![]() Even though you attach the encrypted startup disk to another T2 or Apple silicon Mac, you still won't be able to unlock it because the UID root cryptographic key is device-specific.Computer users keep all kinds of content on the storage media, including crucial work documents, private files, photos, etc., so it is of great necessity to protect this information from unauthorized access. That is the quickest and most secure way to shut everybody out of your Mac.Īs a result, when you use iBoysoft Data Recovery for Mac to scan your startup disk from a T2-secured or Apple silicon-equipped Mac, no password will be accepted to unlock the startup disk. To avoid data leaks after your Mac is stolen or lost or before you sell or give away your device, Apple allows users to remotely erase your Mac by completely wiping the UID root cryptographic key. The most possible reason why you can't unlock the hard drive from a Mac with a T2 security chip or Apple silicon is that the disk is remotely wiped in Find My app on another Apple device. ![]() In addition, the hard disk requires no user password to unlock but the unique ID (UID) root cryptographic key which is randomly generated by the Secure Enclave TRNG (True Random Number Generator) and fused into the SoC at manufacturing along with a GID (Device Group ID) by the Secure Enclave AES Engine. If you do not encrypt your startup disk by FileVault, an encrypted file system, or other encryption methods, your hard disk is still encrypted by the Apple processor. If you turned on FileVault 2, the native full-disk encryption feature in macOS beginning from OS X 10.7, to encrypt Mac's internal startup disk, you will have one of the two or three ways (depending on which version of macOS you are using) to unlock a FileVault-enabled disk.ĭrive is encrypted by Apple's T2 security chip and Apple siliconĪ Mac with a T2 security chip and Apple silicon uses the Secure Enclave subsystem to provide an extra layer of security to your Mac and keep sensitive data secure on Mac's startup disk. The startup disk is encrypted by FileVault 2 Find the correct password and recovery key according to your disk type. The disk is encrypted by FileVault 2Ī FileVault-protected hard disk can be unlocked either by the correct password or recovery key. Then you can use iBoysoft Data Recovery for Mac to scan it for lost data. In this scenario, you need to install the same application that you used to encrypt your drive and unlock it using the app. The same is true for iBoysoft Data Recovery for Mac. However, the drive encrypted by a third-party service probably can't be recognized or unlocked on Mac without according software. ![]() Using third-party software to encrypt and protect data is a common practice. The hard drive or volume is encrypted by a third-party encryption application So, iBoysoft Data Recovery for Mac will report your password is not working. As a result, even with a correct password, you can't unlock your encrypted APFS volumes or hard drives. ![]() Reformatting an encrypted APFS disk will destroy or wipe the intermediary key stored on the disk that is decrypted under the correct password input. If you changed the password, try to recall the new password for it.Īnother cause might be your disk or volume has been reformatted. If you copy the password from a file, make sure you don't copy any unnecessary space. The most likely reason why your disk or volume can't be unlocked successfully is that your password is incorrect. If you choose an encrypted APFS as the file system for your disk or a volume, you will be required to manually set up a password when creating.
