What is FileVault?
FileVault is a built-in security system on Macbook that supports boot disk encryption (hard drive) and is responsible for securing HDD and SSD hard drives for Mac. FileVault encrypts the data on your hard drive so that unauthorized users cannot access your information.
FileVault uses XTS-AES 128 block cipher technology and 256GB key. After enabling FileVault, it automatically encrypts all data currently on the hard drive. When there are any new or changed data, they will also be encrypted automatically. It forces you to enter your password when you wake up from sleep or open the screensaver.
FileVault was introduced in 2003 but is not well known. Until 2011 on MacOS X 10.7 Lion, Apple released a more efficient encryption system called: FileVault 2. After enabling FileVault, the Macbook will prompt you for a password and have the choice to create a Recovery Key or can use it. your iCloud account as the passcode. Even if you move that hard drive to another machine, your data is safe.
If you have an iMac Pro or Macbook that uses Apple’s T2 Security Chip, the data on your drive is automatically encrypted. However, enabling FileVault provides further protection by requiring a login password to decrypt your data.
Some limitations of FileVault
One limitation of FileVault is that the hard drive password will not be saved, so if you forget this password or your hard drive is damaged, sometimes you will permanently lose the data on the drive. And if you use iCloud as your password, sometimes you still have a few Apple options to get your password back.
And another limitation is that since turning on FileVault, the device will automatically lock the device when you are not using it. Every time you turn on your Mac or turn it back on when it sleeps, you always have to enter the password. This will take a bit of time. And each time the CPU runs the encryption, it takes a little more time.
Therefore, if there is no important data, you can forgo turning on FileVault to avoid annoying steps during use.
