Installing mac sierra. Installing macOS Sierra on PC. What to do after installing macOS Sierra

Sooner or later the day comes when you need to reinstall the Mac OS operating system on your MacBook PC. This task- no more difficult than reinstalling Windows. This is what we will talk about.

operating system on MacBook

Reasons for reinstallation operating system MacOS on a Mac computer are:

  • Damage or wear of the built-in storage device (HDD);
  • selling or donating a MacBook to another person;
  • "moving" to another MacBook (more new model, but with preservation previous version Mac systems OS);
  • data transfer to Apple gadgets or to another computer.

What happens when reinstalling MacOS:

  • “from scratch”, including formatting the built-in disk;
  • reinstallation “on top”, preserving personal data and applications (macOS update).

For example, using the MacAppStore you can update the version of OS X Lion and OS X Mountain Lion to the newer OS X Mavericks.

Here are the steps to follow when selling or transferring your Mac to someone else. It deserves special mention.

  1. Backup personal data from a MacBook to a separate media or cloud service.
  2. Shutdown special services and functionality that controls copying and transferring data.
  3. Erase all personal information from disk.

Attention! Before you start reinstalling MacOS on your MacBook PC, take the trouble to save all your data on external media! This will be discussed first.

Backing up your data using Time Machine

The Time Machine application is designed to backup personal files from a MacBook and restore them back to it. But it requires external USB drives (HDD, SDD drives) formatted in MacOS Extended or Xsan - file systems FAT/NTFS designed for Windows and Android are not supported. If the disk was previously formatted in FAT/NTFS formats, the MacBook will not accept it if you refuse to reformat it “for yourself.”

The Time Machine application is launched from system settings MacOS in apple menu. When connecting an external hard drive a corresponding notification will appear.

Do you really want to destroy all data recorded on this drive in a different format?

If the external drive has already been formatted, the Time Machine application will give the go-ahead for its use. Confirm your request.

Do you really want to copy your data to this drive?

If Time Machine does not show disk selection, do the following.


Interestingly, backups in the Time Machine program are fully automated - the backup copy is “refreshed” hourly, and their storage is organized, so you won’t get lost in them. In addition, copying is also possible to Apple server(like iCloud) and in storage local network, supporting Apple File Protocol. All this often helps, if you need to reinstall MacOS, to avoid losing precious working time.

After copying all your data, you can start reinstalling MacOS.

Reinstalling MacOS on Mac

There are several ways to reinstall the MacOS operating system on a MacBook: “clean” installation from a flash drive, installation “over” the previous version (updating from MacAppStore) and MacOS recovery from a backup.

How to reinstall Mac OS from an installation flash drive

The preliminary steps are as follows.

  1. Download installation image Mac OS X operating system from the store Mac App Store or from third party sites.
  2. When downloading is complete, click right click mouse over the downloaded file and select “Show package contents”.
  3. Go to the /Contents/SharedSupport/ folder, copy the InstallESD.dmg file to safe place on the disk and mount it on your MacOS desktop.

We will need the application " Disk Utility", included with MacOS. Next steps are like that.


Disk Utility will create an installation flash drive in automatic mode, and she performs this operation quite reliably. When copying is complete, Disk Utility will notify you.

Congratulations! Installation flash drive MacOS is created! You can restart your MacBook. Preparing to install MacOS is as follows.


All! MacOS installation has started. The MacOS operating system will install automatically - this will take 30-100 minutes, depending on the performance of your MacBook. After it, your PC will be immediately ready for use.

How to install the system without formatting the internal drive

Installing MacOS without erasing the disk means downloading and installing MacOS updates directly from the MacAppStore. An installation flash drive is not needed here. This reminds iOS update on smartphones and tablets over the air. This method is good for those who once bought a MacBook - and are not going to change it, but, on the contrary, will work on it for many years, because MacBook computers, like Apple iDevice gadgets, are very high quality, reliable and convenient.

Before updating, check whether your MacBook meets the hardware requirements of the new version of MacOS - otherwise it will slow down.

Not every previous version of MacOS can be updated to the desired version. So, if your MacBook is running macOS Snow Leopard (10.6.8) and your MacBook will run macOS Sierra, first upgrade to macOS X El Capitan.

The version of MacOS Sierra is taken as an example. Other copies are searched for and “installed” in exactly the same way. Your actions are as follows.


