Macbook Encrypted Dmg Forgot Password

Turn on and set up FileVault

Hi I am trying to recover deleted files from my macbook having Mojave 10.14.4 on it – the drive is APFS encrypted using FileVault but it is unlocked. When I start the software and choose the system drive it asks for the AFPS password. When I type in my login password it says “decrypting Volume” for a few seconds then nothing happens.

How to change an encrypted volume's password in OS X. While encrypting and decrypting a volume can be done on the fly, the option for changing its password is a bit hidden. Dec 09, 2017 I, too, had an encrypted APFS volume that could never be unlocked at the pre-boot Disk Password dialogue. If you wish to regain use of the volume as a startup volume, without restoring from a backup, your best bet may be Recovery OS to decrypt the volume.

FileVault 2 is available in OS X Lion or later. When FileVault is turned on, your Mac always requires that you log in with your account password.

Choose Apple menu () > System Preferences, then click Security & Privacy.
Click the FileVault tab.
Click , then enter an administrator name and password.
Click Turn On FileVault.

If other users have accounts on your Mac, you might see a message that each user must type in their password before they will be able to unlock the disk. For each user, click the Enable User button and enter the user's password. User accounts that you add after turning on FileVault are automatically enabled.

Choose how you want to be able to unlock your disk and reset your password, in case you ever forget your password:

If you're using OS X Yosemite or later, you can choose to use your iCloud account to unlock your disk and reset your password.*
If you're using OS X Mavericks, you can choose to store a FileVault recovery key with Apple by providing the questions and answers to three security questions. Choose answers that you're sure to remember.*
If you don't want to use iCloud FileVault recovery, you can create a local recovery key. Keep the letters and numbers of the key somewhere safe—other than on your encrypted startup disk.

If you lose both your account password and your FileVault recovery key, you won't be able to log in to your Mac or access the data on your startup disk.

Encryption occurs in the background as you use your Mac, and only while your Mac is awake and plugged in to AC power. You can check progress in the FileVault section of Security & Privacy preferences. Any new files that you create are automatically encrypted as they are saved to your startup disk.

When FileVault setup is complete and you restart your Mac, you will use your account password to unlock your disk and allow your Mac to finish starting up. FileVault requires that you log in every time your Mac starts up, and no account is permitted to log in automatically.

Reset your password or change your FileVault recovery key

If you forget your account password or it doesn't work, you might be able to reset your password.

If you want to change the recovery key used to encrypt your startup disk, turn off FileVault in Security & Privacy preferences. You can then turn it on again to generate a new key and disable all older keys.

Turn off FileVault

If you no longer want to encrypt your startup disk, you can turn off FileVault:

Choose Apple menu > System Preferences, then click Security & Privacy.
Click the FileVault tab.
Click , then enter an administrator name and password.
Click Turn Off FileVault.
