If the drive was HFS+ (Hierarchical File System) before you chose to encrypt it, it should remain an HFS+ drive afterwards.

MacOS High Sierra continues to support full disk encryption, but Mike Bombich, who created Carbon Copy Cloner, has verified a bug in High Sierra that will cause an external drive to have its format changed from HFS+ to APFS when the drive is encrypted in High Sierra.Д®nabling encryption on a drive should not alter the underlying drive format. This is especially true for portable Mac users, who need to worry about their Macs being lost or stolen.

Full disk encryption has been a boon for Mac users who worry about their personal data being easily accessible on their Macs or external drives.

The tradition lives on with macOS High Sierra, so weвЂ™re gathering a list of what High Sierra broke and how to fix it (when you can).Д®ncrypting an entire drive to add a level of security has been an easy task in the Mac OS ever since FileVault 2 was released as part of OS X Lion. It seems with each new version of the Mac operating system, there are some features that just donвЂ™t seem to work the way they used to. I don't envy sys admins in large academic environments either.ItвЂ™s almost become a tradition one that we wish we didnвЂ™t have to put up with. Seems like there might be some blood on the floor over this one, at least at some organizations. This is probably exercisable remotely if remote logins are enabled (screen sharing, anyway) I don't think anything I did would not be doable through a remote login (but I have not the means to test at the moment). Logs right in, shows the username in the upper left of the screen as 'System Administrator.' The account has root access to the machine. Now when I go to the login screen, I have an 'Other' account showing if I click 'Other' I get a username and password dialog box if I enter 'root' as the username with a blank password Bob's your uncle. Went to the top-level of the file system did a 'Get Info' on a folder I didn't have access to asked it to show me 'Sharing and Permissions' clicked the lock icon to unlock them got a username/password dialog box entered 'root' as the username with a blank password once the dialog box shook and cleared entered 'root' with a blank password again, and the action completed with the lock unlocked. I logged into a non-privileged account that I keep around for testing purposes. My login screen is set to only offer the pre-defined user accounts. I have a MacBook Pro that I upgraded to High Sierra (10.13.1) over Thanksgiving. So, keep the account enabled and set a root password right now.'

The Register notes: 'If you have a root account enabled and a password for it set, the black password trick will not work. Developer Lemi Orhan Ergan was the first to alert the world to the flaw. And while obviously this situation is not the end of the world - it's certainly far from a remote hole or a disk decryption technique - it's just really, really sad to see megabucks Apple drop the ball like this. You should not leave your vulnerable Mac unattended until you can fix the problem.

The vulnerability effectively allows someone with physical access to the machine to log in, cause extra mischief, install malware, and so on. You can do this from the user login screen. If you type in 'root' as the username, leave the password box blank, hit 'enter' and then click on unlock a few times, the prompt disappears and, congrats, you now have admin rights. The security bug is triggered via the authentication dialog box in Apple's operating system, which prompts you for an administrator's username and password when you need to do stuff like configure privacy and network settings. An anonymous reader quotes a report from The Register: A trivial-to-exploit flaw in macOS High Sierra, aka macOS 10.13, allows users to gain admin rights, or log in as root, without a password.
