How secure is FileVault?
FileVault uses XTS-AES-128 encryption with a 256-bit key so it is very secure. The number of key combination in AES-128 is 3.4*10^38. Assuming we use a computer which can calculate a million keys per second during a brute force attack then the time required to crack it will be 1.07^25 years or 10 million billion billion years.
Should I use Apple FileVault?
There’s no need to use FileVault just because Apple included it on the machine. There are many attendant risks to using FileVault that are not good for you or the machine. Such as catastrophic loss of data and files.

How does FileVault work?
FileVault is Apple’s implementation of encrypting your data on macOS and Mac hardware. It will encrypt all of your data on your startup disk (although you can also encrypt your Time Machine backups as well) and once enabled, it will encrypt your data on the fly and will work seamlessly in the background.
Does FileVault take up more space?
The new FileVault is block level full-disk encryption, and as such exists completely outside the filesystem, and therefore it takes up zero filesystem space. It might take up a small amount of actual disk space, but the number you see when you “Get Info” your disk in Mac OS X will never be affected by Lion’s new FileVault.
Is FileVault recommended?
Although FileVault is so easy to use, it is not suitable for everyone. It is not recommended for those who do not need such high level of security and especially not recommended for those who are likely to forget or lose passwords.
What is FileVault disk encryption?
FileVault is macOS’s built-in disk encryption feature. It’s designed to encrypt your Mac’s hard drive and all of the files located on the drive using 128-bit AES encryption with a 256-bit key. Once FileVault is enabled on your Mac, all existing data will be encrypted.
