"EEMac has been superseded by McAfee Management of Native Encryption (MNE) 1.0."
Eh, are you actually taking about McAfee Endpoint Encryption, or the more recent McAfee Native Encryption? (MNE) The former is a defunct product now, and quite frankly, one of the more horrible products I've had the displeasure of using. If you actually meant the older product, I doubt its even supported anymore (if you can call McAfee's support "support")
To answer the question. the older product used its own encryption method. The latter newer one uses FV2.
So that said, I would not bother with MNE, and just go with FV2 and Casper escrowing the Recovery Keys.
Must of missed that @RobertHammen
Thanks!
