In this article, we’ll explore the pros and cons of turning on FileVault disk encryption, helping you decide if it’s the right choice for your needs.
What is FileVault?
FileVault is a full-disk encryption feature that encrypts all data stored on your Mac, including documents, images, videos, and more. It uses the Advanced Encryption Standard (AES) algorithm to encrypt data at rest, and it also provides a secure boot process to ensure that your Mac boots with the encrypted data.
Benefits of FileVault
Here are some of the benefits of turning on FileVault disk encryption:

Drawbacks of FileVault
While FileVault is a powerful tool, there are some drawbacks to consider:
