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.
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.
If anyone who is familiar with the operation on the computer keyboard can apply this method.
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.
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:
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.
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.
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:
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.
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.
I wish you all success!
