FileVault is a disk encryption program in macOS that helps protect your data by encrypting the entire hard drive on your Mac. When FileVault is enabled, it encrypts the data on your disk using XTS-AES-128 encryption with a secure key. This means that even if someone gains physical access to your Mac, they won't be able to access your data without the encryption key. FileVault also requires a password or recovery key to unlock the encrypted disk, providing an extra layer of security. **

FileVault can be set to not be turned off by enabling a feature called "FileVault Master Key Redirection." This feature allows the FileVault recovery key to be stored in a secure location, such as a centralized management system, rather than on the local machine. By doing this, even if a user tries to disable FileVault, the recovery key will still be required to decrypt the drive, preventing unauthorized access to the data. This provides an extra layer of security and ensures that FileVault remains active at all times. **

To prevent FileVault from being turned off, you can set a firmware password on your Mac. This will require a password to be entered before any changes can be made to the startup disk, including disabling FileVault. Additionally, you can create a standard user account for everyday use and only use an administrator account when necessary, as FileVault can only be turned off from an administrator account. Regularly updating your Mac's operating system and security settings can also help prevent unauthorized changes to FileVault settings. **

Decrypting macOS FileVault with Windows is not a straightforward process, as Windows does not natively support the FileVault encryption format. However, there are third-party software solutions available that can help decrypt FileVault on a Windows system. One option is to use a tool like Passware Kit Forensic, which is capable of decrypting FileVault volumes on a Windows machine. It's important to note that using third-party software to decrypt FileVault may come with risks, so it's essential to thoroughly research and understand the implications before proceeding. **

To decrypt APFS encrypted FileVault files on different Macs, you will need to have the password or recovery key used to encrypt the files. Once you have this information, you can use the Disk Utility on the new Mac to mount the encrypted drive and enter the password or recovery key to decrypt the files. It is important to note that you will need to have the necessary permissions and access rights to decrypt the files on a different Mac. **

To decrypt FileVault files encrypted with APFS on different Macs, you will need the password or recovery key that was used to encrypt the files originally. Once you have this information, you can use it to unlock the encrypted drive on any Mac by booting into recovery mode and using Disk Utility to unlock and mount the encrypted volume. From there, you can access and decrypt the files as needed. It is important to have the correct password or recovery key to successfully decrypt the files. **