If you have OS X El Capitan 10.11.5 (or more recent), version MacOS systems Sierra downloads unnoticed. You will then be prompted to install this version.

Click on the install button

During the installation of MacOS, the PC restarts several times. If this version does not suit you (the performance of the MacBook has dropped), “roll back” to the previous one (for example, OS X El Capitan), with which the PC performance was very satisfactory.

Restoring MacOS from a backup

For example, we take a “rollback” from MacOS Sierra (10.12) back to OS X El Capitan (10.11) or OS X Yosemite (10.10). Let's say there are backups made in Time app Machine before installing MacOS Sierra.

Important! You can only restore a MacOS system from a backup to the same MacBook. Trying to transfer your copy of the MacOS system with data to another PC in this way is useless. Use other methods.

  1. Connect an external drive to your MacBook and save existing files in Time Machine, naming the new copy MacOS Sierra.
  2. Open your previous copy of OS X Yosemite with Time Machine on a different drive after connecting it to your MacBook.
  3. Restart your MacBook while holding down Command+R on your keyboard. The familiar MacOS recovery menu will open.
  4. From the OS X Utilities menu, select Restore from Backup copies of Time Machine".
  5. Once in the “Recover from Time Machine” recovery window, click on “Continue”, and then specify the source - the disk with the OS X El Capitan “backup”.
  6. The saved copy should be: In the case of OS X El Capitan, the MacOS version should be 10.11.x. Click the Continue button. Specify installation disk to restore from a copy, click on “Restore”.

Ready! The OS X El Capitan version will be reinstalled.

Transferring a copy of the operating system and your data to another MacBook

Go to Programs/Utilities and open Migration Assistant. The structure of your files and folders will be preserved.

Click to continue

When running, the application requires closing all other running programs.

If both computers are working, but you still want to duplicate your version of MacOS and all data on the second computer, connect the computers to each other using network cable LAN, by wireless network Wi-Fi. Connecting directly using a Thunderbolt or FireWire cable will require running your previous Mac in backup mode, making the Assistant experience a little more complicated. However, both methods work clearly. You can connect an external disk with a backup copy to the new PC instead of the previous PC - in this case, the operation of the Assistant on the new PC will not change significantly.

So, the procedure is as follows. Taken as an example normal mode operation of the previous PC with Assistant.


All! The copy session has started. This can take anywhere from 30 minutes to two hours, depending on the amount of data and the performance of both Macs.

Problems encountered when reinstalling MacOS

Problems when updating or “rolling back” may be as follows.

  1. No recent backups. You once disabled backup yourself. Copy your files now to avoid losing them by starting the process manually. Enable backup.
  2. Error on next backup or when recovering personal data from previous copy. External drive, which has been recorded so far, is unsuitable for further use. Contact an Apple service center or certified computer repair shop to restore your data. This procedure is not free.
  3. Error on next MacOS update. Your Mac PC may no longer be supported. This happens once every few years. All you have to do is use current version MacOS before replacing your Apple PC.
  4. The computer began to work noticeably slower than before the update. Minimum system requirements next new version equal or exceeded specifications your PC. “Roll back” to any of the previous ones MacOS versions. Typically, Apple tries to prevent this from happening - it simply stops supporting older computers, just like installing iOS version 10.x is no longer possible.
  5. Your PC after several active years suddenly began to freeze despite the fact that you did not update MacOS. Maybe it's time to replace the internal HDD/SSD drive? Try to do backup copy your important data before replacing the internal disk - while something is still being read from it.
  6. It is impossible to “roll back” to one of the previous ones installed versions MacOS. The “rollback” must be done gradually. If there are no previous backups, download a new “image” and “rollback” first to this version, and then repeat the “rollback” to an even higher one earlier version MacOS.

Reinstalling MacOS - “on top” or “from scratch” - is not difficult. It is only important to secure your data. This real way extend the life of your beloved MacBook for another number of years. You will succeed!

We all know about stability and high performance operating rooms Apple systems, but over time, many notice that their nimble poppies begin to “think” when performing this or that action.

There may be many reasons for this, but the main one is one. Each time you update the system, you inevitably drag new version all accumulated over the years system garbage and other nasty things. And no matter what the developers say, this is true. Therefore, it will not be superfluous sometimes (it is enough through a release, that is, once every 2 years) to install the system from scratch. Of course, what to click in App Store The “update” button is much easier, but a clean installation will return the mac to its former speed, and you will enjoy using it!
