To fully work with Mac OS, you need to be able to perform various operations: resetting your Macbook Pro to factory settings, returning lost data from backup, recovery forgotten password... All this can be done on a Mac using the built-in system tools, but in the most difficult situations, the use of installation disk.

Factory reset

If Mac OS on a Macbook Pro or another Apple computer is not working properly and you want to return standard settings, then take care of creating a backup copy of the data in advance, since all information will be deleted during the reset. To create a backup copy of the OS, it is recommended to use the utility Time machine... To store a backup, you will need external hard a disk formatted with Mac OS Extended (Journaled).

After adjusting the settings, the Time Machine slider will be set to On. A complete system backup takes several hours. After creating a backup, you can proceed to returning the factory settings to the OS:

After the disk formatting process is complete and the OS has been reset to factory defaults, exit Disk Utility. Reinstall Mac OS X again using the appropriate item in the Utilities window.

Recovering data from a backup

If you are confused about creating a backup before the reset macbook settings Pro, you can quickly recover lost files if necessary.

After the calculation of the time required to transfer files is completed, click "Restore". A warning will appear that the disk you are recovering to will be completely cleared of information. Click Continue. After the repair is complete, restart your computer. At startup, you will see the system as it was at the time of the backup. All changes made after this event will be canceled.

Password recovery

There are three ways to reset a password that a user has forgotten:

• Using the installation disc.
• By applying Apple ID recovery.
• Using the terminal in recovery mode.

If you have a Mac OS X installation disc, it won't take long to reset your password:

A reset wizard will help you get rid of the key that the user has forgotten and configure new Password... This is the most quick waybut if you don't have mac disk OS, then nothing will work. In this case, you can try to enter the password incorrectly three times - the recovery window via Apple ID will appear.

However, there is a condition here: the function of password recovery via Apple ID must be enabled in the Mac settings. If you have not activated this feature, use the third method, which works on all versions of Mac OS and does not impose any requirements.

After resetting the password, you need to reboot the OS. At startup, a message appears stating that the system was unable to unlock the keychain for login.

What the best way recover Mac without recovery partition?

In the event of a serious problem, you may need to reinstall the entire operating room mac systems using the recovery partition. But how do you recover a Mac that is missing a recovery partition?

It is possible to restore a Mac without a recovery partition, but it can be difficult (especially on older mac computers). You have two approaches:

• Use Internet Recovery to reinstall OS X on a Mac with a missing recovery partition.
• Create an OS X installation disc from your old USB Thumb Drive and reinstall OS X.

We'll cover both of these options in this feature - but first, let's quickly explain what a recovery partition is.

How to recover Mac without recovery partition: what is OS X recovery partition? (What are sections in general?)

Most people don't really think about hard drives in terms of partitions (and volumes). They just see the whole disc as one.

It is usually difficult to have a single volume, but then it is split into several areas called "sections". Think of your hard drive as a home and partitions as different rooms.

You are used to seeing only one room in the house, which has its own desktop, folders and applications. But there are four partitions, and one is used as a last resort when you can completely reinstall OS X. Even if you completely wipe OS X and start over from scratch, the recovery partition will be there to get in and reinstall OS X.

This is a problem if the recovery partition is missing. After all, how are you going to reinstall OS X from scratch? This happens: if you put a new hDD on your Mac, or accidentally destroyed the recovery partition by installing Windows, Linux, or another OS on your Mac, you may not have a recovery partition to work with.

How to recover Mac without recovery partition: how to check if your recovery partition is working

You should first check that your Mac definitely doesn't have a working recovery partition. It used to be that pressing the Option key in OS X would create bootable disks (including the recovery partition). But now it only displays system drives OS X (usually just your primary hard drive).

Here's how to boot into Recovery Drive:

1. Shut down your Mac. (Apple menu\u003e Shut Down.)
2. Hold down the Command and R keys at the same time and press the power button.
3. Continue holding Command and R until the Apple logo appears on the screen. Release the keys and wait for the Mac to shut down. (This will take longer than usual.)
4. You should be faced with a screen that says OS X Utilities. This is the recovery partition. If you have this, stop worrying. You are good to go.

If your Mac boots into OS X, or if you're faced with a completely blank screen, then you don't have a recovery partition. If your Mac boots into OS X, you can also check Terminal to see if there is a recovery partition:

1. Open terminal.
2. enter Discout list.

You should see a list of all volumes and partitions on your computer. The first disk (/ dev / disk0) should have a partition (usually labeled "3" with Apple_Boot Recovery HD after it). Please try again using the Command-R process. Before proceeding to reinstall OS X, try a few of these tips:

• Reset your PRAM. Complete mac work and hold Command-Option-PR while loading. Wait for the chimes and release.
• Check your keyboard (especially if it's a Bluetooth keyboard). Use a wired keyboard whenever possible.

