation bootable flash drive.
    3. System installation.

    To back up your data, use an external drive and Time Machine, which automatically launches when connected removable media. The utility will ask whether to use an external drive for backup, click “Use.” as a backup drive."


    After creation backup copy completed, you need to make a bootable USB flash drive using disk utility:

    The MacBook Pro itself will find the desired image on the flash drive and 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 - reinstall latest version OS installed on Mac, without updating to the latest.
    • Option+Command+R - update to the latest compatible Mac OS.
    • Shift+Option+Command+R - if your Mac already has macOS Sierra 10.12.4 or higher installed modern version, 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 you will install the system (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 a system with formatting the boot disk on your MacBook, not forgetting to copy all the data to external media, because after such a procedure they will all be deleted.

    Good afternoon, friends!
    I remind you that this post is for informational purposes only, we do not force, force or oblige you to perform these actions. Everything we do is for the sake of testing and then we delete it installed hackintosh. Well, you understand. So let's get started.

    The hardware on which we will install OS X 10.11 El Capitan:
    - Gigabyte GA-Z87m-HD3
    - Intel Core i3-4330 Haswell 2 cores at 3.5 GHz with Intel graphics HD 4600
    - 2 x 4 GB Samsung DDR-3 1600 MHz
    - 1 x SSD 120Gb SanDisk
    - 2 monitors (DVI + HDMI)

    This hardware runs almost everything out of the box, you only need a kext for the network and for sound, although the sound can be started by patching AppleHDA.kext. But that’s not what we’re talking about today, we’ll just install OS X 10.11 El Capitan on this hardware. This article is suitable for almost everyone, as it lays out the basics of creating a bootable USB flash drive with El Capitan.

    Preparing VMware
    The most big problem with the installation of OS X is associated with the lack of an original Mac, which, in principle, is not needed. Instead, we will use VMWare, on which we will run OS X El Capitan. From under virtual machine We will create our bootable USB flash drive.

    The action plan is:
    - download VMware Workstation 12.0.0 Build 2985596 Pro Final x64
    - download OS X 10.11.4 (Image for VMware)
    - download OS X 10.11 DMG (for installation)
    - download Unlocker for VMware 11+ (link below)
    - install VMware and run OS X 10.11 under it

    There is a problem with links, since the very popular torrent tracker *.org was blocked in Russia, so I will not give its address, but will only give some links from where you can download:
    - /forum/viewtopic.php?t=5069288 (VMware Workstation 12.0.0 Build 2985596 Pro Final x64)
    - /forum/viewtopic.php?t=5090705 (OS X El Capitan Image for VMware)
    - https://cloud.mail.ru/public/FQBt/6Ts8grepN - Install Unlocker for VMware after installing WMvare

    I think you already have an image of OS X 10.11, I won’t give specific links, since you can find it on the Internet yourself.

    Briefly, how to run OS X 10.11 from a virtual machine:

    1) Install VMware

    2) Download a special image from OS X 10.11

    3) Run VMware Unlocker as administrator

    4) Unzip OS X 10.11

    5) Launch VMware Player. Select our virtual machine image with OS X 10.11 and run it. If it complains about Hyper-V, do it using .

    It seems to me that you should not have any problems installing a virtual machine with OS X on board. Isn't that right? Well, great. In any case, your final installation result should look like this:

    I'll describe detailed creation bootable USB flash drive for OS X El Capitan using screenshots, so I think you won’t have any problems creating a flash drive. Everything is simple here. The only thing you need to do is turn on the display hidden files using the ShowHiddenFiles.app utility (link at the end of the article)

    If necessary, you can share the folder on Windows machine in VMware. To do this, press CTRL-D and do as in the screenshot:

    Creating a bootable USB flash drive with OS X El Capitan from Windows

    Open BaseSystem.dmg, which is located at Contents/SharedSupport/InstallESD.dmg (open image)/BaseSystem.dmg.
    You do not have to wait for the archive check; you can skip it.

    Format the flash drive

    To format the flash drive, open Disk Utility:

    Restoring the BaseSystem.dmg image to a flash drive

    We remove the shortcut to the Packages folder from our flash drive at OS X Base System/System/Installation and copy our folder to the place of the shortcut Packages from OS X Install ESD

    Don’t forget to put two files from the root of our flash drive OS X Install ESD, namely BaseSystem.chunklist and BaseSystem.dmg, otherwise the installation will not work:

    Download Clover from the official website (https://sourceforge.net/projects/cloverefiboot/) and install:

    We will not describe what Clover is. This is a bootloader that loads OS X on non-Apple hardware. Detailed information many on other sites, including official page project.

