Truthfully, since it’s unintended behavior, there aren’t many options to fix it. But if you are, you probably feel kind of stuck. You shouldn’t be able to find yourself in this predicament. Users will be greeted with a message indicating that they cannot log into the FileVault user account because “legacy FileVault is not supported on macOS 10.13 and above.” The ProblemĪs indicated in a recent Macworld article, if macOS 10.13 is installed on a system, any active legacy FileVault drives or user accounts become unusable. If you have High Sierra installed, you won’t see the option to toggle FileVault (see above).īecause of that, users can’t even install macOS 10.13 without first disabling legacy FileVault.
It’s simply not usable with the operating system. MacOS 10.13 officially kills off support for legacy FileVault. Enabling it was as simple as de-checking the Turn Off Legacy FileVault toggle.ĭespite the continued support, Apple was presumably planning to phase out legacy FileVault at one point or another. Users simply had to turn it on by going to System Preferences -> Security & Privacy -> FileVault. Still, Apple continued to offer legacy FileVault in subsequent releases. In other words, it’s full disk encryption and a lot better than legacy FileVault. It then uses a specialized startup procedure to decrypt that volume. Instead of using a sparse disk image, FileVault encrypts a user’s entire startup volume. FileVault 2, which is now just called FileVault, is completely redesigned. For example, it only allowed users to encrypt their home directory.Īpple released a new FileVault in OS X Lion 10.7.4. The original FileVault, now called legacy FileVault, was first released in OS X Panther.īasically, legacy FileVault protected a user’s home directory by way of an encrypted sparse disk image.
