Based on materials from yablyk

Sometimes in the operating system MacBook Pro or MacBook Air crashes. The same thing often happens with software. In both situations, it becomes necessary to return to the original settings. In general, Mac OS is stable, but even it is not immune from troubles. Anything can happen.

In a MacBook situation, a factory reset involves a complete reinstallation of the system. This will erase all data. The device will become empty, as if you just purchased it. Therefore, before producing full reset, backup is required. It is advisable to save a copy on a separate medium. The operation itself is simple, but a stable network connection is required. How to reset your MacBook to factory settings - see this manual.

Most experienced iOS device owners probably make copies regularly. But if you forgot about this important procedure, start it immediately. Only after completion can you click on the reset item.

Why is backup so important? Yes, simply because if you do not save a copy of all the data that is important to you, then in the future you will not be able to return it. That is, you will irrevocably lose your data.

The Apple company recommends checking for updates first, and then updating and connecting the device to a PC / laptop to create a copy manually. Or you can do even easier - enter the "cloud", and the service itself will do its job.

Mac OS reinstallation method

Make sure the network is connected before performing a factory reset. The MacBook also needs to be connected to the network. Further, the algorithm of actions will be as follows:

We send the device to reboot.
In the process, we clamp the set of elements Cmnd + R.
We are waiting for the download of the recovery mode operating system.
Select the disk utility section in the utilities window.
Select the boot disk and move on to the additional erase section.
Select the operating system from the selected disk and confirm its erasure.
When formatting is complete, return to the utilities section.
We select the point of reinstalling the operating system.

Further, the download of the operating system will take place fully automatically through the network. After that, following the instructions on the display, you can re-install the operating system. This operation will not take much time. The main thing is to monitor stability network connection... A sudden rupture can occur due to the battery running out of charge, which will cause trouble.

Even ahead of time, it would be good to attend to the creation of a bootable USB flash drive. Or a disk - if it came in the original configuration. And to create a backup from the hard drive, you can use external software.

Factory reset: steps

Sometimes problems with the "braking" of the device are easily solved by resetting the system settings and eliminating errors. Usually this method is suitable when there are problems with the download speed of the system. If this method turns out to be useful, then a factory reset is not required. Of course, knowing how to do it is essential - just in case.

So, to reset, we perform the following steps:

Turn off the MacBook.
Clamp the set of elements Cmnd + Opt + P + R (including the battery).
We keep all this from the moment when the sounds of the switch-on will play two times.
We check the download speed and system settings.

That's all. But if the problem persists, try resetting to the original settings.

Password characters are required to log into the PC. It can also be requested when installing some software. And these symbols are generated during the initial setup of the PC. Also, the password can be generated when adding a new account. However, the situation when the owner of an iOS device does not remember the password characters and log in is quite common.

If this happened to you, try returning the password through:

Recovery procedure via ID.
Using a boot disk.
Reset by means of recovery mode.

And the very first thing to do in such an unpleasant situation is to refer to the hint about the set password symbols. Maybe it will work out, return it yourself? For this purpose, deliberately incorrect characters are driven in three times, and then the hint recorded by the owner of the MacBook (or other "apple" device) will pop up on the display.

We work with Apple ID

How the operation of resetting password characters via ID is performed is described in detail on the company's technical support resource. On operating systems from version 10 and older, the system is tied to an ID, therefore, at the step of setting up a PC, it is better to check the box next to the password reset section using your ID.

You need to drive in the wrong password characters three times. After the system will be prompted to perform a recovery (a prompt will also pop up). You will need to give consent, drive in the identifier and click on the password reset section. A new set of keys will be generated, but the old one will not disappear anywhere. But if you ever remember your old password, you can use it without any problems.

Using a boot element

To change the password characters through the boot disk, you will need access to it. Modern lines of MacBooks are not equipped with such in principle. So this method is only for those owners of "apple" laptops who had a disk and did not go anywhere. You can also prepare in advance bootable USB drive in case you have any trouble cleaning.

You can drop the password in this way through the following steps:

We insert the disc.
When loading the PC, hold down the "C" element.
We are waiting for the installer to appear.
We open the utilities section.
Choose "Password Reset".
We stop on the disk with the system and the user profile on which you want to reset.
We drive in "resetpassword".
Click on "Enter".
We drive in new password characters.

Now you can safely reboot the device and generate new password characters.

Turning to MacBook recovery mode

The procedure for resetting macbook password characters through recovery mode does not require binding to an ID or installation disk. The algorithm of actions will be as follows:

During the reboot, hold down the Command + R set of elements.
Wait for the transition to the recovery mode.
Select the bootloader language.
Go to the terminal section using the utility panel.
Driving in (double) new characters in the pop-up window.
Confirmation of the change of characters.
