FileVault is the native data encryption tool for OS X Mavericks (10.9) and later. FileVault uses a whole disk encryption schema similar to BitLocker (the native Windows encryption client). It is the recommended solution for enabling encryption on a Mac computer.
|Before enabling FileVault
Once you are ready to activate FileVault, follow these instructions in The Knowledge Base:
- Recover Key: It depends how your machine was encrypted. If the machine was encrypted manually then IS&T will not be able to recover it for you. It is possible the key is stored in iCloud. If you are unsure how your machine was encrypted it is likely the key is escrowed in Casper. Contact your IT Technician or the Help Desk at 617.253.1101, firstname.lastname@example.org, or by submitting a request online (http://ist.mit.edu/help).
