We entered keepthisSecret as the password and The hint should be shown as the hint.Disk Utility prompted us for a password (twice) and an optional hint.We erased a USB disk and created a new APFS (Encrypted) volume on it.It turns out that the APFS support in the High Sierra version of Disk Utility has feet of clay, as we’ll show here. There are two main disk management tools in macOS – the easy-to-use graphical tool Disk Utility, and the super-powerful but arcane command line program diskutil. This means new drivers inside the operating system to support disks formatted with the new system, and new features in Apple’s disk management utilities to prepare APFS disk volumes for use. New drivers, new utilitiesĪPFS was introduced as Apple’s default and preferred filing system in High Sierra. By some accounts, APFS was long overdue: HFS Plus dated from the early days of Mac OS, and wasn’t really designed for the Unix core that was introduced in OS X (now macOS).įor example, HFS Plus can’t deal with dates after 2040, and doesn’t allow multiple processes to access the filesystem at the same time, making it more sluggish and less future-proof than other widely-used filing systems such as NTFS on Windows and ext4 on Linux.