Ok, so either your recovery partition is missing or not working and you've tried everything. So it's time to take a look at reinstalling OS X. You should first take the time to back up OS X if you can use Time Machine. This will allow you to restore all your files, folders and applications after reinstalling OS X.

How to Recover Mac without a Recovery Partition: Use Internet Recovery to Reinstall OS X

If you don't have a recovery partition on your Mac, you need to reinstall OS X. Even if OS X is running, you should probably consider reinstalling, because a missing recovery partition is not a good sign. But mostly you will run into this problem when OS X is down and you cannot restore it in the usual way.

The first approach is to use the Internet Recovery feature. New Mac can be loaded directly from an Internet connection, even without using a recovery drive. Here's how to use OS X Internet Recovery:

1. Shut down your Mac.
2. Hold Command-Option-R and press the Power button.
3. Hold the keys until you see a spinning globe and the message “Starting internet recovery. It can take some time ".
4. The message will be replaced with a progress bar. Wait for it to be filled.
5. Wait for OS X Utilities to appear.
6. Click Reinstall OS X and follow the installation procedure.

There are problems with Internet Recovery. It only works with networks that use WEP and WPA security. This is the majority of household wi-Fi networksbut if you are on a proxy or PPPoE then you will have problems. In these cases, it's usually best to find another network rather than create a USB Recovery Stick (our next step). If you have an online restore, use it to reinstall OS X if possible.

How to Recover Mac without Recovery Partition: Create Bootable OS X Installer from USB Drive

If you don't have online recovery, you are left with the final option. This is done to create a bootable installer from a USB stick (at least 8GB in size). Note that this will completely erase the USB stick, so be careful to erase all files from it first.

There are two ways to create a USB flash drive installer. One is to use the terminal, the second is to use the DiskMaker X application. Here is the terminal approach.

Open the Applications folder and select the Install OS X El Capitan checkbox. If not, open App Store and click Buy, then click Download next to El Capitan. Wait for the file to download completely.

1. Attach a USB stick.

2. Open disk utility.

3. Select the volume (under "External") on the sidebar. Volume is at the top, not the section (which is at the bottom).

4. Click Erase.

5. Make sure the Name field is Untitled. Don't change it. Click Erase.

6. Open terminal.

7. Cut and paste the following line into the terminal:

sudo / Applications / Install OS X El Capitan.app/Contents/Resources/createinstallmedia -volume / Volumes / Untitled / -applicationpath / Applications / Install OS X El Capitan.app/

You will need to enter your administrator password. Then enter "y" and press Return. It will first drain your flash drive and then turn it into a bootable installer.

8. Wait for the process to complete.

If the process is a bit tricky then consider downloading DiskMaker X.This program automates the process of creating an OS X installer.

How to Recover Mac without a Recovery Partition: How to Use OS X Bootable Installer

Then follow these steps to use the bootable installer:

1. Make sure OS X bootable installer (USB stick) is connected.
2. Shut down your Mac.
3. Hold the option and press the power button.
4. A Boot Device List window will appear with a yellow disc with OS X El Capitan installation underneath.
5. Select it and press Return. Wait for the progress bar to fill.
6. Select "Disk Utility".
7. Select the drive under "Internal" (primary hard drive).
8. Click Erase.
9. Give the disk a name; Macintosh HD is traditional, but you can choose. Make sure the format is OS X Extended (Journaled) and the schema is the GUID Partition Map.
10. Click Erase.
11. Click Finish.
12. Choose Disk Utility\u003e Exit Utility.
13. Select Install OS X and click Continue.
14. Follow OS X settings.
15. Select Macintosh HD as the installation disc, if presented, and click Install.

OS X will now be installed on your hard drive from the OS X Boot Installer. The entire process can take about half an hour. You will then have a blank OS X installation along with a new recovery partition.

If your Mac is frozen and not responding, should help forced reboot... To execute it press and hold the power button until mac screen turns off, and then turn on the computer as usual.

Attention! With this shutdown, unsaved data in applications will most likely be lost.

2. Removing removable media

Eject (⏏) or F12

During a crash of a Mac with an optical drive and a disc inside, the system may fail to boot from it and freeze. Press the ⏏ (Eject) or F12 key on your keyboard, or press and hold the mouse or trackpad button to eject the media.

3. Selecting a boot disk

If you have multiple disks installed on your Mac and you cannot boot from the default disk, you can open the bootable disks selection dialog and select the desired media manually. To do this, press and hold the ⌥ (Option) key immediately after turning on the computer.

4. Boot from CD or DVD

Likewise, you can instruct your Mac to boot from disk from built-in or external optical drive... In this case, press and hold the C key on the keyboard.

