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 already on sale with installed system. 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 new system installed on top of the old one without full formatting and preserving user data.

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. For previous versions, for example Mac OS X, in fact, there will be no differences, but it is still recommended to upgrade to latest version, if your device supports it.

Operating system installation

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. Creation bootable flash drive.
  3. System installation.

For Reserve copy data use external storage and the Time Machine program, which automatically starts when connected removable media. The utility will ask whether to use external drive for backup, click "Use". as a backup drive."

After the backup is complete, 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 - 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 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, as 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.

That is why Mac user you need to know how to reinstall Mac OS X via Recovery yourself. This reinstallation is possible in all operating systems for Apple computers, starting with Mac OS X 10.7 Lion. Recovery mode allows you, if you have an Internet connection, to download the current version of the operating system and install it without writing files to media. Reinstalling Mac OS X via Recovery is very convenient for MacBook owners, since most new laptops are released without optical drive, and creating a bootable USB flash drive can be quite a hassle, especially for a beginner.

Apple developers have provided the opportunity not only to download the operating system from the network, but also to restore from a backup using Time Machine, and also to correct files using a special “Disk Utility”. If you notice that your Mac's operating system is not working as well as before, you need to start troubleshooting the problem by checking the disk with the standard Disk Utility. If troubleshooting does not help, then you should think about restoring Mac OS X via Time Machine or downloading operating system files from the Internet. We'll look at how to reinstall Mac OS X from the Internet.
