Apple CoreStorage/FileVault/Fusion Drive Volumes

The macOS operating system has the following disk management systems:

FileVault , is a disk encrypted utility;

Fusion Drive is an Apple's hybrid drive technology;

CoreStorage is a logical volume management system.


R‑Studio for Linux supports all these technologies and can unlock their encrypted volumes (hard drives and images ) using either their passwords or recovery keys.

If the volume is partially encrypted, R‑Studio for Linux can recognize which part is encrypted and which isn't. It will  provide a correct access to the unencrypted and encrypted parts of the volume, provided that the correct password is entered.

The Fusion Drive Components tab also allows you to manually disconnect or connect the components, for example, if they are such damaged that R‑Studio for Linux cannot recognize them as parts of a broken Fusion Drive. Select the object from the drop-down box and click the Connect button. R‑Studio for Linux displays the objects it recognizes as the components of the Fusion Drive in blue.
