  • Your laptop must have a compatible Trusted Platform Module (TPM) chip installed

Apple Mac Laptops can also be encrypted. Apple Mac Laptops are encrypted using Filevault.

  • If you have a new or existing Apple Mac Laptop you will need to arrange with ITD to get it encrypted.
  • Your Apple Mac Laptop will have to be added to the University Active Directory Domain.

3. Next you will be asked to enter a password that will be used to encrypt your portable device.

4. The next step is important in that you will be asked to specify a location for the recovery key for your device. This recovery key will be used in the event you forget your encryption password. You can save it to file or print it but do not save the key to the same removable device.

5. Next you will be asked to select the encryption mode you want to use. The default is compatible mode which will allow the removable device to be used on other computers.
