macOS encryption enhances security for sensitive files

Encrypting files on macOS enhances data security against unauthorized access. Users can enable FileVault for full-disk encryption, which protects the entire startup disk. This feature requires a password for access and is automatically enabled on Macs with Apple silicon or T2 Security Chip. To encrypt individual files, users can create an encrypted disk image using Disk Utility. This method allows for password-protected storage of sensitive files. Users can choose between AES-128 and AES-256 encryption, with AES-256 offering stronger security for highly sensitive data. It is important to remember the password for encrypted files, as losing it means losing access to the data. Users should also unmount encrypted disk images when not in use and store backups securely. Sharing encrypted files should be done carefully to maintain security.