5. Download from server

⌥N (Option + N)

Once you have a NetBoot server on your local machine that has a bootable system image, you can try to start the Mac using it. To do this, press and hold the ⌥N (Option + N) key combination.

This boot method does not work on computers with an Apple T2 processor.

6. Run in Target Disk Mode

If the Mac does not want to start in any way, then you can switch its mode external drive and copy important filesby connecting to another computer using a FireWire, Thunderbolt, or USB-C cable. To start in this mode, press and hold the T key when turning on.

7. Launch in verbose mode

⌘V (Command + V)

By default, macOS does not display a detailed startup log, showing only a loading bar. When problems arise, you can enable a verbose log to help you understand at what stage of the download the error occurs. To do this, when turned on, press the combination ⌘V (Command + V).

8. Start in safe mode

When your Mac won't boot normally, it's worth trying to launch Safe Mode. It checks the disk and includes only the basic components of the system, which allows you to determine which named programs or services are causing errors. To upload to safe mode press and hold the ⇧ (Shift) key.

9. Single user mode

⌘S (Command + S)

This mode launches the system in an even more stripped-down version - only command line... Nevertheless, with its help, specialists will be able to diagnose and correct errors if any. Press ⌘S (Command + S) to start in single-user mode.

10. Run diagnostics

macOS has built-in hardware diagnostic software to help diagnose hardware problems. Press and hold D to start diagnostics.

11. Run network diagnostics

⌥D (Option + D)

If boot disk is damaged, the diagnostic test will not run. In such cases, network diagnostics will help, allowing you to run the test over the Internet. To do this, press the combination ⌥D (Option + D)

12. Recovery mode

⌘R (Command + R)

When booted in recovery mode, you can access Disk Utility, reinstall macOS, and restore data from a created backup. Press and hold ⌘R (Command + R) to enter recovery mode.

If your Mac has a firmware password, you'll need to enter it.

13. Network Recovery Mode

⌥⌘R (Option + Command + R)

A mode similar to the previous one, which, in the presence of the Internet, allows you to reinstall macOS by downloading the system distribution kit directly from Apple servers. To use it, press ⌥⌘R (Option + Command + R).

14. Reset NVRAM or PRAM

⌥⌘PR (Option + Command + P + R)

If you have problems with the display, speakers, cooling fans, or other Mac components, you can try to resolve them by resetting NVRAM or PRAM. To do this, press and hold the ⌥⌘PR keys (Option + Command + P + R) at startup.

If a firmware password is set on the Mac, this method will not work.

15. Reset SMC

A more radical way to reset is to return to the default system management controller (SMC) settings. It is applied if the previous method did not help. Resetting the SMC is done differently depending on the Mac model.

On stationary computers you need to turn off your Mac, unplug the power cord, and wait 15 seconds. Then reconnect the cable, wait five seconds and press the power button to turn it on.

On laptops with a removable battery you must turn off your Mac, remove the battery, and then press and hold the power button for five seconds. After that, you need to install the battery and press the button to turn it on.

On laptops with a non-removable battery shut down your Mac and hold down Shift + Command + Option with the power button for ten seconds. After that, release all keys and press the power button to turn on.

On MacBook Pro with Touch ID, the sensor button is also the power button.

In order to restore the system, we need:

External media with a Mac OS backup;

Mac Book, Mac Book Pro, Mac Book Air, iMac, Mac mini;

About an hour or less depends on the size of the backup and the performance of the Mac.

Step 1. Connect your Time Machine backup media to your Mac.

Step 2. Restart your Mac by clicking the "Apple" menu in the upper left corner, select "Restart".

Step 3. When your Mac boots up (a gray screen appears), press and hold Command (⌘) + R.

Step 4. Select the external media with the backup, the recovery drive and the date of the restored backup.

Once the OS X utilities have loaded, select "Restore from Time Machine Backup".

Read the general information and click "Continue".

Select the recovery disk (the media on which the backup is located).

The next step is to select a backup, I recommend choosing the most recent one, since it will contain last changes in system.

After that, you need to select the disk to which the system will be restored.

At the end, a message will appear stating that the restore was successful, after which the Mac will reboot and on the next boot you will see the restored Mac OS X.

Recovering data from Time Machine backups.

In order to recover files (photos, videos, music) made using Time Machine, enter Time Machine by clicking on the icon in the right upper corner and select "Enter Time Machine".

If the backup media is not connected, you will see the error "Can't find your drive reserve copy Time Machine. "To fix this error, connect the media to your Mac.

If a media is connected, you will see an interface that will allow you to travel back in time and view early changes to your files using the arrow or timeline on the right side of the screen. To recover files, select one or select several and click the "Recover" button.

In my opinion, file / system recovery has never been so elegant, beautiful and easy to do as in the Time Michine utility.
