We tell you how to protect your data.
Have you forgotten the administrator password to turn on your Mac? No problem, Apple has a solution. In just a couple of minutes you can easily reset your password and set a new one...
But this can be done by ANY stranger who gains access to your Mac.
Let's understand this feature of OS X.
How to reset MacBook password
Let's be optimistic and decide that it is you, and not someone else, who needs to change the password on your MacBook.
So, after unsuccessful attempts to log into your account, the only solution left is to reset your password.
1. We need to turn off the laptop. While at the password entry screen, hold down the Power key until your MacBook turns off. Now turn on the MacBook and hold down the key combination Command+R. Hold it until a thin loading bar appears.
2. We're in Recovery Mode. Opening Utilities -> Terminal.
3. Enter the following command resetpassword and press Enter.
4. In the window that opens, enter a new password and, if necessary, a hint.
5. Just restart your Mac and sign in with a new password.
The system will immediately prompt you to update the password for Keychains, but without knowing the previous password, you will not be able to do this.
After loading, OS X will begin to require you to enter your old keychain password. If you don't know it, it's best to create a new one A bunch of keys(after all, you probably remember the passwords for your Apple ID account and other services).
How to protect yourself from data theft
Until you enter the password for the old keychain or create a new one, the system behaves extremely strangely. Working with applications is very difficult - they freeze, slow down and stop responding.
However, copying the necessary information in this mode to an external drive is as easy as shelling pears. And if there is confidential information on your Mac, you will undoubtedly notice its loss, but it will be too late.
In order to protect yourself from such a situation, it is enough to follow a few simple steps that will protect you from such free access to password reset.
1. Open Settings -> Protection and Security, remove the security lock in the lower left corner and move to the tab FileVault.
2. Tap the key Enable FileVaul.
3. When the system asks you to select an unlock type, select the option you are interested in. Allow my iCloud account to remove protection from my drive- more preferable. Click Continue.
Now all that remains is to wait until the system finishes encrypting the disk. The option of just resetting using a terminal will not work on an encrypted disk, but your data will be in perfect order.
The macOS feature that lets you unlock your Mac with Apple Watch provides security and convenience. However, a problem may arise if the feature stops working properly.
If unlocking your Mac using Apple Watch isn't working for you, here are some solutions you can try.
The most common problem with this feature is that the light spins for a couple of seconds but doesn't unlock the Mac and ends up popping up a sign asking for a password. In this situation, solution #8 is suitable. You may have other cases, but one of the solutions should definitely help.
How to fix unlocking problemsMac by usingApple Watch
Solution 1: Make sure you entered your password correctlyMac while loading.
After you enable Apple Watch unlock, you will still have to enter your passcode if you restart your Mac. This is not a bug, it is a security measure designed specifically. Every time you restart your computer, you will first have to enter the password manually. Then, if your Mac goes to sleep, you can unlock it using your Apple Watch.
Solution 2: Make sure you entered your password correctlyApple Watch.
Like your Mac password, you'll also have to enter your Apple Watch password manually first. This is also a security measure designed to ensure that no one else can unlock your Mac.
Solution 3: Turn the feature on and off.
On a Mac, go to > System Preferences > Safety. Select a tab Basic, then remove and check the box next to AllowApple Watch unlockMac.
Solution 4:Make sure you are logged in to the same account on both devices.
On a Mac, go to > System Preferences > iCloud and make sure the account here is the same as on the Apple Watch in the Watch app > General > Accounts.
If the account does not match, you will not be able to use the unlock feature.
Solution 5: Make sure Bluetooth and Wi-Fi are turned on on your Mac.
Bluetooth and Wi-Fi must be turned on to transfer information. If they're turned off, Apple Watch won't be able to connect to your Mac to unlock it.
Solution 6: Check thatMac function disabledInternet Sharing
On a Mac, go to > System Preferences > Sharing and make sure sharing is turned off.
Solution 7: Check thatApple Watch was no more than an arm's length away fromMac.
This is understandable, but you still have to be near the Mac to unlock it for hours.
Solution 8: reboot All.
If all else fails, simply restart your Mac and Apple Watch. You may need to restart your Mac more than once for the feature to work properly.
The following options are possible: When the system boots, after the apple a message is displayed: “Enter the system lock PIN to unlock this Mac,” below you need to enter a four-digit code. The same in English: enter your system lock pin code to unlock this mac.
Immediately after turning on the MacBook or iMac, a lock appears with a field for entering the unlock code. It is possible that such a lock will appear when you hold down the alt option key when you need to boot from another disk. 
After passing through the loading bar, a window may open with the following message: “Your computer is turned off. Please try again in 60 minutes” or “Your mac is disabled. Try again in 60 minutes” 
There are two types of Mac locking: at the EFI firmware level and at the MacOS level. In each case, you must enter a password to boot into macOS. If there is an EFI password (the password for the firmware of the computer’s motherboard), then without knowing it it is impossible to boot from an external drive or reinstall MacOS.
The model name can be recognized by the serial number on the bottom cover of the MacBook or the leg of the aimak.
We do not completely disassemble the device (with the exception of new iMac models); in order to remove the lock, you just need to unscrew the bottom cover of the MacBook or remove the iMac display. The service programmer is connected via a special connector on the motherboard (logicboard). All MacBook, iMac, Mac mini and Mac Pro models can be disassembled in 5 to 30 minutes. Before assembly, the computer is cleaned from dust. Unlocking a Mac leaves no traces of intervention; the device is transferred to the client in the same form.

Without it, you cannot install a new application, make important changes in settings, or log in (optional). Have you lost or forgotten the “magic word”? Do not worry! There are several simple ways to recover or change the password for your Mas.
How to recover a forgotten Mac password
First, let us remind you: the number of attempts to enter a password is not limited, after 3-5-10 attempts OS X you won't get banned. If you can’t remember your password using the guessing method... then let’s figure it out.
Clue
You don't have to reset or change your password right away—you may be able to remember it thanks to a password hint. To get it enter the wrong password three times. OS X will then realize that something is wrong and offer you a hint. You set it when you came up with a password for the very first time. Perhaps this will refresh your memory:
The downside of the method is that it is not necessary to set a hint, so you (like me) may have simply not done this at one time.