    Next, you need to put FakeSMC in the /EFI/Clover/kexts/10.11/ folder, and config.plist in the /EFI/Clover/ folder. The EFI folder is located on the desktop and appears after installing Clover. To mount it manually, you can use utilities such as Clover Configurator, which allows you to not only edit config.plist visually, but also mount the EFI folder.

    You need to create config.plist taking into account your hardware. I renamed GFX0 to IGPU, specified my Mac model and filled in ig-platform-id. For minimum installation this is enough, if you have different hardware, then you need the appropriate settings. If you don't have Intel graphics, you do not need to specify ig-platform-id.

    In this article I will not provide a description of the config.plist settings, I will try to do it another time, since I can’t remember everything from memory. I recommend that you read the book Clover in khaki. My config.plist can be downloaded at the end of the article.

    In addition, each hardware is individual and you need to select settings taking into account YOUR hardware. If your computer is similar to mine, try booting with my config.plist

    After recording the bootable USB flash drive, edit BIOS settings as shown below. These settings are suitable for motherboards Gigabyte Z87 series: GA-Z87-HD3, GA-Z87m-HD3 and others. Don't forget to enable UEFI boot only

    BIOS parameters for installing Hackintosh:

    Bios Features - VT-d = disabled (if selectable)
    Bios Features - limit CPUID Max = disabled
    Bios Features - Intel Virtualization Technology=enabled
    Bios Features - Secure Boot= disabled

    Peripherals - XHCI Mode = disabled
    Peripherals - XHCI Hand-off = enabled
    Peripherals - EHCI Hand-off = enabled
    Peripherals - Initial Display Output = IGFX (if you only have an integrated graphics card)
    Peripherals - Intel Processor Graphics = enabled
    Peripherals - Intel Processor Graphics Memory = 32 MB

    Performance - Extreme Memory Profile (X.M.P.) = Profile

    Press F12 and boot from the flash drive. If everything goes as it should, then in 20 minutes you will have El Capitan installed. Don't forget to install Clover again, but on your main hard drive, otherwise you will constantly have to boot from a flash drive!

    Required programs to install OS X 10.11 El Capitan:
    ShowHiddenFiles.app -
    PListEditor.app -
    config.plist - https://yadi.sk/d/eiFKPy2pdduSS
    FakeSMC.kext -

    After installing OS X 10.11 El Capitan, the system was removed from the computer.

    A public version of the new desktop operating system from Apple. Owners of Apple computers will be able to install the update for free from the application store. But before that, we recommend preparing your Mac for installing a new operating system.

    1. Compatibility check

    The first thing to do before installing any update or new version is software– check it system requirements. In short, El Capitan will run on all computers that could previously run OS X Yosemite.

    Full list of supported models:

    • iMac (Mid 2007 model or newer)
    • MacBook (late 2008 aluminum model, early 2009 model or newer)
    • MacBook Pro (Mid/Late 2007 model or newer)
    • MacBook Air (late 2008 model or newer)
    • Mac mini (early 2009 model or later)
    • Mac Pro (Early 2008 model or newer)
    • Xserve (early 2009 model)

    However, it is worth noting that some functions will only be available on new computer models from Apple.

    2. Installing updates

    3. Cleaning the hard drive

    Installing a new operating system can be a good reason to clean up your hard drive. unnecessary files and programs. You can put things in order both with your hands and with the help of special utilities. For example, such as CleanMyMac, DaisyDisk or MacBooster.

    4. Create a backup

    Before installing major updates, it is a good idea to back up the data stored on your hard drive. In case of problems, users will be able to quickly restore the functionality of the computer, while maintaining all important information. To create a backup, you can use a utility built into OS X called Time Machine.

    5. Checking the hard drive

    For owners of older models Mac computers Before installing a new system, you can also check your hard drive for errors. You can do this using Disk Utility.

    6. System installation

    It is worth noting that in the first hours after the release, the speed of downloading the system image from the application store will most likely be quite low. Therefore, we recommend waiting a little.

    The final version of the OS X El Capitan operating system for Mac. After testing the platform, we found out that Cupertino has seriously worked on the ergonomics and functionality of the OS: Mac users will find a number of interesting functions in OS X El Capitan.
