To protect the data security of Apple Mac computers, you can use built-in system tools.

When your beloved Apple Computer suffers theft or illegal computer account intrusion, is there a way to prevent data from being stolen on the computer? In this article, we will introduce two simple and effective methods to protect our Mac computer data.

FileVault disk encryption

This is a software-based encryption tool called FileVault. This software can encrypt the data on your Mac device, so intruders will not be able to access your files. If you are using the OS X Yosemite system, congratulations-you are probably already using FileVault because it is a built-in system tool.

To confirm whether you are using the service, you can open Preferences-Security & privacy-FileVault. Manually enable this function. You can click the lock icon in the lower left corner. It will unlock and request you to enter the Administrator name and password, and then click Open FileVault tab.

Finally, the system will provide a recovery key, which can be used once you need to reset the password. Therefore, you must store the key in a safe place. If not, it can be stored on the Apple Server. To solve this problem, you need to create three security questions and then answer these questions correctly when extracting the key.

After the configuration is complete, restart the Mac device, and FileVault will encrypt the files in the Mac hard disk. You can continue to use Mac to do other things during the encryption process.

Firmware Password

In fact, even if FileVault encrypts your files, some may also take your laptop and enter the recovery mode to format your hard disk. In the end, they claim that they are the host of the computer. One disadvantage of FileVault is that it does prevent your data from being peeked, but it does not prevent thieves from stealing your computer, because after the thief reinstalls the OS X system, the computer will not retain any previous information.

That's why you need a firmware password! This method is also very simple-use hardware-based encryption tools. You can set the firmware password in the system "Recovery Mode.
