Can someone explain the new Mac format ? Mac OS X Journed, Encypyted in Disk Utility? I think this is part of 10.7.3. Having not done this yet, I also see references in articles to FileVault 2. Since FileVault is an encryption by itself, what difference would the new mac OS X format make over FV? Also, how secure is the new bootable format.... e.g. AES and where/how is it stored? Thank for the info.
