What are the differences between FileVault and an encrypting disk image?

What are the differences between FileVault and an encrypting disk image?

FileVault is a full disk encryption feature built into macOS, while an encrypting disk image is a specific file that can be created to encrypt individual files or folders.

Which one is more secure?

FileVault generally offers better security for the entire system, as it encrypts the whole disk. An encrypting disk image is secure for specific files but may not provide the same level of protection for the entire system.

Can I use both at the same time?

Yes, you can use both. FileVault can encrypt your entire disk, and you can also create encrypting disk images for additional security on specific files.

What happens if I forget my password for FileVault?

If you forget your FileVault password, you can use your recovery key to unlock your disk. If you lose both, you may not be able to access your data.

Is there a performance impact when using FileVault?

There may be a slight performance impact when using FileVault, but modern Macs are optimized for encryption, so the difference is often negligible.
