Macbook is a product line that always makes customers satisfied by the ability to work effectively, beautifully designed and quality. In addition, this is a well-known operating system with high security, so that Mac users should set their own lock screen habits to improve data security.

Locking your screen or putting your MacBook to sleep (sleep) is something you need to do when you can't sit in front of the machine. In sleep mode, your Mac is locked again (provided you have previously set up a lock password); At the same time, the applications you are using in progress will quickly return to the active state when you return to use the device.

There are many ways to help you lock your MacBook. But in this article Network Administrator will summarize 7 methods. In the first 5 ways, you will need to set a login password, and the following 2 ways are not - very convenient when you close the Mac cover without entering the password when reopening.

Before starting, you need to set the login password for Mac according to the following instructions: Go to System Preferences> Security & Privacy and check the box to Require Password after sleep or screen saver begins (requires a password after running mode sleep or screen saver). In the drop down menu, you can set the time from immediately to 8 hours (8 hours).

After you have installed the required password, you will have the following options to lock the MacBook quickly and safely:

1. Close the lid

This is the simplest way anyone can perform anywhere. Just close the lid of your Mac and you've locked the screen yourself. When you turn on the computer, you only need to enter the password that you set up earlier.

2. Use the Apple logo in the menu bar

The next way is to simply click on the Apple logo located at the top left corner of the screen and select Sleep so you can turn off the screen.

3. Combine keyboard shortcuts

If anyone who is familiar with the operation on the computer keyboard can apply this method.

1. Use Control-Shift-Power (power button) to lock your MacBook (with older MacBooks using an optical drive, you use Control-Shift-Eject).
2. Use Command-Option-Power to bring MacBook back to sleep mode (with old MacBooks using optical drives, press Command-Option-Eject).

Keep in mind that when you lock the screen or put Mac to sleep, the ultimate goal is to turn off your MacBook screen. However, if you want to save power for the Mac, you can leave the Mac in sleep mode because at this time the CPU is set to low voltage mode, the hard drive is reduced the rotation speed, and the underground tasks are blocked. again.

4. Use Access keychain function

The above methods only work when you use a login password, but if you don't like every time you work, each time you enter a password, you can try the following:

1. Open the Utilities folder located in Applications
2. Open Keychain Access
3. Go to Keychain Access> Preferences
4. Check the Show keychain status in the bar menu

The lock icon will appear next to the Wi-Fi icon in the menu above the right corner of the screen. Click here and select Lock Screen to lock Mac.

5. Request a password

Another easy way to apply is to request an access password when logging in. To do this, open System Preferences -> Security and check the box Require password after sleep or screen saver begins , the system will show the option time for users to choose:

You can check again by setting the computer to Sleep state. But sometimes this process is not the best option, because there are programs or applications that cannot be interrupted while operating. And to fix this case, you need to interfere with the ScreenSaver mode setting.

6. Reset ScreenSaver mode

We can completely do this in two ways: assign to any corner of the exposé or create a shortcut inside the Dock.

Expose's Hot-Corner assignment

In System Preferences, you select Expose and Spaces control panel . Here you will see a small section called Active Screen Corners with 4 options corresponding to 4 screen corners, select any corner and Start Screen Saver from the menu list:

Create shortcut inside Dock

This way is a bit too picky but a bit more laborious, but if the operation is successful, we will have an icon to help protect the screen and lock the Mac right on the Dock. Specifically:

1. First open the Finder and go to Go> Go to Folder .
2. In the box that appears, enter /System/Library/Frameworks/ScreenSaver.framework/Versions/A/Resources/ and click Go.
3. In the Resources folder that you are directed to, find the ScreenSaverEngine file and drag it to the Dock.

Now you can click the ScreenSaverEngine icon in the Dock bar to launch the screen saver.

To use, you just need to click on this file on the Dock , the system will activate ScreenSaver mode and request access password if you want to log in.

7. Re-enable Fast User Switching mode

1. Go to System Preferences> Users & Groups
2. Click the lock icon located at the bottom left and enter the login password to make changes on the Mac.
3. After entering the password, click on Login Options
4. You select Show fast user switch menu as

Now you can click on the account icon at the top right corner and select Login Window to lock Mac or switch to another user account if available.
